Flashing a new bootloader is a one time step that typically requires an external programmer - search the web to find the instructions for your particular device. + +### How do I upgrade to the latest software? + +The general way to upgrade is to ssh into the Raspberry Pi and run: + +``` +cd ~/klipper +git pull +~/klipper/scripts/install-octopi.sh +``` + +Then one can recompile and flash the micro-controller code. For +example: + +``` +sudo service klipper stop +make flash FLASH_DEVICE=/dev/ttyACM0 +sudo service klipper start +``` + +However, it's often the case that only the host software changes. In +this case, one can update and restart just the host software with: + +``` +cd ~/klipper +git pull +sudo service klipper restart +``` + +If after using this shortcut the software warns about needing to +reflash the micro-controller or some other unusual error occurs, then +follow the full upgrade steps outlined above. Note that the RESTART +and FIRMWARE_RESTART g-code commands do not load new software - the +above "sudo service klipper restart" and "make flash" commands are +needed for a software change to take effect. |
