Hi guys, I have definitively find the problem but not the solution. Canaan made two types of asics:
- 1246 85th/s for non European market with A3201 chips
- 1246 N 85th/s for European market with A3200 chips

My problems is, I have buy replacement parts for 1246 and not 1246 N parts are the same but not the firmware.

So if anyone had a firmware for an Avalon 1246 with A3200 chips please contact me.
