Using the STM32L412 I use the PB4 for the signal NJTRST of debug connector and the ST-LINK does not work fine (but it works using J-LINK). We use also H723, H743, L476 and L496 connecting NRST to debug connector. This can be done with L412?Best Reg...

With the SW generated by MX as example I have a timer that seems to work, but not a signal on PC7.
