How to JTAG a DM500

[confal44]

Maybe the pin 1 (TDO) of the jtag connector in the dreambox is wired to the other side.

No , wire to the other side , but on the cpu

[trickykid]

excuse mu ignorance, but exactly is jtag? and what does it do to the dreambox?

[brams]

excuse mu ignorance, but exactly is jtag? and what does it do to the dreambox?

It's a special cable that allows a PC to try and recover a Dreambok with a nuked bootloader.

[MastaG]

Can someone provide me a blimg for 500c with NXP tuner?

[ivanfed]

I fixed my DM500s today. When I use Dos version, it was staying on Erase flash done. So I use Windows version.

1. Unplug the box

2. Keep pressing on Connect and plug and unplug your box until Write comes up.

Just don’t press connect after box was connected.

[widar]

I will go crazy, after a lot of attempts with the Windows version, I ones had it run under the Dos version, all the way
to 100% complete, but no light or contact, when I try to load a img with serial cable, so I start to try to flash it again
if it still was something wrong, as my dos skills is not that good. Do I have to unsolder the J-tag before it works, or is it
possible to keep it until I know that the box is OK. Did I use
wrong bootloader? I did not have any choises, the default
was used, I think. Any help, or advices is welcome, thanks

[mihailovgrad]

I have got a 500s and the jtag points (see piccie) 1 (TDO) and 7 (TCK) are gubbed
looks like the copper has been lifted of the spots so i cant solder the wires to these two points
is there anywhere else i can use to solder the 2 wires to thanks.
ok i will try too jtag on my dm 500 it work

please help me for jtag dm 500 S

[sssllblue]

thx dude that helps ..........

[Giona3]

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.

This is what i needed

[singang]

First of all great Forum!

Jtag worked for me using DM500c but only that. I am still unable to flash box afterall with dreamup using the right cable (nullmodem), Comm settings a.s.o. before Jtag my box was not recognised by the dreamup software now at least I get the Boxtype: Dm500 back but there it stucks and won't move on. Tried it on different PC's left it for over 1h nothing happened.

Tried also using different blimgs, receiver types a.s.o. I get the Boxtype Message in Dreamup with only one specific blimg (alps) so that somehow tells me it worked but still unable to flash from that point on with dreamup. Also tried different dreamup versions, other flash programms and even another Power supply. Any ideas?

[sfwam]

thankkkkkkkkks

[dipla]

the philips bootloader ... ok
how can i get this file

[maraveasp]

hi all,
I have a dm500 that i try to jtag with no success. I have all cables for jtag correct and i am using the jtagdm500.exe.
The problem is that it starts downloading bootloader and it hangs in some point (some times 1% then 20% etc.). It is an alps tuner as the info told so but i tried all (alps,philips) with no success. I tried with jtag_windows and it starts writing flash but in some point again it closes without notice and flashing is not complete. I managed to make it finish the flash 100% only when download starts i connect with dreamup and leave it connected till end. Now the box starts the green light always on but it is like dead (no dreamup connection, no gemini start, no nothing)!!!
What can i do? or better what am i doing wrong?
Thanks in advance!!

[maraveasp]

Hi again,
Finally i found the solution after making a better search on forum. It is a must to connect pin 25 of the lpt that is gnd, to the dm500 metal case and pin 16, so the gnd of the flashing computer is the same with the gnd of the dm500 because as i believe now the reason that was stack in download was because of errors on transfer. It may be better to use a shielded cable and connect the shield to the gnd metal case of the lpt plug and on pin 16 on dm500.
Thanks to every one in this forum because without their problems and solution i don't think i would have been able to do it.:adore:

[Ma24]

Yes I have try the JTag on my DM500c and with a different blimg file I am up and running. It was dead no light no telnet to box no dream up, no answer from box DEAD now its alive and kicking!:cheer:

[quarkmaster]

I have read all post in this thread and still had problems with JTAG.

But then i tighten the LPT plug to the PC with the screws and then it worked with the dos version.

