How to JTAG a DM500

[Devilfish]

There's now a guide, pictures and all the tools you need to JTAG your DM500.

You will need these tools if your clone has been zapped by the Gemini 4.3.1 image.

Untested by myself, don't use Gemini lol.

Njoy!

hi

all works fins but when i click on write the program quits and nothing happens ? any idea why is it doing that ?

[yahoo.com.pl]

The connections are:

LPT————–> Dreambox/Clone

2 –> 100 ohms –> 11 ( Halt)

3 –> 100 ohms –> 9 ( Tms )

4 –> 100 ohms –> 7 ( Tck )

5 –> 100 ohms –> 3 ( Tdi )

11 –> 100 ohms –> 1 ( Tdo )

25 —————— 16 ( Ground)

Th pins 18, 19, 20, 21, 22, 23, 24 e 25 of the port LPT must be shunted between themselves, like commercial jtags has.

[Alpha4321]

all the connections are correct usinf 100 ohm program connects fine and indentify cpu and flash ,but still when i click on write ,the program quits and nothing is written to the dm500 .what could be the problem ?

[Bigmemo]

[cozierj]

Hi all,

Does this jtag work ?
It seems a though no one has been able to get it working successfully !!

What is the scoop on it ?

Regards
jr

[Devilfish]

unfortunately it's a grey area. no-one is going to brick their box on purpose just so they can try and JTAG it.

If you have a dead box then you are simply going to have to persevere and hopefully you'll be a mentor to others.

[bro]

waiting for a jtag lead from tailor made circuits then i will try it myself,hopefully will be here tomorrow
in the meantime i ordered a 600pvr lol

[Jojo2003]

I tryed all kinds of jtag..No luck at all...

[Jojo2003]

i have the jtag-interface but i cant boot my dm500

Jtag uses When DM500 not booting...when is booting you do not need for jtag...Maybe you mean you can?t connect with your dm500 with jtag...

Omar,

I tried your method, hooked up the jumper then switched to the next set and it still didn't connect, guess it's a dead dm 500.

Although when I do hit connect with it hooked up to a jtag it does make the red light come on.

It just can't be dead... time to get more determined, lol

[Greystoke]

When I Jtag with the philips bootloader, I get no lights after the Jtag is done.

[revolte]

i have find other soft to get my dm to work
the interface is the same
LPT?????> Dreambox/Clone

2 ?> 100 ohms ?> 11 ( Halt)

3 ?> 100 ohms ?> 9 ( Tms )

4 ?> 100 ohms ?> 7 ( Tck )

5 ?> 100 ohms ?> 3 ( Tdi )

11 ?> 100 ohms ?> 1 ( Tdo )

25 ?????? 16 ( Ground)

Th pins 18, 19, 20, 21, 22, 23, 24 e 25 of the port LPT must be shunted between themselves.
the software is attached
first you connect the cable betwen dm and lpt port then power up the dm
then open a dos windows and execute the soft and enjoy
tested by me and work 100%
the soft name is jtagdm500 so you unzip the folder in c and open dos windows
c:\cd jtagdm500
c:\jtagdm500>jtagdm500 -m dm500 -i
you have some thing like this

Hello all,

I have loaded the bootloader without a hitch and am having trouble identifying the tuner. Could anyone please identify this tuner?
http://www.pe2bz.nl/hamradio/uploads/images/DB500S/P1020064.JPG

[Donnie Darko]

Was the tuner like that when you removed the lid?they normallly have a metal cover on.
On top of the metal cover is a sticker,original dreams had alps/phillips tuners.Clones had phillips tuner stickers but who knows what make the tuner is?

[fireman1374]

Thanks for the reply.

Actually, that is not my receiver, I was searching and searching for an answer and stumbled across that picture which is an exact representation of my tuner. That is exactly how it looks as I removed the cover. And, now I see that I'm not the only one with one. I bought my Dreambox beleiving whole heartedly that it was genuine, but alas, you see the results.

[Donnie Darko]

Do you need to identify the tuner to jtag?dunno if thats your intention?I've got an original and clone,both are stickered with Philips tuner,and the cover extends the length of the tuner.
As for clones they work ok,just dont agree with people selling them as originals at original prices.
Also worthy of note the 500 production stopped well over 12mths ago.

