1 week ago Running "rpi-eeprom-config --edit" won't update the bootloader on a CM4 / CM4-S unless CM4_ENABLE_RPI_EEPROM_UPDATE is set to 1 in /etc/default/rpi-eeprom-update.
The recommended way to modify the bootloader on CM4 / CM4-S is via rpiboot - see https://github.com/raspberrypi/usbboot/tree/master/recovery
This is because CM4/CM4-S cannot loader recovery.bin from the SD/EMMC.
Please could you try the rpiboot approach to see if that works for you.
Describe the bug
I've been trying to disable boot from USB so that the rpi does not start in USB mass storage mode. When using the rpi-eeprom-config to edit the config file it does not seem to have the desired effect on BOOT_ORDER= [no combination seems to work or affect the system]
Steps to reproduce the behaviour
To disable USB boot on your Raspberry Pi using rpi-eeprom-config, you need to modify the EEPROM configuration. Here are the steps:
Edit the EEPROM Configuration: Open a terminal on your Raspberry Pi and run the following command to edit the EEPROM configuration: sudo rpi-eeprom-config --edit
Modify the Boot Order: In the editor that opens, look for the BOOT_ORDER parameter. You need to set it to a value that excludes USB boot. For example, setting it to 0xf41 will prioritize SD card boot and exclude USB boot: BOOT_ORDER=0xf21
Save and Exit: Save the changes and exit the editor. The exact method to save and exit depends on the text editor you are using (e.g., Ctrl+X followed by Y and Enter for nano). Apply the Changes: After saving the changes, reboot your Raspberry Pi to apply the new boot order: sudo reboot This should disable USB boot and prioritize booting from the SD card.
