Hi,

I have succefully flashed my new outdoor accesspoint using the images for the Allnet ALL0258N. Sofar everything seems to work great!
I couldn't get the Engenius firmware update to work. There seems to be some kind of validity check, also it is a tar.gz file with seperate kernel,rootfs and script in the file.
Luckily there is a serial port inside on a header for easy access. Using a 3.3v serial USB @115.2k I had access to the bootloader. Below the snippet I used to flash this great device.

#erase rootfs partition
erase 0x9F150000 0x9F66FFFF
#load rootfs
tftpboot 0x81000000 openwrt-ar71xx-generic-all0258n-rootfs-squashfs.bin
#copy to flash
cp.b 0x81000000 0x9F150000 0x1e0000

#erase kernel partition
erase 0x9f050000 0x9f14FFFF
#download kerlen image
tftpboot 0x81000000 openwrt-ar71xx-generic-all0258n-kernel.bin
#write kernel
cp.b 0x81000000 0x9f050000 0xf0000
#boot kernel
bootm 0x9f050000

Still not working. The bootloaded fails validation and refuses to boot and boots failsave. My ugly fix:

#disable validation, replace failsave boot
failsafe_boot=bootm 0x9f050000
saveenv

Cheers,

Jeroen
