Google Fiber Box GFRG200

For Developers

Hello OpenWRT developers and Hardware Hackers!
I have a Google Fiber Box GFRG200, a gigabit router that is very common and cheap as Google no longer supports them, or at least doesn't give them out anymore. I have been looking to get OpenWRT on one of these for a while now, but I am just absolutely stumped. I am very amateur when it comes to this, so some help would be appreciated.

The PCB has a UART header which I am able to connect to and get some basic information from the device, but sadly no shell and no way to stop the boot sequence from what I can tell. The device has, if I typed in the NAND chip's serial correctly, 16Gb of flash, and 512MB of RAM. I will attach the bootlog, but basically all I can see is uloader loading Barebox, which then loads the linux kernel but the autoboot timeout is set to 0 so it's not possible to override this. When it has booted it says it needs either debug=1 or login=1 in the linux commandline, but I can't modify it without stopping the boot process, which I can't do because of the autoboot timeout.

I have little experience in embeded devices and would love to get into it but this is absolutely stumping me still, any help or response would be appreciated!!

The boot log is included in a pastebin as the whole thing was too long for the forum post.

edit was to add pastebin link

There is no SOC support for Comcerto Mindspeed c2000, neither in OpenWrt, not mainline linux. This means you'd not 'just' have to add a new device to an existing target, but would have to start with SOC- and driver support first (and also for mainline). That is 'possible', but a lot harder - and realistically not very likely.

Ah, thanks for the info on this. Unfortunate but still helpful. Maybe I can still do something with this thing
