Hi,
The command ext2load do not work on the OMAP3 EVM.
The command line is: # ext2load mmc 0:2 0x82000000 /boot/uImage
The error is: ext2fs_devread() read error - block
After reading the u-boot source code, I see that the function mmc_bread() in file drivers/mmc/omap3_mmc.c do not return the good value.
So I apply this small patch to fix the problem
Best regards,
Mickael LANOE

Tested this patch on my OMAP3 beagleboard, and it worked fine. Could you please recreate the patch without line-wraps?
