My 3000+ Venice gives the same values, exept for this:

edx eax
MSR C0010041 00002710 0000060A
MSR C0010042 12040606 040A0A0A
MSR C0010015 00000000 0A000000

MSR C0010041 00002710 0000060A is different to yours. It is a locked cpu.

AMD worker answered me that CPUs programmed by JTAG.
So, people, go to search engines and try to get some PDF/Info about using JTAG WITH A64 cpus.

Okay, people. You want guide to unlock your A64 ?
Listen here.

It is simple. :p:

1. take JTAG programmator. (most low-cost selfmade if 5$) :)
2. take PDF for JTAG implementation in A64 CPU (if you have any - send to me :fact: )
3. put cpu to programmator, poweron, flash register C0010042 and C0010041 with data from FX-57.
4. Enjoy your free-multi cpu. :slobber:

SO! IF YOU REALLY WANT THIS. FIND THIS F'ING PDF or manual or smth.else regardin JTAG and A64. And then I make a PCB and programmer for your A64s.
I give you a word that I make it freeware and freely distribute. BUT if you help me. Way 2: I'll do a lot of durty and timewasting work digging with protocols and etc. and of course I'll get success with this sometime, but. My time isn't free so it will be an expensive programmator then. So choose yourself. It is not a difference for me, I'll work on this way anyway, but.. i posted results words earlier. :stick:

I'm not sure what you are looking for, could it be something like this.

Here's tons of tech docs for K8s.

There's some too.

Largon.

That PDF isn't about JTAG.
On AMD Site there is nothing that can help us. I already searched there a few weeks ago.

We need something regarding JTAG intefrace in CPU. Not A64 even! Just AMD CPU. JTAG is already inside K7 cores. Maybe some absolete data from that cores are available. We need it

found info in an old amd model 4 PDF, gives pins and signal info, search Jtag or look on pages 37,63,77 (PDF pages), will dig deeper and see if anything else pops up out there, looks like you guys cought the big break.

orignal PDF to large heres the link
http://amd.com/us-en/assets/content_...docs/23792.pdf
and an attached .doc with the important pages.

Update, All pins are present on 939 processor except TRST# but there is a TRST_L rename? or are pins used for something new?

update2 on search of func data sheet 939 pin 31411, looks as if JTAG pin discriptions are posted there as well.

update 3: another Jdag related AMD doc "jtag1.pdf"

AM i searching for the right thing or just pulling up info that everyone already knows?

I could access the JTAG interface easily, I use it to repair broken PDA's.

However you need exact specifications on how to access the memory containing frequency settings etc. If you don't have these specifications it's impossible to even try and get it to work.

Congrats guys, seems you're very close to make this dream come true.

"jtag sum.doc" says something about connecting to the mobo debug connector, does this mean that the mobo already has the JTAG pins wired to the debug connector? I don't know if I'm making much sense but maybe we could use our own mobos to connect to the JTAG interface.

So.

Acrazar

You find correct info, keep going. All necessary pins exist on 939. TRST is available as RESET_L i think.

JTAG1.pdf - this is just short desc.

Openwince - it is just a software for JTAG-devices. We have it already. We need info about A64's JTAG.

Not sure, but we try.

Exacly.

So now you know what for I need some dead 939-mobo. To disassemble it and figure out how CPU NC_xx, STRAP_xx and JTAG pins are connected and where do they go.

PM me your addy I have a dead DFI Ultra D I'll send ya! Well I dont know if its dead but I tore off a couple of IC's when taking off the sealstring..

:toast:

I hope the release versions of the DFI NF4 have this debug connector so we won't need to make some nasty solderings on it :D

Without a doubt, they're going to make it, there are some truly smart guys working on this :D

No. We just Hardware Embedders :)
But you are right FX-55/57 for 140$ is extremely nice thing ;)
Even with a Single PC on it will be twice cheaper :)

the ultra-d has a debug connector

As for some research:

and good 'ol wikkipedia has some info ;-)

Oh yeah, we're getting some attention, and other relted topics here:

OK I am mailing off a mobo for testing.. It should be there in a few days I hope if it doesnt cost that much! If anyone wants TIN EOF to get it sooner you can send me money to help with shipping..

BTW, I forgot to say.

With JTAG programmator it is possible to do ANYTHING with CPU.
I think All registers will be R/W without any limitation. And you can unlock any CPU you want (even Opteron 8xx or other stuff) You can even lock FX back :) You can write a CPUID string like "4rory's Athlon 64 XSE" (X.S. Edition :lol: :)
So only the thing we need - JTAG algorhytm and technology for AMD Athlon cpu's.

I think that this tech isn't much change from K7 cores.