[revolte]

hi
if you connect your dm to jtag and use jtagdm500 you see if the tuner is alps or philps like this

Hello,

as many of you I had my bootloader erased. I failed to get it reflashed using the windows SW :thumpdown:.

I just found this forum and this DOS tool :nurse:
Hope it will make it better... thanks for sharing it anyway! :rock:

[taretempion]

Hello again,

this is progressing very well: I got it back alive, but still need to fix the MAC address problem.
I managed to flash it with the Windows utility, following tips listed here: Dreambox Guides, Tips & Hints (http://www.dreamboxtips.com/)
It really described how to do it, and in my case worked at the first try!

I had found some mac address generator tool, that would generate some image with correct mac address burnt inside, but the generated images don't boot on my boot. So I'm gonna give it a try to the other DOS tool, once I have downloaded it.

[max_gee]

do u have a satellite or cable dm500,

what tuner do you have? did you try generating a mac using both tuner types? and it still didnt boot up?

[taretempion]

In the meantime, I also found this post on another forum: http://www.cardsharing.biz/forum/showthread.php?t=15870

Yes, some DreamBox 500S from Chinese are using the same MAC address in spite of the problem appear after 
I did not try this procedure personally; hope it will help you?
- You need to download using "Blue panel" the plug-in of "qSUB" and install it, after the MAC update you can remove it.
- Using DCC or similar software you need to browse to /var/etc and you will find file name "init", than you need to edit the two line bellow with your new MAC you wish to change.
"ifconfig eth0 down hw ether 00:12:25:2f:78:89
ifconfig eth0 up "

Has anyone ever tried/known this? With success?

[taretempion]

do u have a satellite or cable dm500,

I have a DM500s (sat) and most probably an ALPS tuner, as the running image with MAC address 00:00:00:00:00:00 is done for ALPS tuner. I didn't try other tuner models.

[taretempion]

I believe I have an issue with the DOS utility.
I tried following the recommendations to change the MAC address, but when I run the following command:

Couldn't make it with the DOS utility, so tried the init file in the /var/etc directory and it worked smoothly.

assuming you have a simple jtag cable (5 resistor one) you just need to place the jtag cable on the right spots on the dm500 board.

i try it but it does not work
may be the connection ?

does any image flash over now? maybe flash gemini back on to corrupt bootloader again pmsl

cheers

I got the same prob but imnot sure if mine is a clone or not.... The philips tuner is not a sticker, its an official imprint on the metal surface of the tuner. But on the back of he box it has the moditied spelling mistake
I think its an old 500c clone

Have anyone tried flash original dm500 with jtag?
It's the same procedure ,like cloned 500s?
Before few weeks I repair 2 clone's with my jtag .
Now can't connect to original DM500s.
Can any1 tell me for sure ,if is possible to repair boot loader in origin exactly like in cloned Dream?

what should i do?

[jrbaz2004a]

no i really have a problem that the pointer stop at 0% and nothing happens

Hi again

Maybe
1) try other blimg file./sometimes may be corrupt or fail version of blimg /
2) try cut little jtag cables /I have +- 8 cm on my jtag with +- 10 cm i has problem with connection with clone's /
3) change resistors /one one/
4) make bridge between 11 - 13 connectors in your jtag
with clones my jtag work
with original box this jtag can't connect

Regards
JRBAZ2004A

[ashraf_f]

thank you so much

it was because of the length of the cable

dear friends, my dm500s just went blank 2 days ago, when i powered it up nothing shows on the tv screen, no response from remote,
only the green power LED on dm500s front panel is ON now.
( i was using the older version of gemini, not the virus version)

so i thought a simple dreamup re-flash via serial would solve it, i was wrong!!!
dreamup does not load anything, it just shows waiting for acknowledge..
and hangs there forever.

i even tried hyperterminal and this is all i got.

http://images.filecloud.com/730844/none-jumper-console.JPG


so i tried omars method by removing the front panel cable and shorted the pins using a pin jumper ...

http://images.filecloud.com/730841/dm500-jump.JPG

and after i shorted the pins i was able to get this on hyperterminal

http://images.filecloud.com/730843/jumper-console.JPG


and i managed to successfully flash working image using dreamup,

now here is the problem, after successfully flashing the image
i removed the jumper pin and slotted back the front panel cable into it
and hooked to my tv, but nothing shows on tv.

