STM32G474e-EVAL - FDCAN2 is not working properly. FDCAN1 does work

[NStei.2]

Hello all,

i am facing an issue with FDCAN2 on the eval board mentioned above. No data is transmitted before and after the transceiver. So the data is stuck in the Tx buffer and not sent out. With FDCAN1 everything works fine and I created a working sending simulation. Is there an issue in the internal mapping? Pins are PB5 and PB13 for correspondig RX and TX before transceiver. Resistor is applied correctly.

Anyone knows there could be a firmware issue here? I check bus activity low level with Oszi and finished with Vector VN1630. If needed i can share code. But maybe not necessary if its known already.

Thanks!

Nils

I'm seeing the exact same problem with FDCAN2 on the STM32G474e-EVAL board. What turned out to be the problem for you? Thanks.