[BigCeti]

good thanks ;)

[seraph77]

Hello,

[mebken]

My dream had a good MAC address But THE GEMINI 4.70 detect it as clone. So, I will try the JTAG. Thanks for the tutorial.

[edzez]

Hi
Are you using a Null modem Cable with Dreamup software to put a new image onto the dm500 ????, (Untick use network) this is the only way after Jtagging in a new bootloader.
You cannot use FTP to load image.
If still struggling you could have a hardware problem if no lights on box.
UPDATE : Try this lot (Attached) for DM500 Cable, it worked on mine

Hi all need to jtag my dm500c box which software would you recommend ive got software for the 500 but not sure if its for the c t or s version or if that even matters the other thing i noticed was on a pic i seen of a jtag loads of pins have been joined together need to know which ones thanks please help

[tonymontana079]

hi everyone just tried to jtag my dm500c and went completely wrong lol melted the contact points off the mainboard. does anyone know where i can order a decent replacement mainboard (closest to original) ive found this one but not sure if its any good http://www.dreambox800.org.uk/Mother-Board-For-DM500C.html#
can someone please let me know if they know anythink thanks:wink:

just ordered a replacement board from this site but having trouble with them so be careful when ordering i will update if i receive the board or if its a site to avoid.

UPDATE: received the board now fitted it and all working well so far has been working 3 days so far so i think its safe to say replacement boards can be ordered from here. please note i did receive a different board to what was advertised on the site but still works so still happy. last resort for anyone having trouble with using jtag on their box.

[boxdm]

where can I find tjag dm 500 software

[zooss22]

i tried to jtag my dm500 but the progress bar was on zero for 10min i unpluged the power now the box doesn't power any suggestions

[vispoo]

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

Hi mates, I have done it before, last time my jtag was successful but this time it did not work at all, unable to connect. I had to make the new wire the old one I gave to a friend.

Hi.

I have a DM500S clone.
I tried to jtag it with the dos program, but it says Flash info: INTEL Unknown, and stops at Erase Flash....done

I have tried it with the windows version, the connection is ok,

In the End it says Finished Ok.
I close the program, shut down the dm500 power supply.
Connect it with my television, power on the dm500, and nothing happens. Dreamup can't see it also.
Can you help me what am i doing wrong?

I have created a bin file with the mac generator, renamed it to blimg, and overwrite it with the original in my directory.
The tuner is alps.

Hello Dear,

Good Day!

I have been trying to get my Dreambox back in order but I was told that it was due to the image I flashed it with that caused the problem.

Please what do I do now?

I have tried the windows jtag program, switching the box on just after Connect in the program, also with various slight delays, but just keep getting errors.

I have notice youtube videos which all seem to use the Jtag DM5090 vniekjd2 and these seem to do the job quickly without any problems. Is this just a case of good video editing or is it a better method of resurrecting a DM500.

Any advice will be a great help.

thanks,
doki


FOR DM500S, if your intel flash is JS28F640, use the dos program. Only for DM500S, sat tuner because the bootloader is for sat tuner. For TE28F640 flash chip, you can only use the jtag window program, load the right bootloader for your tuner, ALPS and Philips is different. Change the 000000000 to something like 00:09:34:??:??:??.

For DM500C, CABLE bootloader is diff from SAT. only 1 file for the tuners.

Trying to Jtag my DM500S with jtagdm500.exe but after flash erase nothing is displaying in the screen (no upload etc.) Any ideas???

After JTAG you must upload an image with DreamUp ...
With JTAG you did just upload the bootloader ... I think ...
.. fighting with some similar problems ...

[mikulas7]

So ... here is my story :

First of all I JTAG-ed it correctly and flashed up with windows progy ... but nothing happend .. so I flashed it a few more times ...

Then I found the DOS progy ... but did not know is it Alps or Philips I have ...
So I flashed with both a few times .... ( I think I have Alps .. after I read a few hundred site's about it .... )

It's flashed now in DOS/Alps ... but still cant reach it with RS-232 DreamUp ...

Any ideas ?

