After the software install on two different PC's, I'm able to detect the presence of the SDP-B and in turn the s/w detects whether the ADRF6755 is attached or not. Unfortunately, I am still unable to control the ADRF6755 at all. After scoping the SPI between the SDP-B and ADRF6755, I find no activity on any lines when attempts are made to send data to the eval board. Is there another step in the process I am missing? Thanks.
