I have about 6 Teens 4.1, each installed in its custom board. I am using the FlexCanT4 library along with a CAN interface board.
I noticed that on 4 Teensy boards, the software is not reporting a connection on the CAN interface. I thought the CAN interface board may be defective, but swapping that board did not help.
Some of the Teensy 4.1 modules were bought from Amazon as I needed them quickly. Could it be that these boards are knockoffs? How can one check?
Is there a way to debug where the problem might be (on the Teensy or on CAN board) given that the software is definitely working?
