   6 Hardware
   7 ========

   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
  71 - compile the U-boot sources with:
  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:
