Change PHY type in sabresd project

[niklasmolin]

Hi.

I'm upgrading the linux image from branch Daisy to Jethro for our board, using Sabresd machine as reference.

But it seems like it can't find the PHY (Vitesse) on our board, getting message:

fec 2188000.ethernet eth0: no PHY, assuming direct connection to switch

and the PHY mask (when it searches for the PHY, is set to 0xFFFFFFFF (printed in function fec_enet_mii_probe)

In the Daisy branch version, it had no problem to detect the PHY.

Is there some changes I need for this in the device tree file or some other config file?

Thanks,

Niklas

I finally had some time to go back and look at this again.

Find an issue in my device tree file.

Included phy = <&phy0>; when setting up the fec.

When I removed this, it scanned through all PHY's and found the PHY located on ID 0.

Hi Niklas

I believe no need to device tree changes. One can try to debug in linux or uboot,

adding printfs and comparing with working version. Also one can try to use

L3.14.38_6ul_LINUX_DOCS (REV L3.14.38_6ul)

GZ (3.4 MB) L3.14.38_6UL_LINUX_DOCS
