Would like to reopen this topic as before it was i.m.h.o. incorrectly answered with 'no' because of supposed 32MB RAM.
But the HP version of this device actually comes with 64 MB of RAM, 8M Flash, and a SoC AR9342 v2.
It can work with current OpenWrt compiled for ath79 / nanostation-loco-M-XW firmware.
That is the answer: run Nanostation loco-M-XW firmware on it. It is the same hardware platform, in a dish antenna form factor.
The wiki may need to have this added.
There are some old dish models with the XM platform-- which is an AR7241 CPU with 32 MB RAM. These use the Nanostation XM Loco build, with the 32 M limitation.
