Referrence test with Kvaser
Install Linux software for Kvaser CAN FD, use it to generate several custom CAN Frames with different protocol options such as: Normal, FD, RTR, NO RTR, frame with 15,17,21 bit CRC, with BRS , without BRS. Sample the final bit sequence by logic analyzer, store it to file, and implement test which will transmitt the same CAN Frames as the one transmitted by Kvaser, and compare the bit values with Bit values from Kvaser.
Note that this test should provide some basic level testing with reference controller in simulation!
