2. Push the Emergency Stop button.
3. Turn on the main power switch.

All base products have a screen, so you can view if it is in bootloader mode simply by checking the screen. Chassis Controller

After successfully putting the controller into bootloader mode, the screen will display the bootloader mode message.

Start flashing

Connect the type-C usb cable to the controller.

Then, run ./xrock flash write 262144 {PATH_TO_THE_EXT2_FILE} on your ubuntu computer that just compiled xrock.

MAKE SURE YOU TYPE 262144 CORRECTLY. If you type it incorrectly, you will brick the controller.
