Automatic MCU script update

Automatic MCU update script

Dependencies

For this script to work it assumes Katapult is flashed on each MCU because this script uses Katapult to flash the (newest) Klipper firmware onto the MCU. Read Step 7 - Flash Katapult Bootloader of the guide on how to get Katapult on the SV08 MCU's. And read this guide on how to flash Katapult on the BTT Eddy (if you happen to use Eddy).

Install

Please look at Step 8 how to prepare the script.
Short version:

• Copy the update_klipper_mcus_sv08.sh script to your ~/klipper folder.
• Edit the script and enter your device serials (the serial parts after stm32f103xe_).
• Make the script executable with sudo chmod +x ~/klipper/update_klipper_mcus_sv08.sh
• Use the script with the following command:

cd "$HOME/klipper" && ./update_klipper_mcus_sv08.sh

Troubleshooting

You might get the following error after executing the script:

/usr/bin/env: ‘bash\r’: No such file or directory

This means you have probably saved the file in Windows (with the Windows/DOS line endings) and we need to convert the line endings to Unix style. The easiest way to do this is to re-save the file with Nano:

• cd ~/klipper (Go to the Klipper folder where the script is, if you are not there yet)
• nano update_klipper_mcus_sv08.sh (Open the file with Nano)
• CTRL-O (Write Out) But do not press enter/save yet!
• ALT-D (DOS Format) You will see [DOS Format] appear or be removed in front of the filename when pressing ALT-D. Make sure there is NO [DOS Format] in front of the filename.
• Press ENTER to save (you will see a message [ Wrote xx lines ] when the file is saved)
• CTRL-X to exit.

We have now converted the wrong line endings to the correct ones and you can once again try to execute the script with:

cd "$HOME/klipper" && ./update_klipper_mcus_sv08.sh
