Dear Help,
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!
Benjamin
Hi Benjamin,
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?
Best regards,
Mark
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.
