Installing OpenWrt on Aerohive HiveAP 330

I am following a tutorial to tftp boot a HiveAP 330. All goes well until I run sysupgrade. Then upon reboot, I get the error

GUNZIP: uncompress, out-of-mem or overwrite error - must RESET board to recover
   Loading Ramdisk to 10000000, end 10000000 ... OK
   Loading Device Tree to 00ffa000, end 00fffd9a ... OK
ft_fixup_l2cache: FDT_ERR_NOTFOUND

Any assistance would be greatly appreciated. Tutorial is https://massmesh.org/wiki/index.php?title=Aerohive_AP330

Cheers,

What file are you using for the last step ?

openwrt-mpc85xx-p1020-aerohive_hiveap-330-squashfs-sysupgrade.bin

Cheers,

Try using something older, as described in https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=f2b7d9dc1ca3d33f14961cf2885639f4f9e8965e

Does the same happen when you try to install 21.02.1 instead of snapshot?

I have similar error on custom snapshot build (december 21).
On 21.02.1 stable version work great.
