no idea, someone?

Hi, I am looking for a way to modify the ``uart_config_t`` data for a Serial that is given to my library by the user application. I need to adjust buffer sizes and install an ``onReceive`` callback for it. My idea was to read the configuration data from the running Serial, stop it and start it again...

You could burn the eFuse in the ESP32 to indicate it should ignore that bootstrap pin and just use a set voltage. espefuse.py has an easy option for that, suggest you look that up if you want to go that route.

Thanks, I will have a look at it.

Just in case someone will encounter the same issue, here's the solution: The ESP-prog JTAG line "TDI" is configured on GPIO12. So with the JTAG connected GPIO12 gets a defined logic level on boot from the ESP-prog. Unfortunately, on boot the GPIO12 line is controlling the flash voltage and with my b...

Other ideas, anyone? I am at a loss here. [Update] I definitely can sort out power issues (brownouts or such). I now am powering the setup with my lab PSU, both 3.3V and 5V rails may suck up to 1.5A without voltage drop. The complete setup is using a mere 0.5 watts as seen on the PSU, startup curren...

Faulty button could be point here I think I have simmiliar thing

But should not touching EN with a GND wire work in that case?

Nothing different, unfortunately.

I have been skimming the net in the past days to find a solution to my issue to no avail. I got an ESP32 DevkitC V4 board for development that ran for months without any problem. But some weeks ago it started to not boot properly on RESET pressed, but fell into the notorious rst:0x10 (RTCWDT_RTC_RES...

Any idea, anyone? Or does no one use the loopback IF at all?
