Hello. I'm trying to replace some CS3 interrupt handlers with mine.
I'm already implement SysTick handler
extern "C" void __cs3_isr_systick() { ... }
and it's works well.
Then I try to implement GPIO Port M handler
extern "C" void __cs3_isr_GPIOM() { ... }
but then interrupt occurs default CS3 handler executed.
What I'm doing wrong?
