[U-Boot] openrd_ultimate GigEth ports not working

[U-Boot] openrd_ultimate GigEth ports not working

[Alex Zeffertt]

Hi list,

I've just bought an OpenRD Ultimate board and I've managed to get u-boot
running on it.  I am building it like this, using the latest u-boot GIT
repo:

 make mrproper CROSS_COMPILE=arm-none-linux-gnueabi-
 make openrd_ultimate_config CROSS_COMPILE=arm-none-linux-gnueabi-
 make u-boot.kwb CROSS_COMPILE=arm-none-linux-gnueabi-

and then I burn the .kwb file into the flash using openocd.

Unfortunately I cannot get the Gig Eth ports to work in u-boot at the
moment.  When I run the following at the command prompt the console just
hangs and I have to reboot:

Marvell>> setenv ipaddr 192.168.1.1
Marvell>> ping 192.168.1.30
 ... board hangs ...

Has anybody else seen this issue?

Thanks in advance for any help you can give.

Alex

I see something similar with the Seagate Dockstar (also Kirkwood) when
using dhcp. It also hangs. I did not test ping.
The 2011.06 snapshot works fine.

Thanks Ralph,

I can confirm that the issue is the same with OpenRD Ultimate.  I.e.
ethernet is not working in HEAD but it is fine on tag v2011.06.

And what says "git bisect" ?

Hi All,
I contacted the author of that commit and this was his response:

Prafulla, does this make any sense to you?

Yes, it is.
In the mainlined driver, D-cache is considered to be off.
In the subsequent patches is it enabled leading the problem.

We need to address some code to handle this or disable D-cache
