Adding OpenWrt support for ZyXEL SBG3300-N

I have one of these devices lying and am looking for any help on getting openwrt on it.
I've googled it but can't find much help on building an image for it.
I don't care about the VDSL/ADSL modem in it, and I know its not supported.
So can anyone give me any hints on if its possible and/or how to build an image for this device?

Thanks Jim

The "firehose" is

Not much on

  • ZyXEL SBG3300-N Series - Wireless N VDSL2 Combo WAN Small Business Security Gateway
    ZyXEL SBG3300-N - Broadcom BCM6368 chipset (G.INP)

Not a chip I know off the top of my head, but Broadcom wireless is always a problem as it effectively doesn't support open-source projects. (Broadcom "CPUs" are not always so much of an issue.)

Several devices in varying states of OpenWrt support listed at[CPU*~]=BCM6368

Most of them look to have a 400 MHz MIPS core, which is pretty underpowered these days. The 750 MHz class, MIPS-based processors in "last-generation", all-in-one routers can barely handle a couple hundred Mbps, so this SoC is probably half of that (even though dual-core), though in keeping with its 100 Mbps Ethernet.

I would find it hard to justify the time myself, given that one can now buy a good-quality all-in-one starting at US$20 or so. It might be an interesting "project", but if that's what you're after, I'd recommend a more current, perhaps better documented device.

Yeah, when I found soo little information on this devices hardware, let alone on its openwrt compatibility, I thought it was a long shot.
But there's a fair bit of information on its processor and openwrt;
which is why I thought I'd ask.
But its just because I have this device lying around doing nothing that I thought I'd look into it. I have little programming knowledge though.
