Struggling to install on ESP32-S2 M1 DevKit

[Babyyoda777]

What happened?

Hi i am trying to install WLED for a project on ESP32-S2 dev kit board. I have tried everything, the various web installers just don't work. The official one gives header error whilst the unofficial one says no core dump partition found. I tried flashing myself using es32-s2 binary and esptool along side a bootloader I compiled and partition map however that also didnt work. When compiling with platformio, it doesnt have the same ESP32-S2 board Im using and when i try using saloa esp32s2 board platformio just refuses to build with error: Tool Manager: Installing espressif/toolchain-riscv32-esp @ 8.4.0+2021r2-patch2
UnknownPackageError: Could not find the package with 'espressif/toolchain-riscv32-esp @ 8.4.0+2021r2-patch2' requirements for your system 'darwin_x86_64'

Would really appreciate some help as ive become very lost. Thanks!

Hi,

Please consider that the new MCUs (-S3/-S2/-C3) are still experimental - some boards work, some don't work.

The best way is actually to compile and upload with platformIO.

You can use this build environment:
https://github.com/Aircoookie/WLED/blob/197f47befe568eef486d006aaec50b06c11c5fc4/platformio.ini#L617

• the board = doesn't need to match exactly with your board, lolin s2 mini will work with most S2 boards
• "no core dump partition found" is just a warning, you can ignore it. Also on first startup, there might be a message saying "failed to mount littleFS" - thats also normal and it will not re-appear on the next boot.
• if you struggle to find the "build & upload" in VSCode+platformIO IDE, there are some how-to screenshots here: (Doc request) compiling in platformio - selecting build envs via dropdown WLED-Docs#161
• in case you get a message that git is missing, follow the instructions to install it on your computer (https://kno.wled.ge/advanced/compiling-wled/#preparations)
• if you want to compile the 0_15 development branch, you may need to install npm manually first: https://kno.wled.ge/advanced/custom-features/#changing-web-ui

PS: there is ongoing work to make the official web installer work with more boards. For flashing manually with esptool, you can find a list of items needed in wled/WLED-WebInstaller#22 (comment)

Thanks so much, I'll give it all another go!

I'm closing as installing WLED firmware is a separate topic. WLED itself works correctly on S2, S3 and C3, albeit not on every model there is.

Thanks I managed to sort it out! I created a repo with compiled binaries and instructions for installation using web gui.
