Dear all, In the previous patch i removed the code from the section below.

The u-boot works but when I try to use nfs as root filesystem i encounter the following issue: ............. MACB_mii_bus: probed eth0: Atmel MACB at 0xfffc4000 irq 21 (00:00:00:00:00:00) eth0: attached PHY driver [KS8721BL] (mii_bus:phy_addr=ffffffff:01, irq=-1) ............. From previous messages i understand that the MAC is set to 00:00:00:00:00:00 which is bad. IP-Config: Failed to open eth0 I used again setenv ethaddr 00:04:25:12:34:56 in u-boot. After saveenv and reboot i used md command to display the EMAC 0xFFFC4000 (named MACB in the driver ) registers U-Boot> md 0xfff4c000 fff4c000: 00000000 00000000 00000000 00000000 ................ fff4c010: 00000000 00000000 00000000 00000000 ................ fff4c020: 00000000 00000000 00000000 00000000 ................ fff4c030: 00000000 00000000 00000000 00000000 ................ fff4c040: 00000000 00000000 00000000 00000000 ................ fff4c050: 00000000 00000000 00000000 00000000 ................ fff4c060: 00000000 00000000 00000000 00000000 ................ fff4c070: 00000000 00000000 00000000 00000000 ................ fff4c080: 00000000 00000000 00000000 00000000 ................ fff4c090: 00000000 00000000 00000000 00000000 ................ fff4c0a0: 00000000 00000000 00000000 00000000 ................ fff4c0b0: 00000000 00000000 00000000 00000000 ................ fff4c0c0: 00000000 00000000 00000000 00000000 ................ fff4c0d0: 00000000 00000000 00000000 00000000 ................ fff4c0e0: 00000000 00000000 00000000 00004000 [EMAIL PROTECTED] fff4c0f0: 53504932 20202020 00010154 00000190 2IPS T....... Offset 0x98 Specific Address 1 Bottom Register EMAC_SA1B Read-write Offset 0x9C Specific Address 1 Top Register EMAC_SA1T Read-write The register EMAC_SA1T and EMAC_SA1B coresponding to top and bottom of the MAC address are 0 Nfs works only with the ugly code that was removed. I'm spinning in a circle :( Please send me any suggestion.
