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,
