Dreambox 500 - JTAG Information

[Sharkadder]

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

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

I have the exact same error
ERROR: register test failed
Check your JTAG/LPT1 connection and/or adjust your voltage regulator
Any ideas??

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

 

[TuxBox]

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

 

[rmontoya]

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

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]

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,

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. :-righton

Hello,

Clone Dm500s....
2 different
one with yellow led in lan and one with green

Did you test your box after restoring bootloader : ie Network and tuner are OK ?

Yes i test and work fine...
all channels is scanned and the network is ok

Can you tell us which binary file you used, and maybe give us an url to get it ?
Many thanks for your contribution. :-righton

sorry
i read again the rules in forum and if is ok i add in my next post

You can add a URL to a file, just disable it by adding and underscore before the HTML like this _http://www.somesite.com or use the

 brackets.

If you have the bin file then upload it to somewhere like sendspace and link to it from here. :)

Hello,

I made the JTAG cable. But when the DM has to connect I get this message:
cpu seems to be ok (so this ok!!!)
memory check (But here it goes wrong!!!!)
Flash Memory ID's do not match! (should be 0x89 and 0x17)
Are you sure this is a Dreambox DM7000s?

(See attachment)
Is this a know problem? Does somebody knows what I'am doing wrong?

 

[rolfw]

You need to upload the photos using advanced edit.

 

[philip633]

nice one philip, some people have been saying jtag doesn't work. Your now the second person to confirm that it does on here, i noticed the boot loader you included is a different name, i don't suppose that will matter, but at least i can tell my mate it's the alp's tuner he needs to use and not the phillips one as he wasn't sure.

Hello Philip663,

I tried it with your program and bootloader but i still get this message:
(See Attachment)

I connect my JTAG like this:

LPT J61
02--100r--11
03--100r--09
04--100r--07
05--100r--03
11--100r--01
25--------16 (Short circuit LPT 25 t/m 18)

Did you used the same connecting? Or do you know the error message?
Any Tips?
Thanx in advance

 

[bajm6277]

I got it working through the jtag connection too. I changed the compatibilty mode of the jtag program to windows 2000 & it finally connected. Anyone know how to change the mac address now?

yes this i use and work

check if you have this in your PC>

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!

and need to make lot of try to connect...
in some board i try 2-3 times and some other 20-30times to connect.

Need to copy this file in folder to use the jtag_windows and rename it as blimg

thanks
