When booting kernel I've got the message

"at91_ether: Your bootloader did not configure a MAC address".

Due to that I can not mount root file system throgh NFS.

On other hand , after downloading uImage by tftp and kommand 'bootm' all working well. MAC address in u-boot is configured and written into flash. U-boot sees it too.(printenv shows it).

On the site
http://www.gelato.unsw.edu.au/lxr/sourc ... 91_ether.c
I read that
" - It must always set the MAC address after reset, even if it doesn't
365 * happen to access the Ethernet while it's booting. Some versions of
366 * U-Boot on the AT91RM9200-DK do not do this."

How to workaround all that? Thank you!
Andrew

in uboot add
setenv ethaddr 04:25:fe:ed:00:18
before booting linux.

don't forget a saveenv

This mac-address above is the sample mac from atmel

Hi,

it's already explained here: http://www.at91.com/phpbb/viewtopic.php?t=2646.

There is also a long discussion about that on the arm-linux mailing list.

So please read the u-boot docs and FAQ.

Thank you all! I have fixed the issue.

I have added --->

in at91rm9200dk.c :

int board_late_init(void)
{
/
/* Fix Ethernet Initialization Bug when starting Linux from U-Boot */
#if (CONFIG_COMMANDS & CFG_CMD_NET)
eth_init(gd->bd);
#endif

return 0;
}

in at91rm9200dk.h :

define CONFIG_COMMANDS \
((CONFIG_CMD_DFL | CFG_CMD_MII | CFG_CMD_NET | \
CFG_CMD_DHCP ) & \
~(CFG_CMD_BDI | \
CFG_CMD_IMI | \
CFG_CMD_AUTOSCRIPT | \
CFG_CMD_FPGA | \
CFG_CMD_MISC | \
CFG_CMD_LOADS ))


#define CONFIG_DRIVER_ETHER 1

#define BOARD_LATE_INIT 1
