hello!
I would like to ask someone who owns an old Rock Pi 4C v1.2 board to check the Ethernet chip model on the board.
Is it RTL8211E or RTL8211C?
The chip package format is QFN-48 I suppose.. but Im not sure because as far I know - 48 pin RTL8211C seems exist only in LQFP48 format.
so there is also a question - how to check - which is format RTL chip on the board?
thank you!
found this
looks like it should be 8211E QNF-48..
You can also check phy_id in sysfs, and compare its value with r8169 driver to find the matching chip model.
EDIT: looks like this is related to Rock Pi 4c - no ethernet - #17 by RadxaYuntian
thank you but unfortunately on my board this chip is broken so I cannot check it:
