Hi!
I have: Board: Artila M501 board with AT91RM9200 U-Boot: 1.1.2 Kernel: 2.6.14-M5 (I know that U-Boot and Kernel are quite old, but I think for my learning purposes it is OK... Will try to update later.)
My problem: I'm trying to run root-fs over nfs... I know that my nfs-server is OK, because I can mount from another linux-pc. But I'm not able to mount nfs from my target-system. And I can't see any package from my target on wireshark which is running on the nfs-server -> So it seems that my target doesn't send any packet to the server or it get lost on my net....
Can you see any problem with my configuration? See configuration and bootlog below:
