S32K344 CAN communication

[Voledi]

Hi NXP team,

I am trying to change FlexCAN_Ip_Example_S32K344 (in loopback mode) to work in normal mode.

In this case I do not care about Transceivers, only care about configuring CAN0_Tx, CAN0_Rx pins to work properly by connecting CAN0_Tx pin to Logic Analyzer, and also connecting CAN0_Tx and CAN0_Rx together---> The result is that I do not see any digital signal from Tx pin to Logic Analyzer, and Rxbuffer is also empty:
below is my change:

please give me help, thanks
