Boot: ROM is unable to boot from SD cards with incorrect formatting
MMCSD boot mode may be unable to boot from SD cards if the filesystem is formatted incorrectly during the creation of the filesystem.
When creating the SD from Ubuntu 22.04 system, add "-a" argument to the mkfs.vfat command to generate correct boot partitioning.
