Note that if the GPIO device uses I2C, then the I2C interface
must also be configured. See I2C Support, below.
+- I/O tracing:
+ When CONFIG_IO_TRACE is selected, U-Boot intercepts all I/O
+ accesses and can checksum them or write a list of them out
+ to memory. See the 'iotrace' command for details. This is
+ useful for testing device drivers since it can confirm that
+ the driver behaves the same way before and after a code
+ change. Currently this is supported on sandbox and arm. To
+ add support for your architecture, add '#include <iotrace.h>'
+ to the bottom of arch/<arch>/include/asm/io.h and test.
+
+ Example output from the 'iotrace stats' command is below.
+ Note that if the trace buffer is exhausted, the checksum will
+ still continue to operate.
+
+ iotrace is enabled
+ Start: 10000000 (buffer start address)
+ Size: 00010000 (buffer size)
+ Offset: 00000120 (current buffer offset)
+ Output: 10000120 (start + offset)
+ Count: 00000018 (number of trace records)
+ CRC32: 9526fb66 (CRC32 of all trace records)
+
- Timestamp Support:
When CONFIG_TIMESTAMP is selected, the timestamp
and make sure that your definition of IMAP_ADDR uses the same value
as your U-Boot configuration in CONFIG_SYS_IMMR.
+Note that U-Boot now has a driver model, a unified model for drivers.
+If you are adding a new driver, plumb it into driver model. If there
+is no uclass available, you are encouraged to create one. See
+doc/driver-model.

You cannot use more than one of these options at the same time.
To use a device tree file that you have compiled yourself, pass
-DEV_TREE_BIN=<filename> to 'make', as in:
+EXT_DTB=<filename> to 'make', as in:
- make DEV_TREE_BIN=boot/am335x-boneblack-pubkey.dtb
+ make EXT_DTB=boot/am335x-boneblack-pubkey.dtb
Then U-Boot will copy that file to u-boot.dtb, put it in the .img file
if used, and u-boot-dtb.bin.
Platform Data
-------------
-Where does the platform data come from? See demo-pdata.c which
+Platform data is like Linux platform data, if you are familiar with that.
+It provides the board-specific information to start up a device.
+
+Why is this information not just stored in the device driver itself? The
+idea is that the device driver is generic, and can in principle operate on
+any board that has that type of device. For example, with modern
+highly-complex SoCs it is common for the IP to come from an IP vendor, and
+therefore (for example) the MMC controller may be the same on chips from
+different vendors. It makes no sense to write independent drivers for the
+MMC controller on each vendor's SoC, when they are all almost the same.
+Similarly, we may have 6 UARTs in an SoC, all of which are mostly the same,
+but lie at different addresses in the address space.
+
+Using the UART example, we have a single driver and it is instantiated 6
+times by supplying 6 lots of platform data. Each lot of platform data
+gives the driver name and a pointer to a structure containing information
+about this instance - e.g. the address of the register space. It may be that
+one of the UARTS supports RS-485 operation - this can be added as a flag in
+the platform data, which is set for this one port and clear for the rest.
+
+Think of your driver as a generic piece of code which knows how to talk to
+a device, but needs to know where it is, any variant/option information and
+so on. Platform data provides this link between the generic piece of code
+and the specific way it is bound on a particular board.
+
+Examples of platform data include:
+
+ - The base address of the IP block's register space
+ - Configuration options, like:
+ - the SPI polarity and maximum speed for a SPI controller
+ - the I2C speed to use for an I2C device
+ - the number of GPIOs available in a GPIO device
+
+Where does the platform data come from? It is either held in a structure
+which is compiled into U-Boot, or it can be parsed from the Device Tree
+(see 'Device Tree' below).
+
+For an example of how it can be compiled in, see demo-pdata.c which
sets up a table of driver names and their associated platform data.
