Hi Albert

I used the same cypress board and i bought it april this year and the only diffrence was i had the jumper closed but after reading vu.pdf i opened the jumper but still no connection i have tried with connection 1 3.3 volt disconnected but with no luck .
On pin 1 2 3 is 3.3 volt when duo is disconnected from cypress so there is life in the duo. The only thing i can think of is a driver issue i have had a lot of problems with the broadcom test adapter(unitialize)

Hi aevegroen

Thanks for your explanation of the jtag i'm trying to do it for months to get a connection between my duo and xp, win7 and with different pc's but no success do you have the golden tip for me?

Hi Mick

Can you explain in detail what are the connections from vu plus duo 2 generic FX2LP USB2.0 chip tnx in advance.

The answer no!

hello do you see the on or boot light on the box.
when you don't anything than perhaps it is the same problem in the psu
NO JTAG at this moment.

I see that my posts have disappeared but i am still interested in how to jtag an openbox
S9 i have solved my problem it was a defective ld7550bbn in the psu.
