Flashing the firmware

You will need rust installed so:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

cargo-binutils for stripping unused data from the rust binary and other optimizations:

rustup component add llvm-tools
cargo install cargo-binutils

dfu-util for flashing:

sudo pacman -S dfu-util

add the rust target for the MCU:

rustup target add thumbv7em-none-eabihf

then to compile the firmware:

cargo objcopy --bin yuki --release -- -O binary yuki.bin

for the right board add --features right

to flash enter dfu by holding BOOT clicking RESET and releasing BOOT and enter:

dfu-util -d 0483:df11 -a 0 --dfuse-address 0x08000000:leave -D yuki.bin"

After that to enter dfu just hold button 05 and 33 click reset and release the buttons.
