I've started PR here:
mvebu: Add support for WD Cloud Mirror Gen2
It's somewhat based on old PR/2040 for WD Cloud EX2 Ultra and my digging through forum.doozan.com and most recent mvebu ports.
I'm looking for testers and WD Cloud EX2 Ultra owners for possible future port . One and only difference afaik is 1GB RAM
Also looking for help to implement fixed mac address for eth0 and PWM Fan control / script.
code that got me valid mac:
ubiattach -p /dev/mtd7 -d7
addr=$(grep -o -E '([[:xdigit:]]{1,2}:){5}[[:xdigit:]]{1,2}' /dev/ubi7_0)
or
ubiattach -p /dev/mtd5 -d5
mkdir /tmp/wd-config
mount -o ro -r -t ubifs /dev/ubi5_0 /tmp/wd-config/
cat /tmp/wd-config/mac_addr
or
ubiattach -p /dev/mtd7 -d7
mkdir /tmp/wd-config
mount -o ro -r -t ubifs /dev/ubi7_0 /tmp/wd-config/
cat /tmp/wd-config/mac_addr