so what i did, i again removed the front panel cable and slotted the jumper pin
back and hooked dm500 to my tv, and only then it worked and gemini project screen appeared on my tv screen, and i managed to see all my satellite signals were detected (but my ethernet port does not work!!) i have lights on my dm500s ethernet port and also the lights were on my 4 port switch. but the ethernet port does not detect dhcp ip and does not reply to
manual input ip!!

it looks like my dm500s will not boot or show anything on tv screen without me leaving the jumper pin there permanently!

please do i have to jtag it now??
appreciate all your advices here in this fantastic forum..

cheers and have a nice day.

[Vilsa]

Hi,

I have a problem. I have two Dreamboxes here (DM500). Unfortunatly they are fake and now I would like to rewrite the bootloader. With the DOSTool I was able to fix the sat-box but the cable box i wasnt able to program with the DOS Tool because I cant choose a cable boot loader from the drop down menue.
Is there any opportunity to chose another bin file that the DOS Tool will write in it or is there any other DOS tool that is able choose extern bins to write into that flash? Unfortunatly the windows tool is not working here because i have the chip JS28F640 in the box.
and as it seems you cannot programm that with the tool or is there maybe a crack existing for that?

I have a CRS2 programmer here, that are able to write into the bootloader. I also have an Adapter unfortunatly I dont get a connection with that either maybe i would be able to write into the flash with that?

[victorlcs]

anyone tried gemini 4.40 ?

Hi, I've jtag the dm500c, but cant connect with dreamup, it's just waiting for acknowledgement and nothing happens.

Hi gregobd

In the folder where the JtagWindows tool is located, do you have a blimg file there?
I experienced with this tool, when you click more the 4 times on connect, the tool crashed as well. So, I managed it as follow, start the JtagWindows tool, tryied 4 times, if the write button, wasn't enabled, close it and start the tool again (no joke).

Hope that helps

Today i am going to try to JTAG my DM500 (clone) and i have read the whole thread and found out that shahjees is giving very good instructions on how to repair the box without the use of JTAG. Has anyone really tried this before? Is it really working? If so, is it true about the box not operating without the jumper??? And finally the BIG question...

How the hell is it possible for the box to boot-up and allow you to flash with a new image if there is NO booloader inside. Gemini (not exactly Gemini but the libraries of the CVS) is supposed to wipe the bootloader and as far as i know, the images do not contain any bootloaders.. So????

I think i will give it a try this evening and post a feedback in here... ;)

maybe some can give me a hint...

have rescued recently my DM500C with NXT tuner

I keep testing Gemini 4.4 with different MAC addresses 00:09:34... on my box, but everytime the clone bomb checker tells me "Potential risk clone bomb..." I did also use my neighbour MAC address, without luck :viking:

Does any1 has an idea how to work around this, if at all? I know, do not use Gemini, but at the moment I am dependet on it...

Hi Tango,

You need to try many time, while connecting the program and power up the box. It needs to have the perfect timing, just try it, do not loose hope. I have been trough the same...

Now I'm having a problem with an original DM500 with a philips tuner.
For some unknown reason the boot when OFF.
I flashed it with the bootloader for philips tuners but in the end I can get a connection with the dreamup in order to send it an image.
The only way to get a recognition by the dreamup is with a boot loader that gives me the infromation it is a DM56xx but after loading the image (which takes a lot of time) the dream powers up but I can get i clear image, just a lot of horizontal and vertical tiny lines in black and white.
I put an image of the tuner.
My question is:
-Which bootloader must I use to get it working again?
Thx

Trying to jtag a dm500 -S with a alps tuner(BSBE1-706A) back to life using jtag windows as the chip is a TE28F640 J3C120 and i have read i cant use the dos way it connects and seems to flash ok (see piccie) i then close jtag windows power off the box remove the connection from the pc but when i power the box back up i get no green lcd light..nothing i try dreamup with nullmodem cable but just sits there not connecting even if i power on or of the box.
Do you reckon it might be the wrong bootloader(blimg) i am using i tried the ones in the d/loads or is there something else i need to be doing.

