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

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

Many thanks for your contribution.

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 [code] 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** · 20-04-2008

You need to upload the photos using advanced edit.

this is the program

and this is the working boot

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 · 20-04-2008

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>

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.

yes the file to use in all is the second all other to try is not work...
Need to copy this file in folder to use the jtag_windows and rename it as blimg

thanks

To check if your MAC address box login to your box using telnet and enter either:

1. ifconfig

or

2. cat /proc/bus/dreambox

I found the info below elsewhere but either it loses something in translation or seems to do it twice.. so perhaps choose one method only.

To change your MAC address:

Use an init file:

Create an init file with another MAC address in a text editor (ideally a UNIX compatible one) and enter this:

#!/bin/sh
ifconfig eth0 down
ifconfig eth0 hw ether 00:09:34:F4:xx:xx
ifconfig eth0 up

Save this file with the name init and ftp the file to /var/etc on the Dreambox. Reboot the Dreambox and re-check your MAC address. Do NOT delete the init file after you have changed your MAC address.

Change it using telnet:

Login again to your Dreambox in telnet mode and click Format option and type:

ifconfig eth0 down ; ifconfig eth0 hw ether 00:09:34:xx:xx:xx ; ifconfig eth0 up

(xx xx xx can be any HEX double digits) and click enter. To check your new MACaddress enter ifconfig

I haven't tested it as I don't have a fake box.

If your MAC starts with 00:12:25 then it's a fake.
If your MAC starts with 00:09:34 then it is a genuine box.

Great job, Philip !

Thanks for sharing.

***Sharkadder*** · 20-04-2008

did you get it working then nafan from what philip explained to do ?

Don't forget to "chmod 755 init" to allow the script to execute...

You shouldn't delete the init file. It's not a permanent change.
If you delete it and reboot, you come back to previous MAC Adress... stored in bootloader.

Another GREAT and PERMANENT solution is to generate a bootloader binary file with modified MAC Adress :
I've got an archive named "dm500mac_generator.zip" to do this.
I'm going to upload and give you the url in this thread...

Here it is : _http://www.sendspace.com/file/l34l6d

Unfortunatly not yet. I haven't got 100ohms resistors to build my JTAG. I have several other values, but no 100ohms ! ;(

Doesn't matter, I've got another DM500S with Nabilo... so I can wait a few days to get the resistors in my mailbox.

**mhku** · 20-04-2008

Cheers Nafan. I've trying to edit the post but my internet connection has been playing up.

Do we have a definitive solution from someone who has done this end-to-end yet?

If you speak about MAC Adress solution, I think the ultimate solution is here :
_http://www.sendspace.com/file/l34l6d

It's called dm500mac_generator.zip and changes the MAC Adress stored in bootloader binary file.
You just have to put the MAC Adress you want (Maybe something like 00:09:34:xx:xx:xx ?) in this software, then select the bootloader binary you want to modify, and that's it : a new bootloader file is generated.

JTAG it, and enjoy !

bouba280 · 20-04-2008

Thanks to all , my dream is ok

adamedoe · 20-04-2008

Why does any one make it clear? and put a full walkthrough with pictures & comments?

I'm starting to think this JTAG stuff is only myth!

**mhku** · 20-04-2008

If you speak about MAC Adress solution

No- fixing a dead clone. If it's dead how can you change the MAC address?

Can anyone say "I fixed my dead clone by doing x, y and z. These are the steps I took and these are links to the bootloaders. This is my cable."?

philip633 · 21-04-2008

Hi again...

the step is easy and simple...

1- get the files to i add in this topic no others

2- see if have the right conf in your parallel port
ECP+EPP printer port setup + never use interrupt

3- make the simple cable parallel and resistor
DB25 male printer connector
6 wieres + 5 resistors of 100 ohms
LPT jtag
02--100r--11
03--100r--09
04--100r--07
05--100r--03
11--100r--01
25--------16

4- connect your cable in dm500 board
see my picture in attachments

5- try to make to connect in dm500
in same time to power on in dm500 press the connect in jtag_windows
this is the problem....try it lot of times
if see the write on just press and in 2 mins the your box is back to life

this is all

sorry about my English.

Has one try with cas3 programer, it can be connected with JTAG cable.

philip633 · 21-04-2008

With the tests done I've understood better how it works great:

The secret is in 1º do connect to the program and then turn on the clone, but with a certain delay. This delay depends on the speed of your CPU, the faster CPU's, minor the time/delay (between 0 e 1 seconds).

Change the priority of the program jtag_windows.exe on the task manager for the real time which must turn more real the delay itself, once the program will give maximum priority of the use of the CPU.

About the timming, if it shows you only "ERROR:register test failded" then the jtag is ok, but you have turned on the box sooner then expected, if it shows you the 4 times "ERROR: communication with LPT/JTAG", then you must turn on the box sooner, or the jtag isn't ok.

Remmember that you must connect the box always after making connect on the program.

This i hope to give help......

**mhku** · 21-04-2008

Is the photo of the JTAG cable shown in post #1 not relevant?

Did you try connecting via the RS232 port (with a suitable connector) as this is connected to the part of the PPCB where you've soldered the cables to?

camoufle · 21-04-2008

please, this information not completed. Thank you

big thanks for you

my english is not perfect but my french is very good
