Problem using UART after starting a debug session (Black Magic Probe v2.0.0-rc2-dirty) #2093

adesgagne commented 2025年03月17日 20:39:05 +01:00 (Migrated from github.com)

Using the BMP firmware Black Magic Probe v2.0.0-rc2-dirty, I'm having an issue with the UART communication between two devices (nRF52832 and STM32WL5MOC) after starting a debug session.

The UART interrupt appears to stop working.

I tried to downgrade with the BMP firmware Black Magic Probe v1.10.0-1010-ga8a5a02e-dirty and I'm not having this issue.

I'm using cortex debug extension with gdb-multiarch.

Here's my launch.json file.
