It appears, that binary nand uboot provided in the Android4SAM web-site, and also the source code, doesn't support the ethernet option in uboot on SAM9M10EKES.

I installed the uboot from Linux4SAM website, and it works. what's is the issue here ?

I installed the ftp://www.at91.com/pub/uboot/u-boot-1.3 ... dflash.bin binary I took from Android4sam, and the ethernet works with it. but I need to build it now to change few things, and I don't manage to do so.

The Linux4SAM version of the experimental patch is 4, while the android4sam version is 5, what is the difference between the two ?

Can someone please assist with that ?

Hi ramonf,

The ethernet was removed from u-boot for faster boot speed,you can add it if you want.
