# Prebuild
1. Download image from
2. todo something espflash tool here

# From source
## Preconditions
* rustup with current version
* espup with current version
* npm /npx
* Connect the board via usb to the computer
* Ensure the esp is running (eg not in deepsleep if prior version was installed)
# Compiling and uploading
1. Clone the gitea 
2. go to the rust/src_webroot
3. npm -i
4. cd ..
5. cargo run

Depending on the setup of the cargo runner, either a OTA image is build or the firmware is directly flashed to the esp.

Note: If the bootloader is currently booting from ota_2, flashing ota_1 via usb will not make it switch. You might need to manually erase it in this case prior.
