Actually it's not impossible. PB6/SWDIO goes to X4 the expansion connector, so it's free. PB7/SWCLK goes to RST on the LCD connector, so you could cut that trace and connect to it. The LCD may not need the reset signal, but if it does you could add a push button. You would need to modify the startup code not to program the bus matrix to use those pins as GPIO.

But I've never had to resort to a debugger when developing PanelDue code.

I was considering that as well, but i'm a bit hesitant about modifying the PCB by cutting traces.

But this helped! Thanks

I'm having a hard time to find any schematics for PanelDue 5i.

Havent seen, but I can't image they're very different to the v3 board https://raw.githubusercontent.com/dc42/PanelDue/master/PCB/V3.0/PaneDue-3.0-schematic.png

Between the code and the board should be doable to work out any major differences if any.

The schematic for the SAM4S part of the PanelDue 5i and 7i is identical to the non-integrated version.

Thank you for the info. I checked the schematic, and its not possible to connect a JTAG or SWD debugger to the microcontroller since the needed pins are also connected to the LCD.

@bearer and @JoergS5 i'm also looking for a way to debug the firmware while running it on the LCD. I'm having a hard time to find any schematics for PanelDue 5i.
Any pointers to where i could find those?

With a schematic i can figure out how to connect a debugger to the screen.
