How to support IRQ in bootloader?

[Jeffrey Haynes]

Is there any good way of supporting a button interrupt in a bootloader or is this a “bad idea”?

im afraid I have to add SoftDevice support to the bootloader and I’m not even sure if that’s practical. 

I’m using nrf52840 with SDK 15.0

Hi Jeff, 

are you using our Secure Bootloader example in the nRF5 SDK or are you creating a custom bootloader. Either way, I do not see any issues with adding support for a button interrupt in the bootloader code.

Adding a pin change interrupt in the bootloader should be easy to implement, I recommend that you use the Pin Change Interrupt Example in our SDK as a reference. 

Best regards
