SK-AM62A-LP: [sk-am62a-lp][MCAN_LoopBack][R5ss0][No RTOS][MCU+SDK 10.00.00.14] Couldn't see any data on tx and rx pins for MCU MCAN0 and MCAN1

Part Number: SK-AM62A-LP

Tool/software:

Hello all, 

I am trying to test MCAN driver for R5 core therefore I have compiled this example: mcan_loopback_interrupt_am62ax-sk_mcu-r5fss0-0_nortos_ti-arm-clang.

this example use MCU_MCAN1 for sending 1 message kindly check the configuration: 

and I could see this output on serial: 

but when I have connected the logical analyzer to the TX and RX pins for MCAN1 I couldn't see any data on them:

Additionally I have tried to change the used CAN channel to be MCU_MCAN0 and while sniffing on the MCAN TX and RX pins I couldn't see any data also.
could anyone support in to identify why I couldn't see any data on CAN TX and Rx pins ?
