Hi,

i have 2 devices here i currently try this series.

1x Bananapi R64 v0.1 (mt7622 SOC) with rtl8367s (sgmii+rgmii) - configured to use extport 2 in rgmii mode
1x Bananapi R2 Pro v0 (rk3568 SOC) with rtl8367RB (rgmii+rgmii) - configured to use extport 1 in rgmii mode

on both devices i get mdio running after additional reset in probe and ports are
recognizing link up (got the real port-reg-mapping)

on r64 i get pings working but tcp (ssh, http) seems not working.
on r2pro i cannot get even ping working (but rk3568 gmac seems to come
up).

Luiz, any comments regarding this? I suppose if the chip ID/revision is
the same for both 67S and 67RB, they should work pretty much the same,
right?

but i'm not deep enough in driver coding to find out whats wrong not having technical documents for checking registers to values needed.

Ping working but TCP not working is a bit strange. You could check the
output of ethtool -S and see if that meets your expectations. If you
have a relatively modern ethtool you can also append --all-groups to the
comment to get a more standard output.

You can also try adjusting the RGMII TX/RX delay and pause settings -
that might help for the R2 where you aren't getting any packets
through.