[SHANIS]

Yes you need to JTAG it ...
You have detailed instructions at h**p://www.digital-kaos.co.uk/forums/f34/how-jtag-dm500-1954/index8.html

Thanks for the reply bro

Even if i use Jtag, I don't think i will beable to upload the image through Dreamup ? bcz my serial cable connection doesn't work on this box...I use to upload image through FTP.

Is there any way to falsh the image through Jtag?

[henriqueramone]

I went to upgrade mine, time to restart, do not start anymore. By connecting the DM500S at source, the Green LED is lit directly. I tried with the serial cable, but does not connect dreamup. Anyone know how can I solve this?

[mtv1]

try an older version of dreamup the one on my siggy works on the 500s keep trying ;) and good luck :)

any reason why the dm500 jtag files dont seem to open and connect via the connected jtag

[yoboydb]

Hi. I am trying to jtag using DOS but cannot connect. I guess my CPU is version2 which I have to solder the wire to the CPU port.
Where can I download the windows version?

Ok now I can use DOS version with version2 CPU now.

Just a bit wrong wiring at the tck and tdi at first.

Thanks you guys for the information. Be sure to solder 16-25 of the LPT.

[onepic]

Hi all,

I have a death board with INTEL TE28F640 flash and i was intend to use windows version of JTAG as some ppl. are write above. The JTAG is a simple one with 5 100ohm resistors and is OK because if i use the DOS verssion the board is recognized but unknown INTEL flash message appear. So the problem is when i start the windows program with the right blimg inside it connect to the board and memory but when i click write the program it close by itself. Is this because the CPU (i have a Intel 2GHz Pentium Dual Core E2180). What i can do ? Thank you !

[scubidoo]

i try to use windows but alway windowsjtag crash

dont know what to do

help please

[chrisvaldez]

Just bought myself a soldering iron....here goes! Thanks for the guide!

[une]

have someone testit and dm itis a live pm me thanx
how it functions?

[TDCroPower]

The dos programm reports flash intel unknown and stops after 'erase flash done'.
The windows program gives an 'could not determine parallel interface on your pc!' and stops.

All this on vista. If I try XP will it make any difference?

i have the same problem, any solutions for this?

Hi all,

I have read the thread and successfully created a JTAG cable as outlined in the tutorial. When running file 1info.bat all i get is
Register Test Failed. Check Cable connection.
Target Test Failed. If you need help, run "flash help"

Please assist as my DM needs to be JTAG as i have no visible lights when power is plugged in.

can anyone pls tell me how are the wires connected to null modem for dreambox 500s ?
i bought a null modem.. but i get no connection with dreamup...and i tryed EVERYTHING
pls help

[Jane11]

Does anyone know if there is a source code for the DM500 JTAGing? I mean the source code that recovers DM500 that has a faulty bootloader.I found only compiled version.
Thanks

[febo1234]

can I use windows 7 for flasing 28f640 ?

[coreykippins]

i tried jtag my dreambox dm500-c but it is still shutting down and not comunicating with pc

[abs351]

i have gone throught the whole post here... i have a dm518s which is like the dm500s i have the TE28F640 flash chip, im assuming i need the windows version of the jtag tool. overall i have done this and still no comms with dream up... i know dream up and null modem cable works as i have flashed another box at the same time. any thoughts?

[tiranova007]

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!

Hello, please, JTAG for DM500S and INETBOX300S is different?
Thanks!

[ameer4321]

hi , nice work

[ahacomp]

There is the answer for you, from other forum!:
"The clone maker would have routed the other pins out because of R600-R603 pullups but as output pin 20 needs no pullup they probably left it unrouted. In which case you'll be SOL. Even with precise drilling it's near impossible to get at unrouted BGA balls without wrecking the board, because of the power planes.

Dream JTAG won't work without a connection to processor pin 20. I'd say you're stuck with a brick. The only way to save it is probably to desolder and replace the flash memory with a newly programmed chip, which of course requires SMD rework equipment not to mention a fair bit of time. Not economic. Those clones weren't meant to be recovered."
Good luck!

