TC367, ADSV1.8, 5v-TFT EVB: SW can work with debugger on, but can't run without debug

[zhouyi_NJ]

Hi, Infineon expert:

The environment is TC367 ADSV1.8   TC367-5V-TFT EVB. 

DFlash writing test code and  STM ISR are added ,   LED is toggled cyclically with STM ISR.

The strange behavior is :

1) if enable DFalsh writing ,  the SW can run correctly after start debugger and keep debugger activated. The DFlash is also written correctly.

2) if un-plug the USB cable, then plug on,  the SW can't run ( LED doesn't toggle)

3) if remove the DFlash writing code, the LED can toggle with debugger activated or without debugger 

Could you please give me some hint what is the conflict?

The whole project is attached 

thanks and BR

Hi ZY, I suggest to start from this example code: https://github.com/Infineon/AURIX_code_examples/blob/master/code_examples/Flash_Programming_1_KIT_TC...

And then migrated to your project.

Hi, dw:

thank you very much. 

But, my DFlash erasing/writing code is copied from that GitHub example. 

thanks and BR
