nanoFirmwareFlasher attempt to add ESP32-C3 support

[lsd-techno]

Good evening.
I've attempt to test nanoframework on ESP-C3-32S module based board.

First when I try to identify board I got error that bootloader not found:

PS C:\nanoff> .\nanoff.exe --serialport COM4 --devicedetails
.NET nanoFramework Firmware Flasher v2.0.9+947a088d7c
Copyright (C) 2019 .NET Foundation and nanoFramework project contributors


Using COM4 @ 1500000 baud to connect to ESP32.
Reading details from chip...
Unhandled exception. nanoFramework.Tools.FirmwareFlasher.WriteEsp32FlashException:

PS C:\nanoff>

so the error is "esp32c3bootloader" and content not exist:

esptool write_flash: error: argument <address> <filename>: [Errno 2] No such file or directory: 'C:\\nanoff\\.store\\nanoff\\2.0.9\\nanoff\\2.0.9\\tools\\net6.0\\any\\esp32c3bootloader\\bootloader.bin'

Next I try to get bootloader and other files from esptool repo but finished with different file naming and suspect there may be more difference.

Is there any documented way on how to add new ESP32 hardware/chip support?

This is what I able to read with esptool:

@lsd-techno support for ESP32_C3 it's a work in progress.

[lanmark7]

Is it still a work in progress?

[josesimoes]

Yes it is...
