I'm having problems getting my software to work with FDCAN2 on the STM32G474e-EVAL board. It works with FDCAN1, but w/ FDCAN2, messages accumulate in the Tx buffer until I get buffer fill errors.I built the FDCAN_Com_IT example from the latest STM32G...

Ok, finally tracked this problem down. It would appear that some revisions of the STM32G474E-EVAL board default to having the FDCAN2 TX pin disconnected. If you solder the SB5 location on the board closed, the pin will be connected and FDCAN2 will wo...

I'm still experiencing this problem and have reproduced it on multiple boards. JP1, JP2, and JP4 are definitely set correctly and the CN12 and CN10 are correctly wired together. Is there anything else that could be causing this behavior? (Other jumpe...

Ok, that looks like what I'm using as well. I've double checked the jumpers and tested the conductivity of the wires connecting FDCAN1 to FDCAN2 and they're good. Any idea what could be going wrong here to leave FDCAN1 working but FDCAN2 failing? -es

Hi Kaouthar,Thank you for checking on this. I've definitely fitted jumpers JP1, JP2, and JP4 and correctly bridged FDCAN1 and FDCAN2, but I'm still seeing the same failure. What hash did you build the FDCAN_Com_IT example from? -es
