U-Boot MultiBoot
this setup will allow you to boot off usb/esata/external-sd/internal-sd.
It will auto test all 3 in order of sdb >> sdb >> sda
Enter the following lines to enable multiboot:
external usb-hd:
setenv bootcmd_sdb 'setenv bootargs console=ttyS0,115200 root=/dev/da2s2 panic=10 rootwait; usb start; run boot_sdc;'
setenv boot_sdb 'fatload usb 2:1 0x00900000 kernel-head; go 0x00900000;'
external-sd:
setenv bootcmd_sdb 'setenv bootargs console=ttyS0,115200 root=/dev/da2s2 panic=10 rootwait; usb start; run boot_sdb;'
setenv boot_sdb 'fatload usb 1:1 0x00900000 kernel-head; go 0x00900000;'
internal-sd:
setenv bootcmd_sda '${bootcmd_eth}; ${x_bootcmd_usb}; ${x_bootcmd_kernel}; setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm 0x6400000;'
setenv bootcmd_eth 'setenv ethact egiga0; ${x_bootcmd_ethernet}'
setenv clear_kernel_in_mem 'echo Purging kernel in memory; mw 0x6400000 0x0 0x300000'
setenv bootcmd 'run clear_kernel_in_mem; run bootcmd_sdc; run bootcmd_sdb; run bootcmd_sda'
finally save the changes:
saveenv
