mmcinit command don't run with uboot 3.4.16

[maisondouf]

As I have initiated to bye Sheeva on Ubuntu Forum, somes members call me for support....
Yesterday evening, one of them, want to boot on a SD card and when he types "mmcinit", his plug (bought last week) says somthing like "command doesn't exists".

After typing "help", effectively this command was not listed.
He have a uboot v3.4.16 but standart, not the sata NewIT uboot v3.4.16 with 07/14/09 date.

So I try to make him change his uboot from an USB key.

The command "usb start" find the key.
The command "fatls usb 0:1" well list the 5 or 6 files in the key.
The command "fatinfo usb 0:1" well says the brand, the size (8Go) and the format (FAT32).

BUT, "fatload usb 0:1 0x00800000 uboot.bin" always says that uboot.bin is an invalid FAT entry with a size of 4096 bytes against 471088 !

Is it due to the size of the key ?

Easiest way to upgrade uboot is with a TFTP server.

Code:

setenv ipaddr 192.168.1.101
setenv serverip 192.168.1.10
bubt uboot-3.4.23.bin
reset

I haven't done much with USB sticks along the lines of what you are trying, so I can't comment or explain your results. Use TFTP; it's simple and it works.
