Thank you for the pointers, that was helpful. Copying all the mentioned .bin files to the same folder, I was able to flash it with this command: esptool.py --chip esp32 -p COM14 -b 460800 --before=default_reset --after=hard_reset write_flash --flash_mode dio --flash_freq 40m --flash_size 4MB 0x8000 ...

While in development mode, I am continuously using the command 'idf.py -p COMX flash monitor' (X=port#) at the top of my source and build tree. I would like to regularly save specific revisions, with as few files as possible, which I may at a later time flash my device with. So, what files do I mini...

Thank you for the info. I disconnected them and as you said, I can now upload SW to the WROOM. So, it means that these pins are effectively not generally available GPIOs? If that is the case, it would be great if the documentation reflects that. Then, I can upload SW to the WROOM through the UART in...

Thank you for your reply. The red wires are fixes to originally operate an RGB LED with PWM on GPIO9, GPIO10 and GPIO11. I changed that to GPIO2, GPIO4 and GPIO5, but the connections to 9, 10 and 11 weren't cut (yet). Will that affect the upload of software? Please see the attached diagram. When att...

I have trouble uploading software, for now just the 'hello_world' taken from the esp-idf examples, to an ESP32-WROOM-32 board connected my Win10 PC through ESP-Prog using either the JTAG or UART port. I would like to know if anyone has any ideas or pointers to what may be missing? I had no problems ...

Thank you for the suggestion.
I did look into that one, but it is way too heavy.

I just want the simplest and leanest way to get in characters from a keyboard and to send characters out to a display, in a terminal program like Tera Term.

I mean, playing around a bit with the uart_echo example, the following at least splits the read and write, but should make no one happy: #include <stdio.h> #include <string.h> #include "freertos/FreeRTOS.h" #include "freertos/task.h" #include "driver/uart.h" #include "driver/gpio.h" #define ECHO_TES...

I am trying to build a serial terminal on my esp32 with esp32-idf and have looked at the 'uart_echo' example. I would however like to make without an infinite while loop in a Task, but instead interrupt driven so I started look into uart_isr_register(). I would like to get one character at a time in...

I am getting the same kind of trouble, and I don't see a solution in this thread, but please correct me if I am wrong?

Best regards,
