Hi Quingnan, At the least, the microcontroller subsection is working. I'm suspecting that the DDS device wasn't functional during that stage or maybe it wasn't responding to any SPI requests coming...

Re: ADRF6518-EVALZ Board Software Issue
We have tried applying a 50mV square wave with a frequency of 1MHz to INP1 and INM1 while monitoring OPP1 and OPM1. We have not been able to observe any output from this though.

What software environment are you using? Linux or no-os?
View ArticleRe: VHDL sample code / wrappers for VC707 with AD9361 AD-FMCOMMS3-EBZ?
Verilog is what we use. Modern tools allow you to mix and match - so your blocks can be anything.
View ArticleRe: AD7291 does what on AD-FMCOMMS3-EBZ with AD9361?
The AD7291 is there to measure all the voltages on the board. That's is. We use it for our board tests, to make sure the power supply was stuffed correctly.
View ArticleRe: How do you get from Alert State to FDD
no-os. Software based off your source. I can effectively read and write every register on the AD9361 so code written in the form of ad9361_spi_write and read along with writef and readf etc is very...
