Debug and old IRQ

[Fabien Comte]

Hello, When I restart my application with debugger, i have strange IRQs called (TWI, ...) before init. Possibly IRQ still active and debug don't touch them.

Can I disable all IRQ on restart ? Is there a magic cleaning function ? :-)

Hi,

   __disable_irq();

I think this is ARM CMSIS funtion and it will disable all IRQ. This should be ok as you are doing it before enabling softdevice.

I did that because when a peripheral is working and debugger restart application you get some unexpected irq (end of started DMA xfer) and application crash. With that lines, no more issue, debug by nRF52 DK is stable in my case.
