Hi,

You debugger scripts place IP on _Start label.

This is why it is working correctly on first load.

Your code behaves correctly. After reset it is set to Address in your RCHW.

Which is 0x40314.

Set RCHW to correct start address where your _start label is located and it will work correctly after any reset.

regards,

Peter
