I have purchased an EBB42 in March 25, and started testing if a few days ago. I encountered an TMC2209 - IFCNT error. I initially powered the EBB via usb from my laptop and used a temporary twisted jumper wire to Can HL pin behind the EBB white connector from the U2C Can HL pins.
Using this same wiring setup I have flash the EBB42 firmware successfully. But when I attempt to buzz the motor if will throw the IFCNT error. I then hooked up my thermistor temporarily to see if was the Can wiring but have no problem, Klipper was updating the temperature successfully.
Biqu tech support have suggested to power the EBB via the PSU, stating that there may be insufficient power. I hooked it up to my 24V psu, but am still having the same problem. I now suspect there the board is faulty.