[Fergal]

Managed to get a different bootloader(blimg) and it seems to have worked as i have green lcd light and i can now get dreamup to connect it:dancing2:

Hi Fergal

I thought I had jtagged my bootloader ok on a clone dm500c with the Dos software as it had a philips tuner option built into the software but although the image flashed on ok I was unable to find any scanning options at all, so I presevered with the Windows version for which I managed to find a 'c' version of 'blimp' all is working well now. Obviously the Dos version only carries the bootloader built in for the Sat Philips tuner.

hi. i have problem to flash boot to dm500s JS28F640 with philips tuner. this DM is new and i will chang MAC . i write MAC in bat file and start boot uploud and all is fine. problem is that after uploud tuner cant find satelites and have other problems. maybe this philips sw is for cable tuner ? i have flashed ALPH and all is fine . how to flash this philips tuner ?

[jbvid]

@fricker
Hi
If you have the option to do a Satellite scan you have the correct bootloader, but you mention you flashed Alps, this is wrong.
If your dm has philips tuner jtag command line like this.
"jtagdm500 -m dm500 -d philips" without quotes.

Hi
Very interesting post BTW, I just have one, well two really questions for a dm500c clone bootloader, after generating the file with the generator I presume you have to rename the file to 'blimp' then put it in the correct folder with jtag_windows.exe? Also does it matter about entering the correct Mac address into the generator or just use your 'something like' posted figures?
Regards jbvid

[sparktikus]

micromouse i have tried the mac generator (cable) for my dm500c but i cannot load it up via jtag windows ,, when i write it says "could not open flash.bin"
i take it all i should be doing is renaming the mac generated file to blimg and it should load??? is that correct???

Remove the jtag end from the pc lpt port (you dont have to remove the wires from the board) turn box off then on again does the green light come on then? if it does you should be able to use dreamup to flash it.

i have tried omars suggestions already still no joy
and the philips bootloader in post 48 i cannot get onto box as stated in previous posts
i rename the that file to blimg replace existing blimg file ,use jtag win and write !!! straight away box pops up saying "finished"
but on working scren it says "could not load flash.bin"

think this bootloaders really naffed

sorry for buttin on but while were on the subject of jtagging i recently bought one for my dm500c and am i right in saying this is correct for the colours ? ;-
WHITE = 1
YELLOW = 3
GREEN = 7
BLUE = 9
RED = 11
BLACK = 16
jusr so i know if i get any errors i at least know its soldered in correctly.
thanks all.

[bigzuk]

i think the colour of the cables depends on where you bought the jtag they are they right colours for my jtag and i got it from tailormadecircuits


also my dm500 was doing the same thing getting to a certain percentage then crashing but eventually it would be 100% complete but i still cant get dreamup to send new image

mine was from tailor made as well.i've tried 100's of times and 15% is the best i can do.is there another windows based prog i can use other than dreamflash v0.1 ?.as far as i can see ive got a NXP tuner in my DM500c box and this is the problem.
has anyone got specific boot files for this particular driver ?.DOS based or windows.
thanks,.

[sparktikus]

think were all in the same boat with these nxp tuners
i see im not alone in getting this bugger to communicate ..
i do have another dreambox 500c with nxp tuner thats working correctly ! does anyone know how i can get the information of the working one to fix the duff one!! helping my fellow strugglers along the way!

thanks

[loncell]

someone on another forum had this same prob and another member posted a blimg for a NXP tuner but i dont have privilages so i cant download them.it seems there are fixes for them out there.

<--loncell added 138 Minutes and 30 Seconds later...-->

well after endless trying i managed to bring my 500c with a "NXP tuner" back to life via JTAGing.
here's how i did it be it right or wrong it worked ;-

i used jtagwin5xxx and put the "boot500c" blimg file thats knocking around in the forum (search for it) into jtagwin5xxx folder.
i then downloaded "dm500mac_generator_v2".
i then made a file and selected "cabel tuner" on the left.
i used the MAC address written on the side of the cardboard dreambox box it came in.
i entered these numbers and made a file using dm500mac_generator_v2.

now right or wrong i then copied this MAC .bin i made into the "jtagwin5xxx" folder and renamed it blimg.
it wont copy over the "boot500c" file as this a "file" extension and the blimg you made is a ".bin" extension.

now you should have both blimg images in the jtagwin5xxx folder.someone will correct me and say i only need ..................... but like i keep saying it worked.
i then asked jtagwin5xxx to connect and a split second later power up your 500c with NXP tuner.i then selected write and it went the whole 100%.

i disconnected the printer port jtag from the pc (i didnt need to unsolder it from 500c box ) and flashed as normal with dreamup and low and behold the service searching magically reappeared and allowed me to scan for channels.

i hope this works for those in the same boat who cant see the tuner so hence cant scan.

