Hello,
I'm trying to build a U-Boot from your git tree with the AT91 patches.
My board is a custom board with a KS8721 instead of the DM9161 network
PHY chip. This is the same chip as Olimex used on their development board.
Olimex build a U-Boot for their board, they did some code hacking on
u-boot. As far as I know they did the following to get the ethernet up
and running. [1] This is in the board/at91sam9260ek/dm9161a.c file
On the latest git version with the AT91 patches the ethernet driver is
called macb??!!
Do you know how I can get this working? (as hack and in the future more
clean)
Kind regards,
Sander Vermin
