Hi cellprop,

Would you please show me the Debug view?
It should be able to show you which codes caused default isr.

I didn't meet default isr after debug your attached project.

Best Regards,
Robin

Hi cellprop,

The project that you attached is led_segger_debug, but I see you are debugging LCD_20×4_debug. I don't know if there are some difference between two projects.
I can see you initialize external 8MHz crystal in led_segger_debug, would you please check if there is sine wave on external crystal pins?

Best Regards,
Robin