Hi,

it's just a post to obtain access to JTAG-DM500 files download.
Thanks to uploaders and all active people on this forum.

I'm not a good writer, so :
"see you soon"
(maybe)

[pardus]

There's now a guide, pictures and all the tools you need to JTAG your DM500.

You will need these tools if your clone has been zapped by the Gemini 4.3.1 image.

Untested by myself, don't use Gemini lol.

Njoy!

3 bloody days,
thats how long ive been trying to jtag 2 boxes, just keep getting errors, no stranger to jtagging either, tested cable dont know how many times, its only 7cm in length tops tried both DOS and Windows programs. When i was connecting the jtag today on both boxes the green light lit up on an otherwise dead box in fact a few times both the red and green lights are on, this only happens when connected to parallel and power. When parallel (jtag) is taken off the light goes out?
Any ideas this must be something stupid

regards

[blue15]

hi
is there an altrenative jtag points cuz i lost 3 contact points

[markh29]

I think if you trace the track from the 3 lost points you should still be able to do it

hi all,
I used the jtagdm500 dos program in order to upload the bootloader on my dm500. I used a pentium2 350. The first time I did the operation, it blocked at 0% of uploading. I switched off the box, I checked the connection cable and then I retried the operation, but I always obtained a comunication failure.

Please, can someone help me?

Thank you

I followed the instructions on the guide and everything went fine.

I would like to know if the jtag files for the philips tuner DM500-S Model would work for the DM500-C with a philip cable tuner?

I would like to know if the jtag files for the philips tuner DM500-S Model would work for the DM500-C with a philip cable tuner?
Hi
No, the 'C' uses a 'blimg' (Boot Loader Image file) and the 'S' uses either the dm500_alps.bin or dm500_philips.bin. The loader programs are also different.
'C' uses jtag_windows.exe and 'S' uses JtagDM500.exe.
You may find some of these in the D/L section otherwise use the very popular search engine.

wen i try too flash my dm500, it stop after the flash erase
and i try with different computer
wath i can do

[PeterChou]

I've used the jtagWindow program to reflash the bootloader successfully.
However, while I was using the dreamup to flash the image, the log window showed an message like this:
COM: The hardware detected a break condition.
Then no progress at all.

Is there anything could be wrong?

Thanks a lot.

[PeterChou]

Forgot to mention one thing.
Don't use Gemini 4.5. The same time bomb inside.

[tank30]

Downloading the guide. Hope it works. DAMN Gemini team! :)

[tank30]

Well i folowed the guide, created my custom jtag thingy and now im running the ALPS script. It says its downloading but it took 12 hours to get to 60% and its still going..
Any ideas why this is happening? I mean it should take around 10-15 minutes right?

Also is there a commercial ready made jtag connector i could buy?

thanks

[tank30]

well did everything according to the guide, flashing took around 22 hours but it finished ok. When i connected the serial though and rebooted the box , i got nothing, no led on and the box would not boot.
Any ideas? Heeeeeeelp please.

Hi
Did you have DreamUp connected and running before you started the box.?
You still need to flash an image on it with DreamUp.
jbvid

[cgscott]

If you aint getting an led then the box is dead my man. Try jtag again.

Although this process should not take 22hours mate.

[sarikth]

Hello again! I was not able to recover my clone using jtag.
When I use the jtagdm500 (command prompt) the green light goes on, but the program stops after "erase: done".
I was not able to use the windows version (a lot of failed tries!)
My flash is Intel TE28f640.
The jtag length is 10cm.
So! can anyone suggest something?

[Kelly_DK]

Hi

I have used the windows program and after a few try I got connection to the box and was able to write a new boot to my DM500. When I used Dreamup to flash a new image to the box it says boxtype 56xx and not 500.
What to do now?