The data can be interpreted by the drivers however they like - it is
basically a communication scheme between the board-specific code and
sides = <4>;
};
+This means that instead of having lots of U_BOOT_DEVICE() declarations in
+the board file, we put these in the device tree. This approach allows a lot
+more generality, since the same board file can support many types of boards
+(e,g. with the same SoC) just by using different device trees. An added
+benefit is that the Linux device tree can be used, thus further simplifying
+the task of board-bring up either for U-Boot or Linux devs (whoever gets to
+the board first!).
The easiest way to make this work it to add a few members to the driver:
.platdata_auto_alloc_size = sizeof(struct dm_test_pdata),
.ofdata_to_platdata = testfdt_ofdata_to_platdata,
- .probe = testfdt_drv_probe,
The 'auto_alloc' feature allowed space for the platdata to be allocated
-and zeroed before the driver's ofdata_to_platdata method is called. This
-method reads the information out of the device tree and puts it in
-dev->platdata. Then the probe method is called to set up the device.
+and zeroed before the driver's ofdata_to_platdata() method is called. The
+ofdata_to_platdata() method, which the driver write supplies, should parse
+the device tree node for this device and place it in dev->platdata. Thus
+when the probe method is called later (to set up the device ready for use)
+the platform data will be present.
Note that both methods are optional. If you provide an ofdata_to_platdata
-method then it will be called first (after bind). If you provide a probe
-method it will be called next.
+method then it will be called first (during activation). If you provide a
+probe method it will be called next. See Driver Lifecycle below for more
+details.
If you don't want to have the platdata automatically allocated then you
can leave out platdata_auto_alloc_size. In this case you can use malloc
end of the enum there, then declare your uclass as above.
+Driver Lifecycle
+----------------
+
+Here are the stages that a device goes through in driver model. Note that all
+methods mentioned here are optional - e.g. if there is no probe() method for
+a device then it will not be called. A simple device may have very few
+methods actually defined.
+
+1. Bind stage
+
+A device and its driver are bound using one of these two methods:
+
+ - Scan the U_BOOT_DEVICE() definitions. U-Boot It looks up the
+name specified by each, to find the appropriate driver. It then calls
+device_bind() to create a new device and bind' it to its driver. This will
+call the device's bind() method.
+
+ - Scan through the device tree definitions. U-Boot looks at top-level
+nodes in the the device tree. It looks at the compatible string in each node
+and uses the of_match part of the U_BOOT_DRIVER() structure to find the
+right driver for each node. It then calls device_bind() to bind the
+newly-created device to its driver (thereby creating a device structure).
+This will also call the device's bind() method.
+
+At this point all the devices are known, and bound to their drivers. There
+is a 'struct udevice' allocated for all devices. However, nothing has been
+activated (except for the root device). Each bound device that was created
+from a U_BOOT_DEVICE() declaration will hold the platdata pointer specified
+in that declaration. For a bound device created from the device tree,
+platdata will be NULL, but of_offset will be the offset of the device tree
+node that caused the device to be created. The uclass is set correctly for
+the device.
+
+The device's bind() method is permitted to perform simple actions, but
+should not scan the device tree node, not initialise hardware, nor set up
+structures or allocate memory. All of these tasks should be left for
+the probe() method.
+
+Note that compared to Linux, U-Boot's driver model has a separate step of
+probe/remove which is independent of bind/unbind. This is partly because in
+U-Boot it may be expensive to probe devices and we don't want to do it until
+they are needed, or perhaps until after relocation.
+
+2. Activation/probe
+
+When a device needs to be used, U-Boot activates it, by following these
+steps (see device_probe()):
+
+ a. If priv_auto_alloc_size is non-zero, then the device-private space
+ is allocated for the device and zeroed. It will be accessible as
+ dev->priv. The driver can put anything it likes in there, but should use
+ it for run-time information, not platform data (which should be static
+ and known before the device is probed).
+
+ b. If platdata_auto_alloc_size is non-zero, then the platform data space
+ is allocated. This is only useful for device tree operation, since
+ otherwise you would have to specific the platform data in the
+ U_BOOT_DEVICE() declaration. The space is allocated for the device and
+ zeroed. It will be accessible as dev->platdata.
