Automatic MCU script update

Automatic MCU update script

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
