I'm trying to control an AD9956 EVB using the ADI s/w from my Windows 10 laptop, and I couldn't get any response out of the board. Here are what I found so far:
-- When first connected, the board showed up in device manager as unknown device
-- I followed the instructions in the AD9958 AD9959 EVB-flash.txt file and the DriverGuide.mht files to reflash the on board EEPROM
-- Now board shows up as ADI development board, and 16 Bytes were read back "successfully" : C0 56 04 26 EE 01 00 00, followed by a bunch of FFs
-- After connecting a USB cable to the board, USB Status LED CR2 blinks
-- I fired up the evaluation s/w (Version 2.0, downloaded and installed 10/12/2020), and the splash screen says "Software is up and running ..."; I can't tell if the text is red or green! Supplied voltages on TB1 are at 1.8V and 3.3V as printed next to the pins, and 1.8V is supplied to CLK_VDD (also shows up on AVDDx connectors).
-- Bottom left corner of the s/w window says USB status: Not connected; DUT Type: NONE
-- It seems that the s/w is not talking to the board. Is there a different driver or s/w that I need to use with Windows 10 (home edition)?
-- I put a scope probe on the RESET_U, SCLK_U and CSB_U pins on connector U13 and click Master Reset, Load and Read buttons multiple times, CSB_U stays HIGH (3.3V) . No signs of life from the other pins.
Would you please advise how I should further debug the problem. Thanks!
Just a couple of things to check:
1. What is the current consumption on the 1.8V and 3.3V power supply?
2. What are the jumper settings of the evaluation board?
Thanks, Mark for the suggestions. Seem I have inadvertently killed the 9959 - after I replaced the EVB, USB started talking, and I was able to get outputs using the supplied example files.