+
+ c. If the device's uclass specifies a non-zero per_device_auto_alloc_size,
+ then this space is allocated and zeroed also. It is allocated for and
+ stored in the device, but it is uclass data. owned by the uclass driver.
+ It is possible for the device to access it.
+
+ d. All parent devices are probed. It is not possible to activate a device
+ unless its predecessors (all the way up to the root device) are activated.
+ This means (for example) that an I2C driver will require that its bus
+ be activated.
+
+ e. If the driver provides an ofdata_to_platdata() method, then this is
+ called to convert the device tree data into platform data. This should
+ do various calls like fdtdec_get_int(gd->fdt_blob, dev->of_offset, ...)
+ to access the node and store the resulting information into dev->platdata.
+ After this point, the device works the same way whether it was bound
+ using a device tree node or U_BOOT_DEVICE() structure. In either case,
+ the platform data is now stored in the platdata structure. Typically you
+ will use the platdata_auto_alloc_size feature to specify the size of the
+ platform data structure, and U-Boot will automatically allocate and zero
+ it for you before entry to ofdata_to_platdata(). But if not, you can
+ allocate it yourself in ofdata_to_platdata(). Note that it is preferable
+ to do all the device tree decoding in ofdata_to_platdata() rather than
+ in probe(). (Apart from the ugliness of mixing configuration and run-time
+ data, one day it is possible that U-Boot will cache platformat data for
+ devices which are regularly de/activated).
+
+ f. The device's probe() method is called. This should do anything that
+ is required by the device to get it going. This could include checking
+ that the hardware is actually present, setting up clocks for the
+ hardware and setting up hardware registers to initial values. The code
+ in probe() can access:
+
+ - platform data in dev->platdata (for configuration)
+ - private data in dev->priv (for run-time state)
+ - uclass data in dev->uclass_priv (for things the uclass stores
+ about this device)
+
+ Note: If you don't use priv_auto_alloc_size then you will need to
+ allocate the priv space here yourself. The same applies also to
+ platdata_auto_alloc_size. Remember to free them in the remove() method.
+
+ g. The device is marked 'activated'
+
+ h. The uclass's post_probe() method is called, if one exists. This may
+ cause the uclass to do some housekeeping to record the device as
+ activated and 'known' by the uclass.
+
+3. Running stage
+
+The device is now activated and can be used. From now until it is removed
+all of the above structures are accessible. The device appears in the
+uclass's list of devices (so if the device is in UCLASS_GPIO it will appear
+as a device in the GPIO uclass). This is the 'running' state of the device.
+
+4. Removal stage
+
+When the device is no-longer required, you can call device_remove() to
+remove it. This performs the probe steps in reverse:
+
+ a. The uclass's pre_remove() method is called, if one exists. This may
+ cause the uclass to do some housekeeping to record the device as
+ deactivated and no-longer 'known' by the uclass.
+
+ b. All the device's children are removed. It is not permitted to have
+ an active child device with a non-active parent. This means that
+ device_remove() is called for all the children recursively at this point.
+
+ c. The device's remove() method is called. At this stage nothing has been
+ deallocated so platform data, private data and the uclass data will all
+ still be present. This is where the hardware can be shut down. It is
+ intended that the device be completely inactive at this point, For U-Boot
+ to be sure that no hardware is running, it should be enough to remove
+ all devices.
+
+ d. The device memory is freed (platform data, private data, uclass data).
+
+ Note: Because the platform data for a U_BOOT_DEVICE() is defined with a
+ static pointer, it is not de-allocated during the remove() method. For
+ a device instantiated using the device tree data, the platform data will
+ be dynamically allocated, and thus needs to be deallocated during the
+ remove() method, either:
+
+ 1. if the platdata_auto_alloc_size is non-zero, the deallocation
+ happens automatically within the driver model core; or
+
+ 2. when platdata_auto_alloc_size is 0, both the allocation (in probe()
+ or preferably ofdata_to_platdata()) and the deallocation in remove()
+ are the responsibility of the driver author.
