[U-Boot] Uboot PING with MII AT91SAM9g20EK

[Abhishek Ashtekar]

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
