Dreambox 500 - JTAG Information

Can you give us a more detailed description of how exactly you did this? Thanks.

freon · 19-04-2008

How more details do You want.
I explained step by step, and on the first post from Admin you have it all.

***Sharkadder*** · 19-04-2008

so that software does work? some dude was telling me earlier that software won't work on the 500-s......mind you he prob's just wired it incorrectly if you managed it.

Oh yes I did several boxes

rest of the wieres connect the resistors and use the schematics placed on the RDI.
When You hit the connect simultaniously place the power to dream.
That should do it!

I've tried this method several times without any luck, even on an original DM500!

You are using the dm7000 dreamflash software correct?
Can you please provide us more details or some screenshots ?

hi,
I followed your method and exact pinning as written in first post by admin.
I tried many times but i get this message from the software:

***CPU and JTAG communications check***
ERROR: communication with LPT/JTAG
ERROR: register test failed
Check your JTAG/LPT1 connection and/or adjust your voltage regulator

Have you any idea what is happening? I became sick checking and checking all day, but nothing's wrong.

- Can I use the cable that is already built in dreambox which had 9 pin.
- How can I do bootable for dreambox.

Thanks

this is the same outcome on my computer on the above method....

now should i desolder the flash chip and look for programmer......

**Robbo** · 19-04-2008

Have you guys made sure that the PC is setup with the correct configuration of the parallel port?

I believe this would be in the bios setup for the PC.

As it looks like the communication has to be bi-directional.

and you are lacking a good communication to the jtag interface.

bajm6277 · 19-04-2008

I'm sorry if i seem sceptical but the fact that no one else got it to work just makes it a bit fishy. Until some other people start getting it to work I'm gonna say it's still locked. Anyone know any other good box's? I have a technomate I paid about €100 for which does unlock all the stations but it doesn't really tell u whats on. Maybe I'll get another dreambox clone? hehehe

falcorn · 19-04-2008

@freon
can you tell me if jtag that you use to repair dm500s is this _http://www.diygadget.com/store/building-simple-jtag-cable/info_12.html

sam_asta · 19-04-2008

hi
@freon

i tried your methode but .. nothing work can you plz explane
how you made it ?
thx sam

Hello,

My "clone" DM500 is also dead. But I have a programmer and the tools to remove the flash ic. I used a working orginel DM500 and removed the flash ic. I was trying to read the flash ic but I got the error:"manifacturer / device ID check error". In the program i could switch a option off, so that I wouldn't get this error. So now i could read the flash. And stored it as a bin file. But when a looked at the data in the bin file, all the adresses are filled with "FF". So my question: does somebody has a correct dump file of a working flash? Or is there somebody elso who also worked with a programmer a knows the error "manifacturer / device ID check error" Or does anybody know a different solution?

TuxBox · 19-04-2008

Good evening,

I do everything correctly but I have no connections with my 500.

Why?

Could made you tell me a bit more. Someone has managed to do so?

I am at the same level as the others, jump that I did that message.

ERROR: register test failed

***Sharkadder*** · 19-04-2008

I may be wrong but didn't the pdf file say to connect all coloured wires to the soldered blobs? (where your grey wire goes to on that picture). I have just opened the pdf and that is where all the wires are pointing to.

freon might be able to clear it up more when he comes online next

I have the exact same error

Any ideas??

Who claims to have repaired a clone with this solution says that tha cable shoudn't have more then 10cm

TuxBox · 19-04-2008

My cable is not more than 10 cm, and it does not work. Look at the photo above

rmontoya · 19-04-2008

I have the same problem and my cable is also less than 10cm

nafan · 20-04-2008

Ok, just have a look to this post _h**p://www.sat-universe.com/showthread.php?t=65017&page=4 (I don't know if other boards urls are allowed)

There are guys that were able to JTAG their cloned DM500S but haven't got a working bootloader bin...

**mhku** · 20-04-2008

Cable wiring is the same as post #1. Additional info:

2) Computer and BIOS configuration:

BIOS COMPUTER **** LPT Printer ****ECP+EPP

Windows XP **** Contr.panel-System-Hardware-Device>Porten****Printer port****i never use an interrupt!

3) Start program ****Connect (important) When You hit the connect simultaniously place the power to dream.
No Connection, Try Again (again) ****Connect then (important) When You hit the connect simultaniously place the power to dream.
If you have connect ****(important) Write right dm500...bin for a boot of 500 alps (what must be all the clones).
(boot file for DM500)

After you can use standard DreamUP to put new image

Hello

I try it in one adios dm500 and work

thanks

Hello,

Was it a cloned DM500S or an original one ?
Did you test your box after restoring bootloader : ie Network and tuner are OK ?

Can you tell us which binary file you used, and maybe give us an url to get it ?

Many thanks for your contribution.
