I’m using an eval-AD9956 in a Windows 7 pro 32 bits box. I’m facing communication issues. Whenever I make changes on the evaluation software I load the data to the device, nevertheless if I try to read the data back, the dialog box goes back to the initial value. The I/O automatic update is enabled. The jumpers W2, W3 and W4 are set for PC control. When I start the evaluation software the initial window shows that the software is up and running. Also the ADI development tools are recognized in W7 control panel.
The USB status CR1 red led keeps blinking and the VBUS CR2 Led is always glowing green. What am I doing wrong? How can I fix this?