+
+ e. The device is marked inactive. Note that it is still bound, so the
+ device structure itself is not freed at this point. Should the device be
+ activated again, then the cycle starts again at step 2 above.
+
+5. Unbind stage
+
+The device is unbound. This is the step that actually destroys the device.
+If a parent has children these will be destroyed first. After this point
+the device does not exist and its memory has be deallocated.
+

+Verified Boot on the Beaglebone Black
+=====================================
+
+Introduction
+------------
+
+Before reading this, please read verified-boot.txt and signature.txt. These
+instructions are for mainline U-Boot from v2014.07 onwards.
+
+There is quite a bit of documentation in this directory describing how
+verified boot works in U-Boot. There is also a test which runs through the
+entire process of signing an image and running U-Boot (sandbox) to check it.
+However, it might be useful to also have an example on a real board.
+
+Beaglebone Black is a fairly common board so seems to be a reasonable choice
+for an example of how to enable verified boot using U-Boot.
+
+First a note that may to help avoid confusion. U-Boot and Linux both use
+device tree. They may use the same device tree source, but it is seldom useful
+for them to use the exact same binary from the same place. More typically,
+U-Boot has its device tree packaged wtih it, and the kernel's device tree is
+packaged with the kernel. In particular this is important with verified boot,
+since U-Boot's device tree must be immutable. If it can be changed then the
+public keys can be changed and verified boot is useless. An attacker can
+simply generate a new key and put his public key into U-Boot so that
+everything verifies. On the other hand the kernel's device tree typically
+changes when the kernel changes, so it is useful to package an updated device
+tree with the kernel binary. U-Boot supports the latter with its flexible FIT
+format (Flat Image Tree).
+
+
+Overview
+--------
+
+The steps are roughly as follows:
+
+1. Build U-Boot for the board, with the verified boot options enabled.
+
+2. Obtain a suitable Linux kernel
+
+3. Create a Image Tree Source file (ITS) file describing how you want the
+kernel to be packaged, compressed and signed.
+
+4. Create a key pair
+
+5. Sign the kernel
+
+6. Put the public key into U-Boot's image
+
+7. Put U-Boot and the kernel onto the board
+
+8. Try it
+
+
+Step 1: Build U-Boot
+--------------------
+
+a. Set up the environment variable to point to your toolchain. You will need
+this for U-Boot and also for the kernel if you build it. For example if you
+installed a Linaro version manually it might be something like:
+
+ export CROSS_COMPILE=/opt/linaro/gcc-linaro-arm-linux-gnueabihf-4.8-2013.08_linux/bin/arm-linux-gnueabihf-
+
+or if you just installed gcc-arm-linux-gnueabi then it might be
+
+ export CROSS_COMPILE=arm-linux-gnueabi-
+
+b. Configure and build U-Boot with verified boot enabled:
+
+ export ARCH=arm
+ export UBOOT=/path/to/u-boot
+ cd $UBOOT
+ # You can add -j10 if you have 10 CPUs to make it faster
+ make O=b/am335x_boneblack_vboot am335x_boneblack_vboot_config all
+ export UOUT=$UBOOT/b/am335x_boneblack_vboot
+
+c. You will now have a U-Boot image:
+
+ file b/am335x_boneblack_vboot/u-boot-dtb.img
+b/am335x_boneblack_vboot/u-boot-dtb.img: u-boot legacy uImage, U-Boot 2014.07-rc2-00065-g2f69f8, Firmware/ARM, Firmware Image (Not compressed), 395375 bytes, Sat May 31 16:19:04 2014, Load Address: 0x80800000, Entry Point: 0x00000000, Header CRC: 0x0ABD6ACA, Data CRC: 0x36DEF7E4
+
+
+Step 2: Build Linux
+--------------------
+
+a. Find the kernel image ('Image') and device tree (.dtb) file you plan to
+use. In our case it is am335x-boneblack.dtb and it is built with the kernel.
