debug with multilink is ok，but fail after re-powerup

The K396 board I developed can be successfully pinged from my computer when running either the lwip_baremetal_s32k396 or lwip_FreeRTOS_s32k396 project using the Multilink debugger. However, after a power cycle, neither project can be pinged.

After changing the optimization level to none for the lwip_baremetal_s32k396 project, it can be pinged successfully without using the debugger. But for the lwip_FreeRTOS_s32k396 project, even after setting optimization to none, it still cannot be pinged without the debugger.

I added code to toggle an LED in vApplicationIdleHook, and it appears that the idle task is not being entered. What could be causing this issue?

Just comment out PIT and that's fine. Thanks.

Hello @zhangzhixing ,

I experienced the same symptoms. Have you tried to disable PIT in device_init, as I mentioned in my update Solved: lwip_FreeRTOS_s32k396' example project and failure - NXP Community ?

Best regards,
