problem with S32K144EVB board

Hello, a few days ago, I use two S32K144EVB boards to run the demo of CAN communication (can_pal_s32k144) and a CAN based bootloader demo. The result was ok.

When I try to run the same CAN communicaiton demo today, I encounter a strange problem. The LED D1 turns to red after reset. D1 is in the red square in the following picture.

I can debug the software through the opensda, the software can run in the debug environment. But when I leave the debug mode, the D1 led turns to red immediately.

I think that the mcu is always been reset when power of, so the program has no chance to run. I have no idea about how to deal with the problem, please help.