+At the time of writing an SD Boot image can be obtained from here:
+
+ http://www.elinux.org/Beagleboard:Updating_The_Software#Image_For_Booting_From_microSD
+
+You can write this to an SD card and then mount it to extract the kernel and
+device tree files.
+
+You can also build a kernel. Instructions for this are are here:
+
+ http://elinux.org/Building_BBB_Kernel
+
+or you can use your favourite search engine. Following these instructions
+produces a kernel Image and device tree files. For the record the steps were:
+
+ export KERNEL=/path/to/kernel
+ cd $KERNEL
+ git clone git://github.com/beagleboard/kernel.git .
+ git checkout v3.14
+ ./patch.sh
+ cp configs/beaglebone kernel/arch/arm/configs/beaglebone_defconfig
+ cd kernel
+ make beaglebone_defconfig
+ make uImage dtbs # -j10 if you have 10 CPUs
+ export OKERNEL=$KERNEL/kernel/arch/arm/boot
+
+c. You now have the 'Image' and 'am335x-boneblack.dtb' files needed to boot.
+
+
+Step 3: Create the ITS
+----------------------
+
+Set up a directory for your work.
+
+ export WORK=/path/to/dir
+ cd $WORK
+
+Put this into a file in that directory called sign.its:
+
+/dts-v1/;
+
+/ {
+ description = "Beaglebone black";
+ #address-cells = <1>;
+
+ images {
+ kernel@1 {
+ data = /incbin/("Image.lzo");
+ type = "kernel";
+ arch = "arm";
+ os = "linux";
+ compression = "lzo";
+ load = <0x80008000>;
+ entry = <0x80008000>;
+ hash@1 {
+ algo = "sha1";
+ };
+ };
+ fdt@1 {
+ description = "beaglebone-black";
+ data = /incbin/("am335x-boneblack.dtb");
+ type = "flat_dt";
+ arch = "arm";
+ compression = "none";
+ hash@1 {
+ algo = "sha1";
+ };
+ };
+ };
+ configurations {
+ default = "conf@1";
+ conf@1 {
+ kernel = "kernel@1";
+ fdt = "fdt@1";
+ signature@1 {
+ algo = "sha1,rsa2048";
+ key-name-hint = "dev";
+ sign-images = "fdt", "kernel";
+ };
+ };
+ };
+};
+
+
+The explanation for this is all in the documentation you have already read.
+But briefly it packages a kernel and device tree, and provides a single
+configuration to be signed with a key named 'dev'. The kernel is compressed
+with LZO to make it smaller.
+
+
+Step 4: Create a key pair
+-------------------------
+
+See signature.txt for details on this step.
+
+ cd $WORK
+ mkdir keys
+ openssl genrsa -F4 -out keys/dev.key 2048
+ openssl req -batch -new -x509 -key keys/dev.key -out keys/dev.crt
+
+Note: keys/dev.key contains your private key and is very secret. If anyone
+gets access to that file they can sign kernels with it. Keep it secure.
+
+
+Step 5: Sign the kernel
+-----------------------
+
+We need to use mkimage (which was built when you built U-Boot) to package the
+Linux kernel into a FIT (Flat Image Tree, a flexible file format that U-Boot
+can load) using the ITS file you just created.
+
+At the same time we must put the public key into U-Boot device tree, with the
+'required' property, which tells U-Boot that this key must be verified for the
+image to be valid. You will make this key available to U-Boot for booting in
+step 6.
