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 still do not understand why the chip is bricked? debugger accessing chip from SWD is a different thing. I think there is a reset happening at the early phase of your startup, so your chip is in infinite loop of reset.
