Help on getting XBR onto cygnos v2?

[jimb0b]

I have XBR 3a on my Cygnos360 v2 (Falcon MB).  Here is how I did it:

• Dump original NAND with Cygnos360 v2 Toolbox 1.05 to orig.bin.
• nandpro orig.bin: -r16 rawkv.bin 1 1
• nandpro orig.bin: -r16 rawconfig.bin 3de 2
• Download XBR. (XBR_Falcon_8955_3a.bin for me)
• nandpro XBR_Falcon_8955_3a.bin: -w16 rawkv.bin 1 1
• nandpro XBR_Falcon_8955_3a.bin: -w16 rawconfig.bin 3de 2
• Flash XBR to second NAND.
• Boot up, got E79.
• Flash 1.01 firmware to Cygnos.
• Boot up, success!

Thats pretty much all i did apart from dumping the original nand (did via lpt ages ago) and i didnt change the cygnos firmware back. This was all on a xenon btw

Success here as well...

Don't know why I couldn't get this to work on the 360 nand...and I burned the same image too.

Anyway, I was running firmware 1.03beta and I had to revert to 1.01 to get past the E79.

Thanks for confirmation that it works!  It caused me to try one more time. :-)

works for me only if i put it on the secound nand. i think the chip fails booting from the first and than boots from the secound so imho you could easily think that it works on both.

just a theory.

Doesn't the 1.03 firmware require you to wire the JTAG part differently?

[jimb0b]

i did try to put the same image i flashed to the cygnos on to the 360 nand and it wouldnt boot and yeah firmware 1.03 requires different wiring

[jelle2503]

firmware 1.03 of cygnos should work with existing wiring

Can I flash xbr to xbox nand, then remove cygnos v2?

If so, I can use one cygnos v2 chip, on many xboxes with 256MB-512MB nands that are too slow to be read/flashed with parallel cables.

THANKS

No, I'm using 1.03 with the original wiring.  Works fine.

[NotMe]

dont know if it helps but i injected my keyvault and config into the xbr bin and flashed it straight to the cygnos nand and it works fine with no messing about, using firmware 1.3 and the updating wiring diagram from the cygnos website

What motherboard type? Edit: NVM, see in a later post you said you are using a Xenon.

I tried this with my falcon running Cygnos 1.03b2 and wired per new wiring without resistors using XBR_Falcon_8955_3a.bin and got a single Red light with E79 and secondary error code of 1033.

No, I'm using 1.03 with the original wiring.  Works fine.

Thanks guys. I'll try it out myself tomorrow.

You could, just install the jtag hack since the cygnos won't be there to do that.  I should note though, removing the cygnos quicksolder pads looks like it'd be a real pain, maybe use short leads?

What is the diffierence between flashing xbr to xbox nand via cygnos v2 vs
nandpro? does the nanapro lpt command is doing anything beside flashing the nand?

I have thought that installing jtag hack only needs the xbr image with my xbox keys to be flashed into my xbox nand using whatever method I want (cygnos/lpt/usb).

[neonpolaris]

You don't need a Cygnos360 at all anymore.  What the cygnos360 does is give you a second NAND to use, handles the JTAG hack, and allows you to read/write the NANDs MUCH faster.

XBReboot can run off of one NAND, but until a few days ago was somewhat unstable.  freeBOOT was stable, but needed two NANDs.  So people would use the Cygnos to get this.

Now XBReboot is stable.  So the only real advantage of the Cygnos is the speed.  I can dump my whole NAND in a minute or two, instead of longer over LPT.  (Any LPT users want to comment about how long it takes? An hour or so?)  Remember that it's good to get at least 3 identical dumps before assuming your read is good.

I bought my cygnos a couple days before XBReboot stabilized.  I don't regret it since I intend to tinker alot, and it will save me alot of time.

Oh, I almost forgot, having a Cygnos removes all the guesswork about if your parallel port is 'good enough', if your cable is too long, etc.  You can flash with a laptop with no parallel port at all.

Also, you seem to have edited my quote.  Odd.

