The problem was the espressif32 framework version! Version 4.2.0 produces only the noise described. Version 3.2.1 and 3.3.2 work fine.

> Can you please explain how to revers to 3.2.1 in Plarformio? Just open the platformio.ini and add "@ 3.2.1" in the same line after platform = espressif32

@lidense Yes, it is based on an older version of the framework provided by Espressif. Unfortunately it's not unusual that things break when the framework changes. Sometimes new bugs are...

Ok, it seems to work by simply removing the insertion of the backslash. ``` #SRCLIBDIR:= $(subst $(space),\$(space),$(realpath lib)) SRCLIBDIR:= $(realpath lib) ```

Ok, building works fine now, as far as I can tell. I've connected the PCB with a STLinkV2 and using other software I can read the chip ID and type,...

Thank you for your reply! I found out, that OpenOCD starts, when I first change into the opendps folder and run `openocd -f interface/stlink-v2.cfg -f target/stm32f1x.cfg` It doesn't work in...

Thank you for your offer, maybe I will get back to you about that! Using `dpsctl.py` I've now completed the calibration process, but something is still off, the displayed input...

Ok, I've re-run everything with the best multimeter I have, hooked on a 2.2 (2.27 to be exact) Ohms load with 100W for measuring and successfully completed the `--calibrate` process....

@hseibel12: You're right the input voltage I entered was nonsense! I repeated the above mentioned calibration with about 6.5 V and 19 V. I additionally measured the exact value with...
