hi i tryed jtag drembox 7000 connecting with dream ok the min i press write program closes any ideas please

[sosidir]

thanks very much

Thank you very much

The connections are:

Picture 1 referance....


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)

Picture 2 referance.........

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


Now, The cience of the thing is doing the connect and turn on the box at the same time.



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

The secret is in 1? 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.



After you must warp/straight the pins on the adaptor switch of the box, so it fits faster on the electric switch.

By end, you must use an electric switch easy to fit, I have used one triple (from the bad ones), but I had to dismount it and press their electric pins to don't make bad contact.

When doing "write" the program sends immediately the boot, that is the file "blimg".

The file present in this attachment is the boot of a DM500 and tunner ALPS of CRC-32 9055B110, once again thanks Matrix10, because I've tested a boot that were supposed to be for the DM500 and ALPS and it didn't worked, and this one in the attachment is guaranteed it works.

after sending the boot of 128KB by Jtag, you can turn on the box with dreamup and by rs232 send an image

dm600 tagging

Hi guys

I have two dm600 here from china - one I put a gemini image in and it would not boot afterwards, I thought this should not be a problem as I can serial load it - but even that will not work

So do I need to jtag it to get it into a state where i can serial load it afterwards?

Is the above information relevant to the DM600 and do I need different software?

The other one i put nabilosat image in and that's working fine, is that the best image to use for chinese dm600?

Thanks in advance
dicky

I try with my clone.
Connected, and not working
Dont recognize the flash type ( Intel Unknown )
After erase flash, exit or wait long time 1-2 hours. Nothing happened.
