Help with error 22

[Jchau405]

Sega Naomi 2 net dimm cf reader,
Error 22 communication error occurred between main board and option board. Arcade ran great for a few weeks and now this error. I have replaced the usb cable that connects the motherboard board to the upper board. Still the same issue.

And help would be appreciated!

I have seen this with mine before... I take the NetDIMM apart - pull the option board off and essentially just reseat everything. I think oxidation builds up on the pins after a while.

This has fixed it for me in the past.
