efm8

Flash via AN945: EFM8 Factory Bootloader HID.

Usage

Communication is over USB-HID. This is implemented via the hidapi pthon wrapper for the hidapi native library.

On linux you can use udev to grant access:

echo 'SUBSYSTEM=="usb", ATTRS{idVendor}=="10c4", MODE="0666"' | sudo tee /etc/udev/rules.d/70-silabs.rules
udevadm trigger

efm8 firmware.hex

Also includes an example that resets a https://u2fzero.com/ into the bootloader and flashes in one command.

u2fzero firmware.hex

And a way to (slowly) read the firmware back

efm8_read firmware.hex
