Easy ESP32 flashing!

Just to let you know I added the ESP32 web flasher to the Espruino website so you can now easily install the ESP32 firmware.

https://www.espruino.com/Espressif+Flash

It should work on ESP32/ESP32C3/ESP32S3 and ESP8266 - but I've only added ESP32C3 builds since 2v25.

The tools used are these ones: https://esphome.github.io/esp-web-tools/

2v25 seems not to support ESP32C3 as far as I can see
Your ESP32-C3 board is not supported.

Anyone had success flashing a C3?

Ahh, sorry - just checked and the manifest file was missing a hyphen so it wanted ESP32-C3 and not ESP32C3

Just tweaked it and it works now - you'll have to make sure you refresh the page so https://www.espruino.com/binaries/espruino_2v25_espressif_manifest.json picks up the correct hyphenation

Any hope that ESP32-C6 will be added too?
Tried today (selecting "Espruino 2v25") but:
Your ESP32-C6 board is not supported :(

[gfwilliams]

I'm afraid we don't have builds for the C6 yet. I could be wrong but I think that the C6 isn't supported by ESP32 IDF4 (we'd need to move to 5) and while some folks have looked at it, Espressif changed some things (mainly the network handling) that I think would require a rewrite of that part of Espruino for us to upgrade

Thx for your answer! Sounds like it will take some time before an upgrade will be available.
So I have to be patient - or try Espruino with another board in the meantime because I really like the idea to use JavaScript on a microcontroller!
