That’s not quite the same. From what I understand of that thread, it is:
- boot eMMC Grub
- if select ‘uSD boot’ then boot uSD
Not the same as:
- attempt uSD boot first
- if fail, attempt eMMC boot
The ‘solution’ in the other thread is more of a workaround as it requires user interaction during the boot process.
Or am I misunderstanding the Attempting to dual boot - #5 by librecomputer recommendation to add boot_targets=usb mmc1 mmc0 in boot.ini file ? Does mmc1 refer to uSD and mmc0 refer to eMMC?
