Uboot menu concept

U-Boot menu concept for AC100

• Working boot menu example from TI: http://git.denx.de/?p=u-boot.git;a=blob;f=board/ait/cam_enc_4xx/cam_enc_4xx.c;h=644c445693b740936d43e8d1c6e5cfec5451ab03;hb=master
• Uboot menu documentation with example: http://git.denx.de/?p=u-boot.git;a=blob;f=doc/README.menu;h=a8999cab51188c1e12c09e38f2cde8c15d4415e1;hb=master

Our menu

• Uboot start with boot delay say 5, if no key pressed auto start or our defined env

• If key pressed show menu

• Menu contain

• • Boot from MMC's
    • Choose mmc0 (internal flash) or mmc1 (sdcard) default variants which search for /boot and boot.scr
      • Ability to choose recovery or normal boot

• • Boot from USB
    • Same as from MMC's

• • Boot by direct raw reading from MMC0
    • Legacy compatibility
    • First option boot recovery, mmc read recovery kernel and initrd
    • Second option normal boot

Run commands example

mmc dev 0
mmc read 0x1000000 0x3404 0x12ac   
mmc read 0x2200000 0x46b0 0x150
bootz 0x1000000 0x2200000

mmc read syntax: mmc read <addr in memory to which store read data> <sectors to read from start, multiple to 512 bytes>

• • • • For booting boot.img stuff with mmc read kernel must contain working cmdline or find way parse one from emmc

• • Exit to U-Boot console

• • Reset device

Fastboot legacy info

• Android boot.img offsets
  • Похожу эта инфа устарела или я не правильно понимаю, но у boot.img формат по виду другой
