Does anyone know if the HG659b has 3.3v TTL or jtag headers? Also processor type, wifi chipset etc... Before I try and open up a spare unit I have sitting around. I want to try and add support to the openwrt buildroot for it.
Bit of digging reveals it is using the BCM63168 chipset. But I think you'll have to crack one open to find the jtags etc. These seem like fairly capable devices, bit surprised to not find more hardware info online...
Let us know how you get on with this. Could be very interesting.
Does OpenWRT support xDSL binaries, etc? Last time I looked into it the main focus was on Ethernet based devices, and hardware with xDSL support which could run OpenWRT couldn't use the xDSL chips after being flashed.
Thanks for the info, at this stage I'll try and get it running as an Ethernet router, xdsl will be more complicated. Hoping the bootloader isn't locked down
The Huawei boxes are pretty closed and the DSL chipset drivers are most definitively closed. So in almost all situations OpenWRT isn't supported on integrated routers as it's too much of a pain to build a useful toolchain and then flash and the lack of support for the DSL chipset.
Broadcom in general isn't that well supported on OpenWRT, they prefer the Atheros WIFI chipset is better supported.
I haven't done much more with this. If you can get it to boot Linux via network you could use that to access flash or the other option failing jtag is to desolder the flash chip and attach it to a adapter for read/writing

Unfortunately when you set it to grab the image off a tftpserver it disables the switch. Basically no network boot.... :(
I guess there is no other way than reading the flash chip directly.