Thanks.... I will try another method

I doubt, the speed may not b there. How about try using a usbjtag, it proven to be ok. I hv tested them. The latest is usbjtagnt. FW provided by their forum. Caution, some Anti-virus detect their FW as trojan, to use them, u may hv to disable the Anti-virus SW for that period of time. Try google usbjtag u may find their site and a u-tube tut was provided too.

What about this? Seems simple enough. May be a bit too slow with USB->Serial but it is wort a shot.

[jatrophaseed]

I doubt. No harm trying.
My present solution to BL and corrupted flash is: replace the flash. I hv all the tools. UP-2008, hot-blower, clips and liquid flux etc. <5min blow job... hehehe....

What did my link disappear?

hxxp://marsohod.org/index.php/ourblog/11-blog/163-marsblaster
google translate is needed.

Well all important inputs are covered. (tdi,tck,tms,tdo)

Don't know if it can connect to DB? Maybe it needs a special connection handshake or something. I have no idea.

Edit: The MarsBlaster only takes "max2 cpld" .SVF files, which means it doesnt work? Or can i convert a DB .bin to .svf somehow? It's just binary data isnt it?

May work but hv never find our the corresponding connections of miso, mosi, rst clk with trst, tck, tms, tdi tdo , halt. Some expert did able to flash without hving to connect trst, I was never sucessful with that.
My made-do atmega progger, "usbjtagnt" is able to flash bl, but parallel port progger encounter problems in connectivity.
Pls share your experience with us if u get yr Atmega progger whether parallel port or USBport to flash BL.

Master DBT, you may just start another question session with many noobies dont hv comport or parallel port!!! hahaha...... Also after jtag still hv to load image to box.

Another solution is just change the Flash28F640. (Preferred Intel js28F640j3d75 which is more stable).

[DBTraitor]

ya true... :)

Actually youtube got lots of tutorials... I am quite surprise to find many videos on dreambox. Makes my life easier because I dont like to read ......

[tomori]

hi !!! does jtag works or it does not worth it ????

[jatrophaseed]

Jtag will load the BootLoader if your box is bricked. But if you hv a flash progger and hv saved a dump of the chip, then it not worth the hassle fiddleing the pin location.
However, jtag you dont hv to do any soldering or hot-blower to the box.

[ultrakiasu]

.

Unfortunately, unlike earlier batch of dreamboxes, in most recent years' batches, the JTAG DIP pins are not soldered on board, some crude soldering are still required.

[jatrophaseed]

No need soldering, if hv lead pins, just use socket from 10 to 20pins. If without leads, just put in 0.8mm pogo-pins for various STBs configurations. This way save lots of tome for many models and CPU configurations.
This is good for many same model which need jtag upgrading. Push & load, push & load........
If soldering, die liao......

[jiangou2007]

i try to Jtag my DM500C by jtag_windows version but keep getting
"could not determine parallel interfaces on your PC !"

anyone could advise or guide me?thanks.

[jatrophaseed]

Windows version in the jkey.def you must hv the JS28F640 and also the CPU IBM chipset defination loaded. I too never suceed in the windows version or by chance I may be able to load the BL in a blue moon. I since gave up that and used the USBjtagNT. It cud be the 232 chip not compatible or my entry of the definition is wrong.
Also a some of a givio-port sys file needed which always make my other //port program like PonyProg goes bad. In Atmega progging, my fuses always load wrongly with that givio sys file.

[fitoguitar]

Hi
Are you using a Null modem Cable with Dreamup software to put a new image onto the dm500 ????, (Untick use network) this is the only way after Jtagging in a new bootloader.
You cannot use FTP to load image.
If still struggling you could have a hardware problem if no lights on box.
UPDATE : Try this lot (Attached) for DM500 Cable, it worked on mine

just use a null modem cable and dreamup to flash new image. Your image is corrupt. Does not require JTAG.

I all,


I've got one DM500S briked, and I need to wake with JTAG cable.

Yesterday I had one accident with my Solder Iron, The 5th connector (according with the schema above), came glued in my Iron. I wander if there is any redundant connector in DM500S board. I wander if any one have the DM500SV8 Electronic Schema to know where this connector will go (to create one alternative).
