ESP32 phy_init partition has no size

Question

I want to flash the ESP32-D0WDQ6 chip, but the code will not run. In the monitor I can see that the app actually never loads. The partition phy_init does not seem to have any size and the chip gets stuck after that line.

Monitor output:

My partition table:

Flash command:

Answer 1

I actually found a solution to the problem:

This is the WiFi NINA W102 module, which has only 2MB of storage. The problem to it crashing was just another one: To keep the NINA running, the RESET pin has to be pulled high all time. The Arduino script pulls it low after some time by itself so keeping it pulled high when the code should be executed did the trick. There is still crashed but downgrading to a stable IDF version resolved every issue.
