Hello
Since d7c5f6863550 ("ARM: dts: sun8i: a83t: bananapi-m3: Add AXP813 regulator nodes"), my BPIM3 does not have stable ethernet.
from 50% to 100% packet loss.
According to the logs (below), vcc-ephy is disabled during boot
With the following hack, https://paste.pound-python.org/show/6BlmwcE60z0o4GrbAMUU/ (which is a badly d7c5f6863550 revert)
the situation is better (ping with 0% loss), but the bandwitch is unstable low.
So the problem is clearly that the PHY is badly powered.
Regards
