Good day! I have a device with Raspberry Pi CM3+ and Debian 10 pre-installed in eMMC. I want to try changing the OS to something else. I have already tried changing /boot/config.txt by adding "program_usb_boot_mode=1", but it did not work. I do not have a debugging board for CM3+ that I could simply connect to my computer. Do you have any advice? I have no more ideas except for directly erasing/rewriting eMMC.
