OK, found the problem. A mistake at my end.
I had connected the led to the cmd pin instead of GND (that small writing on the board is hard to read). It is no surprise that the led was flickering.

Use GPIO12, 13, 14, 15 as "normal" IOs
Hi I known that the ESP32 uses the GPIOs12, 13, 14, 15 for JTAG and that it is possible to configure them as "normal" IOs (mainly as outputs), but no matter what I try I dont succed reconfiguring those pins. I have tried to use the methods below (for pin 14), but also other hints I found on the web....
