esptool VS PlatformIO

Next, install esptool onto your computer, then run the following commands to flash the MicroPython firmware onto the ESP32C3 using the bin file you've just downloaded.

Is the flash download tool in the image the gui for https://github.com/espressif/esptool/releases ? Or is there somewhere I can download the source? Need to automate the download process

GPL TL;DR: - The Skymap is still Stellarium Web Engine, AGPL covered code. - The motor controller is an Espresso board of some type, as evidenced by the main_S50_1.4.8.bin that controls it, and the GPL covered code in /etc/zwo that pushes the code to it. (https://github.com/espressif/esptool). If the AM3/AM5 use the same architecture, that code's probably on those units as well. - libgsl was added to the Seestar and the ASIAir in 2.1. That's GPL3 code under GNU/FSF purview. - The Seestar implements opencv and the yolov5s-small model. Yolov5 is AGPL-3.0

My problem like yours solved with this : https://github.com/espressif/esptool

I'm not the most knowledgable on the topic, as most of what I have done was troubleshooting esptool with weird development boards. But the programmer tool is called esptool and can be found on github. https://github.com/espressif/esptool

So after I read this - I tried to do exactly that. But the main Problem is that, the --force Option is not available within the ESPTOOL.. I use a Mac with macOS Ventura. I already created an Github-Issue here: Github. But in case anybody from this Subreddit already had this issue and give me a hint to fix that.

I just did some googling and found this thread. It's not clear to me that the people commenting know what they are talking about but there's some discussion about using hubs and modifying the esptool.py sequence. https://github.com/espressif/esptool/issues/790

Using '/dev/cu.usbmodem01' as serial port. Connecting........ Detecting chip type... Unsupported detection protocol, switching and trying again... Connecting...................................... Unexpected error: ESP Chip Auto-Detection failed: Failed to connect to Espressif device: No serial data received.

I found esptool use DTR (GPIO0) and RTS (EN) to reset.

For the ESP32 in read mode, we've successfully developed a project using PlatformIO that accepts the key during build time and stores it in memory.

Check out Zephyr OS and Platform IO. Zephyr is part of the Linux foundation and has similarities to Linux with how it performs hardware abstraction (device tree). Platform IO integrates with other frameworks including mbed and Arduino.

PlatformIO together with avr-stub can be used to do source level debugging but there are some caveats.

Look into https://platformio.org/, it can abstract over a few RTOSes, and can show you which OSes work with which chips/boards.

If the HW looks like it works, you could also try alternate programming software. (e.g. TinyGo or PlatformIO)

You might have better luck with PlatformIO than the Arduino IDE; it's better at automatically choosing the serial port, though I can't say I've used it under Windows.

My other suggestion takes more work but will make your life oh so much better. Professionally I have used and highly recommend. https://platformio.org/ which is free!

Will you be doing embedded Linux? Embedded RTOS? Bare metal? Microcontrollers? SoC (say, FPGA with a hard processor core)?

You can do a lot with QEMU. https://bootlin.com/ has a lot of great, free training material.

https://bootlin.com/doc/training/embedded-linux-qemu/embedde...

is one of my favorites.

Learning to cross-compile, do embedded debugging, the process of booting an embedded system (which varies depending on the answers to the above questions), learning how to read a technical reference for the processor you’re using as well as for peripherals you’re likely to interact with - SPI, i2c, UART, maybe PCIe, are all handy skills. Learn a bit about JTAG, hardware, reading schematics, etc. Even being able solder is helpful.

There may be books (I had a great embedded Linux book when I started) but there are lots of online materials too. Check out https://platformio.org/

There are fun embedded boards and projects for microcontrollers too - micropython on an rpi pico, tinygo, eLua, etc.
