| 3 | ||
| 4 | This document covers various features of the 'am335x_shc' build. | |
| 5 | ||
| 6 | Hardware | |
| 7 | ======== | |
| 8 | ||
| 9 | AM335X based board: | |
| 10 | ||
| 11 | I2C: ready | |
| 12 | DRAM: 512 MiB | |
| 13 | Enabling the D-Cache | |
| 14 | MMC: OMAP SD/MMC: 0 @ 26 MHz, OMAP SD/MMC: 1 @ 26 MHz | |
| 15 | Net: cpsw | |
| 16 | ||
| 17 | Following boot options are possible: | |
| 18 | ||
| 19 | 2 Jumpers: | |
| 20 | ||
| 21 | Jumper 1 Jumper 2 Bootmode | |
| 22 | off off eMMC boot | |
| 23 | on off SD boot | |
| 24 | off on Net boot | |
| 25 | ||
| 26 | Compiling | |
| 27 | ========= | |
| 28 | ||
| 29 | $ make am335x_shc_defconfig | |
| 30 | HOSTCC scripts/basic/fixdep | |
| 31 | HOSTCC scripts/kconfig/conf.o | |
| 32 | SHIPPED scripts/kconfig/zconf.tab.c | |
| 33 | SHIPPED scripts/kconfig/zconf.lex.c | |
| 34 | SHIPPED scripts/kconfig/zconf.hash.c | |
| 35 | HOSTCC scripts/kconfig/zconf.tab.o | |
| 36 | HOSTLD scripts/kconfig/conf | |
| 37 | # | |
| 38 | # configuration written to .config | |
| 39 | # | |
| 40 | $ make -s all | |
| 41 | ||
| 42 | -> now you have the MLO and the u-boot.img file, you can put | |
| 43 | on your SD card or eMMC. | |
| 44 | ||
| 45 | Configuring | |
| 46 | =========== | |
| 47 | ||
| 48 | There are a lot of board versions and boot configurations, which | |
| 49 | can be selected through "make menuconfig" | |
| 50 | ||
| 51 | ARM architecture ---> | |
| 52 | enable different boot versions for the shc board (enable eMMC) ---> | |
| 53 | (X) enable eMMC | |
| 54 | ( ) enable ICT | |
| 55 | ( ) enable NETBOOT | |
| 56 | ( ) enable SDBOOT | |
| 57 | ||
| 58 | enable different board versions for the shc board (C3 Sample board version) ---> | |
| 59 | ( ) B Sample board version | |
| 60 | ( ) B2 Sample board version | |
| 61 | ( ) C Sample board version | |
| 62 | ( ) C2 Sample board version | |
| 63 | (X) C3 Sample board version | |
| 64 | ( ) Series board version | |
| 65 | ||
| 66 | Netboot | |
| 67 | ======= | |
| 68 | - see also doc/SPL/README.am335x-network | |
| 69 | ||
| 70 | - set the jumper into netboot mode | |
| 1be82afa | 71 | - compile the U-Boot sources with: |
| d8ccbe93 HS |
72 | make am335x_shc_netboot_defconfig |
| 73 | make all | |
| 74 | - copy the images into your tftp boot directory | |
| 75 | cp spl/u-boot-spl.bin /tftpboot/.../u-boot-spl-restore.bin | |
| 76 | cp u-boot.img /tftpboot/.../u-boot-restore.img | |
| 77 | - power on the board, and you should get something like this: | |
