Trying to set up an rpi3 with DietPi_RPi-ARMv6-Bullseye. Flashes to micro SD card and boots. When I get to dietpi-config > Advanced Options, the USB boot support is [On]. How do I change it to [Off]?
I am running as root, so no priv issues.
Everything else on that menu page toggles with the space bar. Pressing the space bar when USB boot support is highlighed just refreshes that page without updating anything.
I assume I may have caused this problem by trying to turn on USB boot support by adding “program_usb_boot_mode=1” to the end of the /boot/config.txt file yesterday when I was trying to get USB boot working. I ran into problems. I have reflashed the micro SD card and I want to go back to micro SD card boot all the time, even when I connect an external USB HD to hold my media files.
Any suggestions how to toggle that setting in DietPi-Config > Advanced Settings?
