Hi All,
I would like to know how to boot linux kernel from USB. I have
ported UBoot
(support serial, USB driver) but didn't support CF card.
Would you please tell me how to boot Linux Kernel from USB Flash memory?
I have
many guide could help hows to boot Linux kernel from CF card or network
but I
didn't see help for USB Flash memory.
Here is step by step I did but didn't work.
- First initialization USB
=> usb start
- List file on USB Flash memory
=> fatls usb 0:1
3876248 vmlinux.srec
1348231 vmlinux
2207942 vmlinux.bin
.
1277956 zimage
- load zImage into SDRAM memory at base address 0x8c000000 + 200000
=> fatload usb 0:1 200000 zimage
reading zimage

Wrong Image Format for bootm command
ERROR: can't get kernel image!
This seems here is wrong command. I should load uImage (not zImage)
into SDRAM
memory. Google booting kernel from USB on the internet but I
didn't see any help. :(
Thank you for answer
