I did connect to serial on V1 and was able to run initramfs from re220-v2. It mostly worked.
In referenced post, I looked at the differences for the re220-v2 and various re200 models. Didn't see much different. I'm just not sure how to take the next step.
Question for devs: Is the .id value in the platform.sh defined solely in OpenWRT code or does it have to match some existing value from the hardware?
For the serial connection, the holes are there. The case is glued shut. Only way I found was to cut it with roto tool cutoff wheel.
Here are some pics:
RE220-v1-serial1
RE2220-v1-serial2
RE220-v3-serial On V3 the holes are a little farther away from the power end.
