So I am guessing it is all on the uart\usb chipset. Like a built-in feature than comes with IC No, some additional circuitry is added (where WiFive mentions, look for the label on the PCB itself) to coordinate the automatic reset. You can read about the details here: https://github.com/espressif/es...

There's some more information about this boot output on the esptool wiki:

To reach this I think it will be needed not to run FreeRTOS (scheduler takes some time), write my own drivers (even with FreeRTOS I had to use custom driver for MCPWM) and optimize FPU. I don't want to discourage you from going your own way, but for what it's worth if you only have a single task ru...

Hi Jason,

That's not something we'd expect. What clock speed are you running the PSRAM at (config item)? And what ESP-IDF version are you using?

Recent ESP-IDF fixed some issues running PSRAM at 80MHz, where signal quality could be borderline in some cases.

Hi funnygiraffe, I've moved this topic the Arduino forum as you're using Arduino. If using Arduino isn't a requirement then I can move it back. The last parameter of WiFi.scanNetworks() function is "uint32_t max_ms_per_chan = 300", which is the amount of time to spend listening on each channel as pa...

Hi yanosz, /home/esp32/JellingStone/main/./main.c:69:77: error: implicit declaration of function 'esp_err_to_name' [-Werror=implicit-function-declaration] The esp_err_to_name() function was added to esp_err.h after IDF v3.0 was released. It's new in v3.1. You can solve this error by switching to the...

Hi murugesh,

The Getting Started guide steps for Fedora should be very similar to the CentOS steps in the Getting Started guide:

If you notice anything which is different, please let us know.

Hi jpan27, If MSYS2 is the main sticking point then you might want to take a look at the CMake-based build system (currently in preview release) which doesn't require MSYS2: https://esp32.com/viewtopic.php?f=13&t=5559&p=24109 selectively compile what I need from the IDF framework into a static libra...

Thank you very much for such an exhausting answer, I really appreciate that. I am interested in building quadcopters based on ESP32 and its followers. I have successfully built a flying quad with ESP-IDF but it seems to me too heavy for this. I would like to build a custom lightweigth SDK (without ...

That's right, whenever software asks for a pin number it is asking for the GPIO number not the number of the pin/pad on the QFN package. So, for example, the default UART 0 TXD pin is GPIO 1. You can find it at pad 41 on the ESP32-D0 QFN package (a different pad on the ESP32-D2, but it's still GPIO ...
