Select petalinux-config -->Image Packaging Configuration ---> jffs2 erase block size(KByte) (jffs2 erase block size: 128KiB)
Note: 8KiB erase block size does not work with 5.10 kernel because they disabled the dependent kernel configs to support UBIFS boot support. - Set Primary Flash as boot device and boot images storage. For more information, see Boot Images Storage Configuration and Primary Flash Partition Configuration.
