New ContributorUnrecognized output fir II
Hi,
When you are using the FIR II IP with Lite edition there will be time limited SOF will generate.
Are you giving any reset to the FIR IP? If Yes, try changing the reset polarity on HW(eg. active low to active high).
Thank you

Frequent ContributorHi Daoud,
Do you mean you are using Lite edition? FIR II IP will work but it will need license to generate full bitstream, else it will be time-limited bitstream. If you are able to generate the SOF then it should work on HW.
How are you trying to see the output data? Are you trying to capture using STP?
Thank you

New ContributorHi,
Yes, I am using Quartus Prime Lite edition. I am utilizing the Nuand bladeRF with a Cyclone V FPGA. You can find instructions on how to build the project and deploy it on the board in this GitHub repository: https://github.com/Nuand/bladeRF/wiki/FPGA-Development. I am executing specific Linux commands to build the project, which generates an ".rbf" file containing the bitstream. Afterwards, I load this file onto the FPGA.
To observe the output, I have SMA connections on the bladeRF which receives and send data with antennas, as shown in the picture below. I connect the bladeRF to my computer and utilize the GNU Radio software to view the output. I have successfully implemented numerous codes without the FIR II filter, where the output is clearly visible. However, when I incorporate the FIR filter, I am unable to observe any output.
Thank you,
Daoud
