CAN communication issue

[parvathy.r]

I want to do CAN testing using PXI-8512 for S32K566 MCU board.1st step i try to do is that, I took CAN loopback test from NI example finder and executed and also checked the signals using Saleae. I connected CANH pin of port 1 to CANH pin of port 2. Similarly for CANL and GND by referring the image(shown below).  I'm getting CAN error frames and in the block diagram, the array size is always zero in the reading part. I'll upload the block diagram, front panel and saleae screenshots. Please analyse those and let me know where is the issue.

Thank you
