[vispoo]

thanks

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
C:\Jtagdm500>jtagdm500 -m dm500 -i

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. What should be the wattage of the 100ohms? They had 1w and 1/4w. Every one is writing 100 ohms but no one says what wattage. Thanks

Hi, I just joined the forum

I have difficulty with English and politely ask how I can get the downloads to revive my DM500S clone.
I have trouble with voltage to LPT1.
Thanks
