fix: stlink-v2-isol needs re-enumeration #2266

hrm commented 2026年05月27日 19:13:06 +02:00

if we use the stock bootloader, we need to PULL PA12 to GND

Detailed description

This was overlooked from my side when doing the original PR, because I used the BMD bootloader which managed to trigger re-enumeration. However when I flashed stock unmodified probe, it appeared to be stuck in bootloader mode because of the missing re-enumeration.

I will now push a second commit as a proposal. The idea is to set PA12 low at boot regardless of the platform. I believe this will make things simpler and more robust
