Does anyone off hand know which of the strains of BCM procs are in the HG612. I've got the 3B but haven't opened it up yet. Probably project for this afternoon.

It's easy enough to rip apart the firmware to see what's needed, but I'm not quite sure (without horrid in-depth slavery) sure which one of the bunch it is. If I know, I could dig out the right toolchain from somewhere (hopefully) and see if something a little more interesting could be done

Here's a list of available BCM 96x chipsets I know of:

BCM96368MBG
BCM96368MBG6b
BCM96368MBG6302
BCM96368MNG   
BCM96368MVNgr
BCM96368MVNgrP2
BCM96368MVWG
BCM96368MVWGB
BCM96368MVWGJ
BCM96368NTR
BCM96368SV2
BCM96368VVW
BCM96368VVWB

Fromt he unit I have, from cpuinfo I get this out of it:

system type      : CHIP96368
processor      : 0
cpu model      : BCM6368 V3.1
BogoMIPS      : 398.95
wait instruction   : no
microsecond timers   : yes
tlb_entries      : 32
extra interrupt vector   : no
hardware watchpoint   : no
ASEs implemented   :
VCED exceptions      : not available
VCEI exceptions      : not available

Reason I ask is that somewhere around here I have a bunch of broadcom toolchains so I might be able to dig through he headers and see what's what If I know this, and can get the right toolchain in place, then I can use gdb (amongst other things) to decompile bits and bobs of the current firmware components

Anyone with c, gdb, toolchains & architecture interested in playing along? It's just annoyed me that this particular device has remained somewhat "illusive" for years now and its high time it gets looked at

Anyway, let me know.. This would be an interesting project ontop of a few other interesting ones I've got on the go

Cheers,

A

*edit* Just to add, once I get back from he shops in 30 mins, I'll use arm-gnu-eabi (generically) to see if I can get anything of interest.

Phew.. I've just seen that OpenWRT have already included this arch in their own toolchain Saves me some slavery I'll get the lot downloaded now and see what I can find If anything I'm interested to see what the BTAgent does and moreso what the BTAgent socket is for :-/

I assume you have read through Asbokid's blog on the HG612? Earlier this year I took apart his 64-bit toolkit and transmogrified it into a 32-bit equivalent for a fellow Kitizen. I have put both architectures of the toolkit here, available for public downloading.

Yeah I've read through quite a few of them scattered around the web Is he/she still an active member here?

Currently inactive whilst on extensive travels. I am hoping to hear from the maestro in the next month.

Indeedy. A quick "look-in".    But I haven't received any message in nearly a year!

That's an ARM toolchain.

If you go to Asbokid's blog and look at the panel on the right hand side under Official Resources, you'll find links to the GPL sources which contain the toolchain you need (MIPS).

Alternatively there's buildroot which is the same toolchain used for the HG612.  Or, if you're really, REALLY desperate... OpenWart 

But I wouldn't advise the latter. It's been rather extensively modified.

arm? I got mips here? Ok now I"confused!! will contact AsboKid....

That might explain why I can't get generic decompiles from the  lot...

Cheers,

Ade

arm? I got mips here?

Yes Indeed.

If you go to the following post you'll find a link to my repository which now contains the GPL sourcecodes as well. These include the toolchain you need.
