FAT partition for Kernel image imx8m Mini

[antonio_santagi]

Hello,

by default the Linux BSP for imx8m mini creates a FAT partition, separated from RootFS partition, that comprises the Kernel image.

What is the reason why this is a better solution than having a RootFS partition with the Kernel image in it and no FAT partition at all ?

Is it because in the case of corrupted RootFS then Kernel at least will be loaded and can try recovering the RootFS ?

thank you

Recently u-boot did not support ext2/ext3/ext4 filesystems and one was forced to place the kernel on FAT (or directly on the drive, outside of the filesystem).
Also you can access device tree from windows machine if you attach the card with a cardreader.

However I suppose there is no strong reason to have this FAT partition instead of using rootfs.
But it if still recommended.
