NIC not properly initialized in uboot code

[Oliver Grawert]

with the recent uboot 2009.08 with freescale patches applied the FEC NIC doesnt get properly initialized under the running system this results in:

SIOCSIFFLAGS Cannot assign requested address

when running ifconfig eth0 up.

the NIC reportse a hardware address of 00:00:00:00:00:00
trying to initialize the NIC manually at the uboot prompt with setenv ethaddr (using the address printed on the label on the board) does not change the situation.
the file mxc_fec.c in the uboot code also seems to have many inconsistencies and some errors that show up during build.

using:

setenv ethaddr <some random MAC address>
setenv ipaddr <a valid IP of the net the NIC is connected to>

seems to help. but indeed thats not usable in the automated SD card boot we are using since it would enforce to type in the IP each time you boot through serial console ... automated setting of the MAC and initializing of the NIC needs to work as it does under redboot.

Hi All,

  Pls try the patch attached.

  u-boot will not initilized network unless the user has use it to fetch data. If you need to set fec mac addr to fec register, pls apply this patch and set the "fec_addr" environment variable.

  This patch will check if fec_addr exists and set its value to fec register in booting.

  Thanks~~

Yours
Terry

hmm, i dont see any code providing the mxc_fec_set_mac_from_env() function in either the 2009.01 nor the 2009.08 trees, but i'm doing a testbuild nontheless now ... will report back soon ...

[Oliver Grawert (ogra)]

as i expected:

cpu/arm_cortexa8/mx51/libmx51.a(generic.o): In function `cpu_eth_init':
cpu/arm_cortexa8/mx51/generic.c:261: undefined reference to `mxc_fec_set_mac_from_env'

is there another patch i'm missing that is not in the BSP ?

[Oliver Grawert (ogra)]

note btw that we are currently having to use the latest 2009.01 uboot with the patches from the RC BSP (from dec. 9) due to bug #506761
(the error above shows up in a 2009.08 testbuild from the latest BSP as well though)

terry, the patch seem to be incomplete; please check comments #3, #4 and #5

we are going for redboot for imx lucid ... until all bugs are fixed for uboot.

Is this still an issue with using u-boot-linaro?

uboot-imx was removed from the archive, invalidating the task.
