devkit MPC5744P communication test

Hi everyone,

I used MPC5744P to test UART . I successfully download the "Hello word" example to the DEVKIT 5744P

through this MBT tool（Version 3.2)，but the Tera Term show nothing. Please tell me how to solve this problem.

BTW, the CAN commuication example also has same problem.The model is download into DEVKIT 5744P，but I can't see the CAN RX/TX( by INCA).

Hi @henryex2009,

You can change the serial port to 0 as shown in figure below, it should work.

Hello @henryex2009

Please have a look at the Schematics of the EVBs before developing your application, to make sure that the right pins are selected inside the blocks, alongside the right UART instances.
