Im trying to use jtag for about 3 days with no results, I have a DM500s clone can you describe step by step how you made it???

thanks in advance

XP SP2 PC used
ECP+EPP printer port setup + never use interrupt
DB25 male printer connector
6 wieres + 5 resistors of 100 ohms
ON printer connector short connect pin 18 to 25 and connect the last wire.
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!

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

 

[freon]

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

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 ;)

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.:-worship

- 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......

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.

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

@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

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?

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
