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.
So you still have the issue without trying my suggestion above?
I don't know where you buy the control board but if you want to flash the control board contact the Canaan because their download page does not have firmware you need to contact them before they give you the firmware.
