Welcome to Hell.

Installation instructions

No need to clone this repo manually. You'll just need to install the Rust toolchain.

# All OSes
cargo install --git https://git.zumepro.cz/michal.prochazka/tulflash

Flashing Intel HEX binaries

# Linux
tulflash --port /dev/ttyUSBx write <path-to-hex>

# macOS
tulflash --port /dev/tty.usbserial-xxx write <path-to-hex>

# Wokňous
tulflash --port COMx write <path-to-hex>

If the flash fails, try to add --slow before the --port argument (should not be needed though).

The tool also allows reading and erasing the chip, figure that out on your own if you need that (although tulflash --help might guide you if you ask it nicely).
