Hello William I have the same problem as Markus has. I've done the same as Markus and I'm using Logic supply canbus cape. I don't see any message using candump and can't send any message. I use Microchip can analyzer to send can signals to my BBB. When I try to enable both "BB-CAN1" and "cape-CBB-Serial:r01", BBB doesn't let me to have them both activated at the same time and mentions P9.24 conflict.
How should I solve this issue? Thanks in advance.
