[U-Boot] [UBoot] Hows to boot Linux Kernel from USB

[thaoth <thaoth@cybersoft-vn.com>]

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
.
.
.
.
................................................................................

1277956 bytes read

=> bootm
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
Best regards,
