I'm dealing with several units with flash layout which slightly differs from the one in the docs. I got them second hand so can't give you more details. The year printed on the board is 2011 and the antennas are the size of a euro coin each. This thing's ancient. Here's the reported layout:
UBNT-BZ.v4.3.28# cat /proc/mtd dev: size erasesize name mtd0: 00040000 00010000 "u-boot" mtd1: 00010000 00010000 "u-boot-env" mtd2: 00760000 00010000 "kernel" mtd3: 00040000 00010000 "cfg" mtd4: 00010000 00010000 "EEPROM"
Should I flash
initramfs-kernel.bin image first and then the
squashfs-sysupgrade.bin? To be frank, I tried with the
sysupgrade first but I think I bricked one of the units.
