Silly question, is there any requirement that partition block count must be
even for boot partition?
For instance, I'm not able to boot using this partition layout, keep getting
CCC on serial console:
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 2048 22526 10239+ c W95 FAT32 (LBA)
/dev/mmcblk0p2 22528 116735 47104 83 Linux
This one, almost works (u-boot runs, init fails mounting rootfs):
evice Boot Start End Blocks Id System
/dev/mmcblk0p1 * 2048 22527 10240 c W95 FAT32 (LBA)
/dev/mmcblk0p2 22528 116735 47104 83 Linux
