Hi,

Kind of a stupid question, but I can seem to find why this doesn't work.

I am using a S32K144W. When debugging everything works fine and I can develop my application. However, when I disconnect the debugger (JLink) and power cycle my board, nothing happens. Pressing the reset button doesn't work. The application doesn't start.

When I attach my debugger and start the gdb server, the application does run when pressing the reset button.

Can you provide any pointer to why this is and how to solve this problem?

Thanks!

Hi @Senlent ,

Thanks for your reply.

After some more testing the issue seemed to be the fact that I went to VLPS power mode. No idea why it works when the debugging is connected.

Hi@peacefulcarrot

I have encountered some similar problems, and the reason for the failure was that the clock did not run

properly.You can check if there is any problem with the clock configuration
