There is apparently an issue with trying to use the JLink from a Nordic NRF52840 DK board to debug the NRF52840 Feather in Platform I/O. When running in debug the code hangs at NVIC_SetPriority in core_cm4.
There is a workaround documented here https://community.platformio.org/t/hang ... gger/12181
This worked for me but is not really a great solution. This does not happen when debugging the NRF52840 on the DK board. Is there maybe a better fix for this?

Same results using a Segger JLink EDU V9.

Also getting this with J-Link edu. Looks like people have had success by running without the bootloader, so the issue may be related to the bootloader.
