This file describe How to update manually the partition of SDCARD:
1. SDCARD schema of partition
2. How to populate each partition
3. How to update the kernel/devicetree

1. SDCARD schema of partition:
------------------------------

EOF
print_shema_on_infofile

cat >> $FLASHLAYOUT_infoname  << EOF

2. How to populate each partition
---------------------------------
EOF

print_populate_on_infofile

cat >> $FLASHLAYOUT_infoname  << EOF

3. How to update the kernel/devicetree
--------------------------------------
The kernel and devicetree are present on "bootfs" partition.
To change kernel and devicetree, you can copy the file on this partitions:
- plug SDCARD on your PC
- copy kernel uImage on SDCARD
   sudo cp uImage /media/\$USER/bootfs/
- copy devicetree uImage on SDCARD
   sudo cp stm32mp1*.dtb /media/\$USER/bootfs/
- umount partitions of SDCARD
   sudo umount /media/\$USER/bootfs/
   (dont't forget to umount the other partitions of SDCARD:
