Finally got around to test FDCAN on this board and I got Ch2 and 3 running, but found an annoying bug on ch3. This took me a while because setting up FD CAN is not straight forward, but with good help from CharGPT it finally worked.
What is remaining on this board is to modify Ethernet + wrap up SD-Card – after that I will order a new PCB and try a small production batch because this board is very handy to use.
