Hello,
Am a new member and this is my first post.
With Version: Uboot -2010.09
I am currently using the AT91SAM9G20EK board and want to use networking interface for tftp, tftpboot etc with the MII Interface.
As the first test, I tried 'ping' command to connected PC and also to the board itself.
PING fails. So I put some extra printf's, to check the behaviour
Also read the EMAC registers ..... seem to be OK.
I have enabled in /include/configs/at91sam9260ek.h
#define CONFIG_MII 1
#define CONFIG_CMD_MII
and also #undef CONFIG_RMII
Is there some patch that needs to be applied or more modifications / additions ?
Thanks a lot.
Regards,
Abhi
PS: Pasted the Output Log
