[U-Boot-Users] TSEC/PHY @ MPC834x stopped working
Ben,
after pulling u-boot today ethernet stopped working on my MPC8343 based board (mvBL-M7). I'm using a Vitesse VSC8601 RGMII phy on TSEC0-1.
I know there's some rewriting/clean-up going on ...
What do I have to do to get it working again ? Any new defines introduced lately ?
Obviously the MII interface stopped working, i.e. all reads give 0xFF. Switching back to older U-boot (3-4 weeks ago) works fine.
Any help is welcome.
regards, Andre

Yeah, but none of that's in the main source tree.

Looking here: http://git.denx.de/?p=u-boot.git;a=history;f=drivers/net/tsec.c;h=6e0f2c6fd0...
nothing new has been added except support for a new PHY, and that was about 5 weeks ago.
Any help is welcome.
Sorry, I don't have access to my MPC8349 board right now or I'd try to help more usefully. Maybe you can post some more information.

Ben,
thanks for your quick reply. Looks like you're right - nothing changed regarding network yet.
Maybe it's a cpu specific problem. Kim ? Can you help here ?
regards, Andre

I know of nothing (barring this being the ETHADDR not specified problem) that could have caused this. Can you try using git-bisect?

Some people were caught by the somewhat recent requirement for an /aliases node and properties pointing to the "real" ethernet node (which is a Good Thing[tm] because it makes the code board agnostic, pushes the board configuration into the .dts where it belongs).
I don't associate Andre's assertion:
Obviously the MII interface stopped working, i.e. all reads give 0xFF.
with the symptoms caused by a missing /aliases node. Maybe, maybe not, could be my lack of experience.
Best regards, gvb
Jerry,
I don't understand this.
The code is far from using the device tree - the dtb is fetched by tftp right after bootp.
It's the initial bootp/dhcp that doesn't work....

Kim,
this is a fully configured board, i.e. serial# and ethaddr/eth1addr set up correctly.
I'll give the bisect a try a soon as there'll be some time.

just to clarify, are you using the mainline u-boot.git tree, or u-boot-mpc83xx.git? you should be using the latter until I ask WD to pull. Actually, if you can confirm it corrects your problem, I have no reason to delay it further (I was waiting for WD to get back from vacation).

Kim,
I'm running from mainline. Do you want me to give u-boot-mpc83xx.git a try ?
After all I think the problem is lurking on my hardware/network somewhere.
I need some more time ...
