Host Machine Burn Tutorial

1. Install the flashing tool

   • Only execute this for the first flashing, no need to run it again after that

   cd ~/klipper/lib/rp2040_flash/ && make
   

2. Execute the following command to check if the connection is successful.

   • Enter lsusb

   • If there is no 2e8a:0003 device, please try to re-enter flashing mode

   • Due to system version issues, it may display other names. If there is a 2e8a:0003, it indicates that the flashing mode has been entered.

     
   Note

   Only proceed if there is a 2e8a:0003.

3. Pull the pre-compiled firmware