+
+ ln -s $OKERNEL/dts/am335x-boneblack.dtb
+ ln -s $OKERNEL/Image
+ ln -s $UOUT/u-boot-dtb.img
+ cp $UOUT/arch/arm/dts/am335x-boneblack.dtb am335x-boneblack-pubkey.dtb
+ lzop Image
+ $UOUT/tools/mkimage -f sign.its -K am335x-boneblack-pubkey.dtb -k keys -r image.fit
+
+You should see something like this:

+

+
+Signature check OK
+
+
+At the top, you see "sha1,rsa2048:dev+". This means that it checked an RSA key
+of size 2048 bits using SHA1 as the hash algorithm. The key name checked was
+'dev' and the '+' means that it verified. If it showed '-' that would be bad.
+
+Once the configuration is verified it is then possible to rely on the hashes
+in each image referenced by that configuration. So fit_check_sign goes on to
+load each of the images. We have a kernel and an FDT but no ramkdisk. In each
+case fit_check_sign checks the hash and prints sha1+ meaning that the SHA1
+hash verified. This means that none of the images has been tampered with.
+
+There is a test in test/vboot which uses U-Boot's sandbox build to verify that
+the above flow works.
+
+But it is fun to do this by hand, so you can load image.fit into a hex editor
+like ghex, and change a byte in the kernel:
+
+ $UOUT/tools/fit_info -f image.fit -n /images/kernel@1 -p data
+NAME: kernel@1
+LEN: 7790938
+OFF: 168
+
+This tells us that the kernel starts at byte offset 168 (decimal) in image.fit
+and extends for about 7MB. Try changing a byte at 0x2000 (say) and run
+fit_check_sign again. You should see something like:

+
+It has detected the change in the kernel.
+
+You can also be sneaky and try to switch images, using the libfdt utilities
+that come with dtc (package name is device-tree-compiler but you will need a
+recent version like 1.4:
+
+ dtc -v
+Version: DTC 1.4.0
+
+First we can check which nodes are actually hashed by the configuration:
+
+ fdtget -l image.fit /
+images
+configurations
+
+ fdtget -l image.fit /configurations
+conf@1
+fdtget -l image.fit /configurations/conf@1
+signature@1
+
+ fdtget -p image.fit /configurations/conf@1/signature@1
+hashed-strings
+hashed-nodes
+timestamp
+signer-version

+algo

+ fdtget image.fit /configurations/conf@1/signature@1 hashed-nodes
+/ /configurations/conf@1 /images/fdt@1 /images/fdt@1/hash@1 /images/kernel@1 /images/kernel@1/hash@1
+
+This gives us a bit of a look into the signature that mkimage added. Note you
+can also use fdtdump to list the entire device tree.
+
+Say we want to change the kernel that this configuration uses
+(/images/kernel@1). We could just put a new kernel in the image, but we will
+need to change the hash to match. Let's simulate that by changing a byte of
+the hash:
+
+ fdtget -tx image.fit /images/kernel@1/hash@1 value
+c9436464 6427e10f 423837e5 59898ef0 2c97b988
+ fdtput -tx image.fit /images/kernel@1/hash@1 value c9436464 6427e10f 423837e5 59898ef0 2c97b981
+
+Now check it again:
+
+ $UOUT/tools/fit_check_sign -f image.fit -k am335x-boneblack-pubkey.dtb
+Verifying Hash Integrity ... sha1,rsa2048:devrsa_verify_with_keynode: RSA failed to verify: -13
+rsa_verify_with_keynode: RSA failed to verify: -13
+-
+Failed to verify required signature 'key-dev'
+Signature check Bad (error 1)
+
+This time we don't even get as far as checking the images, since the
+configuration signature doesn't match. We can't change any hashes without the
+signature check noticing. The configuration is essentially locked. U-Boot has
+a public key for which it requires a match, and will not permit the use of any
+configuration that does not match that public key. The only way the
+configuration will match is if it was signed by the matching private key.
