built-in jtag down after esp_wifi_start
Posted: Sat Dec 10, 2022 11:39 am
Is it expected that the built-in jtag goes down after esp_wifi_start is called?
In my software the debugging works fine until that point. I can also step into esp_wifi_start, but going over it without breakpoint breaks the USB jtag connection. Stopping at esp_wifi_start seems to break the timing of the function.
This is when setting a breakpoint on esp_wifi_start:

Any ideas? Is it possible to use builtin-JTAG with WiFi?
