I got a new board revision of the Olimex A20-OLInuXino-MICRO Board (Rev. J).

It works with the by Olimex provided Jessie image but not with Armbian_5.25_Micro_Debian_jessie_next_4.9.7.

I get no IP address by DHCP because the ethernet is not working.

 

The reason could be an new ethernet chipset they introduced with this revision.

New: Microchip's LAN8710AI-EZK(QFN-32).

Before: Realtek RTL8201CP(LQFP-48)

 

They publish a patch on:

https://github.com/OLIMEX/OLINUXINO/blob/master/SOFTWARE/A20/A20-build-3.4.103-release-5/a20-phy_1000_100-dram.patch
 

That patch can't directly be used on mainline kernel, while it can most likely be applied on our old 3.4.113 kernel ... Unfortunately we don't have this hardware to test but luckily I am meeting Olimex people this weekend and will brought up this issue.
