Hello I'm brand new to MPLAB, I'm working on a PIC32SG Curiosity Ultra and all I'm trying to do is to make blink the LED1 of the board (port PB25).
All I did was creating a new project, adding a timer TCC0 to the project and allocating it to the non secure area, generating the different files through Harmony and modifying the main.c from the non secure area to allow the led to blink.

Now when I try to build and load the program on my board, the build fails with this error:


After looking through different explanations found on the net, I still don't understand why I get those errors...
I don't modify that much the files, all I do is to generate them with harmony.

Can someone give me help of some sort?
Many thanks

 

Show us the blink-led program source.

Look at the generated source for what TCOO expects as a interrupt handler.

Untested (on real hardware) as I don't have that processor handy but it was generated and compiles without errors.
