# Partitioning description
from: https://forum.openwrt.org/viewtopic.php?id=41449
Art partition for 16MB Flash :
16MB total size in hex = 1000000
64kb art partition size in hex = 10000
Art partition hex address = 1000000 - 10000 = FF0000
64KiB uboot + 64KiB data (PIN&MAC) + kernel&fs + empty space as needed + 64KiB
ART at the end of flash, in total the size of your flash. The maximum size of
kernel&fs is the size or your flash, minus 128KiB uboot+data, minus 64KiB ART.
Data & ART blocks are from backups of that same router.