+
+It would also be possible to add a new signature node that does match your new
+configuration. But that won't work since you are not allowed to change the
+configuration in any way. Try it with a fresh (valid) image if you like by
+running the mkimage link again. Then:
+
+ fdtput -p image.fit /configurations/conf@1/signature@2 value fred
+ $UOUT/tools/fit_check_sign -f image.fit -k am335x-boneblack-pubkey.dtb
+Verifying Hash Integrity ... -

+rsa_verify_with_keynode: RSA failed to verify: -13
+-
+Failed to verify required signature 'key-dev'
+Signature check Bad (error 1)
+
+
+Of course it would be possible to add an entirely new configuration and boot
+with that, but it still needs to be signed, so it won't help.
+
+
+6. Put the public key into U-Boot's image
+-----------------------------------------
+
+Having confirmed that the signature is doing its job, let's try it out in
+U-Boot on the board. U-Boot needs access to the public key corresponding to
+the private key that you signed with so that it can verify any kernels that
+you sign.
+
+ cd $UBOOT
+ make O=b/am335x_boneblack_vboot EXT_DTB=${WORK}/am335x-boneblack-pubkey.dtb
+
+Here we are overrriding the normal device tree file with our one, which
+contains the public key.
+
+Now you have a special U-Boot image with the public key. It can verify can
+kernel that you sign with the private key as in step 5.
+
+If you like you can take a look at the public key information that mkimage
+added to U-Boot's device tree:
+
+ fdtget -p am335x-boneblack-pubkey.dtb /signature/key-dev
+required
+algo
+rsa,r-squared
+rsa,modulus
+rsa,n0-inverse
+rsa,num-bits
+key-name-hint
+
+This has information about the key and some pre-processed values which U-Boot
+can use to verify against it. These values are obtained from the public key
+certificate by mkimage, but require quite a bit of code to generate. To save
+code space in U-Boot, the information is extracted and written in raw form for
+U-Boot to easily use. The same mechanism is used in Google's Chrome OS.
+
+Notice the 'required' property. This marks the key as required - U-Boot will
+not boot any image that does not verify against this key.
+
+
+7. Put U-Boot and the kernel onto the board
+-------------------------------------------
+
+The method here varies depending on how you are booting. For this example we
+are booting from an micro-SD card with two partitions, one for U-Boot and one
+for Linux. Put it into your machine and write U-Boot and the kernel to it.
+Here the card is /dev/sde:
+
+ cd $WORK
+ export UDEV=/dev/sde1 # Change thes two lines to the correct device
+ export KDEV=/dev/sde2
+ sudo mount $UDEV /mnt/tmp && sudo cp $UOUT/u-boot-dtb.img /mnt/tmp/u-boot.img && sleep 1 && sudo umount $UDEV
+ sudo mount $KDEV /mnt/tmp && sudo cp $WORK/image.fit /mnt/tmp/boot/image.fit && sleep 1 && sudo umount $KDEV
+
+
+8. Try it
+---------
+
+Boot the board using the commands below:
+
+ setenv bootargs console=ttyO0,115200n8 quiet root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
+ ext2load mmc 0:2 82000000 /boot/image.fit
+ bootm 82000000
+
+You should then see something like this:
+
+U-Boot# setenv bootargs console=ttyO0,115200n8 quiet root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait
+U-Boot# ext2load mmc 0:2 82000000 /boot/image.fit
+7824930 bytes read in 589 ms (12.7 MiB/s)
+U-Boot# bootm 82000000

+Angstrom v2012.12 - Kernel 3.14.1+
+
+beaglebone login:
+
+At this point your kernel has been verified and you can be sure that it is one
+that you signed. As an exercise, try changing image.fit as in step 5 and see
+what happens.
+
+
+Further Improvements
+--------------------
+
+Several of the steps here can be easily automated. In particular it would be
+capital if signing and packaging a kernel were easy, perhaps a simple make
+target in the kernel.
+
+Some mention of how to use multiple .dtb files in a FIT might be useful.
+
+U-Boot's verified boot mechanism has not had a robust and independent security
+review. Such a review should look at the implementation and its resistance to
+attacks.
+
+Perhaps the verified boot feature could could be integrated into the Amstrom
+distribution.
