AM62L: MMCSD boot mode may be unable to boot from SD cards in Advisory i2464

Part Number: AM62L

Tool/software:

Why is it that MMCSD boot mode may be unable to boot from SD cards in Advisory i2464?

The workaround is to add "-a" argument to the mkfs.vfat command. This option disables to align the data structures to cluster size.

linux.die.net/.../mkfs.vfat

Why is it required to disable alignment?

Some SD cards can boot successfully even without the "-a" argument.

Should the "-a" argument always be used for all SD cards?

The "-a" argument also appears to be effective for devices other than AM62L, such as AM335x.

Our customer is using AM335x, AM64x, and AM69x with PSDK Linux.

Should the "-a" argument always be used for other devices as well?
