Version of UHD i am using is 3.10.0 (pre_rfnoc) I have been attempting to change the RF frequency from the FPGA using SPI communication to do some frequency *hopping jumps in steps of 100 MHz after the first tuning call I am making from host. *
What I am doing is: I create a custom "stream_live" signal that is based off of valids from radio/DDC block. After this signal's assertion, I attach the spi core control lines (the strobe, address and data) to the custom writing module I wrote. I am not seeing any success with this. I do know I have the correct values because i used Visual studio to compile and debug the values that were being written for the call from the host to line up with what I have as values stored in the FPGA (which btw, is another question since what ADSIMPLL or the other tool provided by Analog Devices doesn't match at all with the 5 registers(registers 5 through to 1) ). Is there something I am missing here? (for the curious, we need to jump frequencies to do averaging to mitigate some noisy artifacts in our image)?
