Please keep your posts together in this thread.
Please connect the expansion board and send M122 and M122 B#, where # is the can bus address of the expansion board and copy and paste the resulting report here.
What LEDs are lit on the expansion board?
Can you post a photo of your wiring on the expansion board?
; Custom settings are not defined M997 S1You probably shouldn't have this command in config.g Not sure why you would need or want to flash the wifi firmware at boot up, especially on a board that doesn't have a wifi module.

The connections sound pretty standard. This may be a case of premature component failure.
When and where did you purchase the board? It may be covered by warranty.
