Even if you work on something else (like the RPi) it might be worthwhile to continue on this particular project as well, so will try to answer more questions. I’m not sitting there to experiment, so it is more difficult to know what to do next without some possibly (probably?) confusing explanations.
In your file “/boot/extlinux/extlinux.conf”, do you see the word “quiet” as part of the “APPEND” line? If so, then remove the word “quiet”. Any editor will work. To see what is in the file without opening an editor you can “cat /boot/extlinux/extlinux.conf”. When editing your editor must be started as user root, which is done by prefixing “sudo” to the editor start command.
Regarding this:
…does this mean that after modifying that file you rebooted again and the change persisted? Changes should revert and go away after a reboot. However, you said “T H I S D O E S N O T W O R K”, so it sounds like the changes were permanent.
The SD card model uses “/dev/mmcblk0” since it doesn’t have eMMC and enumeration starts at 0. If this were an eMMC model, then the SD would be bumped to “/dev/mmcblk1”. It can be hard to always name the correct one when replying to many posts where people might have either model of Nano, so beware the “1” or “0” might be off in posts speaking of a different model. Summary:
- For SD card models use “
/dev/mmcblk0”, - for eMMC models the SD card is instead “
/dev/mmcblk1”.*. - The first partition appends “
p1” to themmcblk#.
