TE 04:45 PM MitySOM-335x (ARM Cortex-A8 Based Products) Software Development: RE: KSZ9031 phy support for the 3.2 kernel

Hi Everyone,
Merging in the changes from the tag (mitysom_AM335XPSP_04.06.00.07) worked for us to limit the ethernet speeds for the phy.
I removed the phy fixup function that was being called.
To reduce the speeds I modified the phy... Timothy Entinger

Looking at my JCI kernel branch it does show that it was before we added the micrel phy support. You mentioned we gave you a more updated version with micrel support?
Do you have the following commits in your kernel tree? If so then ... Jonathan Cormier

I haven't tried you're suggestions yet. I will be able to this afternoon.
The kernel source we're using is much further back on the development tree, here's my dmesg output when I boot.

I recently worked on this a bit.
Here are some u-boot patches to disable gigabit in u-boot. This won't affect linux as you've noticed.

We are using a Critical Link BSP for the MitySOM using the AM335x and a baseboard that has the Micrel KSZ9031 ethernet phy on it. For a distro, we are using TI's old Arago distribution running the 3.2 kernel. Support for the phy was no... Timothy Entinger

Those warnings are caused by the uboot environment trying to read external environment setup scripts from the SD card, these scripts aren't present so you get that warning. This feature really was never used and shouldn't of bee... Daniel Vincelette

Dan,
Thanks for the reply. I am able to better control them using an external weak pull down circuit on power up, which gives a determinate state (Low) during boot.
Thanks again for the great ideas.