@neonpolaris:
Thank You very much for the fast reply; maybe I was misunderstood, I already know what You have said in Your last reply (freeBOOT vs. XBR),

What I did not understand is "just install the jtag hack since the rawkv won't be there to do that", so here are my steps(based on your guide), please tell me
how and when I should install the jtag hack:

•Solder Cygnos360 v2
•Dump original NAND with Cygnos360 v2 Toolbox 1.05 to orig.bin.
•nandpro orig.bin: -r16 rawkv.bin 1 1
•nandpro orig.bin: -r16 rawconfig.bin 3de 2
•Download XBR. (XBR_Falcon_8955_3a.bin for me)
•nandpro XBR_Falcon_8955_3a.bin: -w16 rawkv.bin 1 1
•nandpro XBR_Falcon_8955_3a.bin: -w16 rawconfig.bin 3de 2
•Flash XBR to XBOX NAND.
•Boot up, (I Should get E79.)
•Flash 1.01 firmware to Cygnos.
•Unsolder cygnos and remove quicksolder pads looks
•Solder Cygnos360 v2 to another xbox....

I have one 16MB xbox, and six 256MB-512MB nand arcade Xbox's of my friends, So I can't use parallel. I need the speed, and I want XBR.

THANK You again for You time, Rami.

cygnos 2 don't work with big nand jasper... yet

and why would you wanna go through the hassle of soldering a cygnos v2 to a board everytime, just to dump/flash a nand 
then why not set up a stable LPT setup?

plus if you remove the cygnos you need an alternative JTAG wiring setup.

[neonpolaris]

just install the jtag hack since the cygnoswon't be there to do that

I find it irritating that I'm still being misquoted. Look at my original post.

Yes, you need to leave the JTAG hack in place for XeLL and the rebooters to work.  If you take the cygnos away, you need to put in the JTAG hack.

Jelle, he wants to do it for the speed.  Maybe he's faster at soldering than nandpro is at dumping.

Do remember that the cygnos doesn't work for 256/512 NAND yet.

Again, I must say, unsoldering the quicksolder points on the cygnos looks like it would be a pain. If you do plan on moving a cygnos from console to console, consider adding small leads to them and using those, or something.  Less chance of ripping something off the board when you can work one wire at a time.

[jelle2503]

if you want speed you'd better be looking at an usb alternative (olimex).. cygnos has way too much solder points for it to be useful as fast reader for one time read/flash

[Tiros]

I dont know why someone doesn't just do the pcb layout for the LPC2148 and be done with it.
It could be single sided, the sparkfun website has the schematic. I picture a square board, with all the arm pins simply brought out along the 4 edges. Its already 3.3 volt so none of the so called "level shifting" resistors etc are required.
In fact I think all you need is the crystal and 2 caps or so.

The 2148 is about $9, more than a pic, yes, but has "real" usb, tons of flash, ram, and other hardware for future stuff and imho in the end less trouble. Maybe add a few extra parts like the 232 level shifter/programmer also on spark fun, then you could flash the arm with it as well as monitor/use the 360 (3.3v) rs232 port.

Im not knocking the pic project, its allways nice to see some real homebrew
Lets see a little more

The Cygnos V2 1.02 firmware requires its own SMC code in the image so the JTAG hack works. This goes as well for the 1.03beta. The 1.03beta should be used with a new JTAG wiring, but can be used with the old wiring. OTOH it seems the old wiring doesn't always work with the 1.03beta.

So if you want to use XBR on the cygnos (no matter if on the original or the Cygnos NAND) you have to use firmware 1.01 or a JTAG wiring independent from the Cygnos'. Or, what I would prefer, the Cygnos toolbox patched SMC code inside the XBR image. I just don't know how to do that!

The internal/original NAND will work too, even with Cygnos installed. I tested it with original kernel/dash on internal and XBR on Cygnos, works both perfectly, and I also tested XBR on internal NAND, original kernel on Cygnos, works as well. Yes, I tested if it really was the original kernel running...

Still, I would like to know how to get the new Cygnos SMC code into the XBR image. Someone has to know how to do this! Please help!

I think what you want (i don't have a cygnos) is reply 3 here http://www.xboxhacker.org/index.php?topic=13540.0

@neonpolaris: Really sorry for misquoting You; It was very late here. Anyhow I did not knew that cygnos v2 is not working on 256MB, I will go for LPC2148, more wasted money & time

@Tiros: Pic based solution could be the base for mass product chip, for normal modders, not people like us.

Btw, Do we have the jtag hack assembly/machine code explained & documented? what about xbr?
