[U-Boot] Olimex-A20-EVB ethernet stops working with latest U-boot, works with tag v2016.01
Good morning all
I updated to latest u-boot yesterday (git pull) and ethernet was not working
reverted to tag v2016.01 with the command
$ git checkout tags/v2016.01
rebuilt, uploaded and ethernet works
As far as I can tell the only difference on the two tests (just a simple ping 192.168.1.1) is the u-boot version Ethernet cable was not moved and I manage to load u-boot using FEL
I can do further tests is any of you is interested.
Thanks, Damiano
Hi Damiano,
Can you try revert the following patch and retest on your board? " commit a058052c358c3ecf5f394ff37def6a45eb26768c Author: Stefan Agner stefan@agner.ch Date: Wed Dec 9 11:21:25 2015 -0800
net: phy: do not read configuration register on reset
When doing a software reset, the reset flag should be written without other bits set. Writing the current state will lead to restoring the state of the PHY (e.g. Powerdown), which is not what is expected from a software reset. Signed-off-by: Stefan Agner stefan@agner.ch "
This patch breaks ethernet function of i.MX6 Quad Sabresd/Quad Sabreauto. Not sure whether reverting this patch can help in your case or not. Please try.
Thanks, Peng.

Thanks & Regards,
