Part Number: AM5728
Tool/software: Linux
Using a am572x_gp_evm_REV_A3a evaluation module with the display panel detached. According to the schematics the connector P17
has DCAN1_RX and DCAN1_TX accessible on pins 20 and 50 respectively. Running the stock Linux kernel but I seem to be unable to
get the can device to be recognized by the kernel. Not sure what I am missing.
