Integrating FFT with ADRV9009 hdL project

Are you using No-OS or Linux?

We are using no-os

Are you using the Xilinx or ADI DMA?

-Travis

We are using xilinx dma. We are following the example from below mentioned link

We are using Xilinx DMA.

To use FFT, we are following procedure from following link

Today, we have done one more experiment. From ADRV9009 HDL project, we deleted all modules and ports, except zynq processor and  added FFT example modules into the block diagram. Then we repeated all the steps to create .xsa file. Then we used .xsa file to create Vitis project for FFT.

FFT example has the same issue that DMA interrupts are not captured. C software sticks in a loop waiting for the DMA (FFT) interrupts . Can anyone help me in this regard?

I'm sorry but since there is no ADI authored code, you really need to ask for Xilinx support here. As its Xilinx's example, it should be straightforward for them to address.

During my work, i have found that it is not Xilinx DMA core problem. I have deduced that it is some interrupt configuration issue in Zynq. From ADI HDL code, i deleted all the modules except Zynq. Then i added FFT module in the HDL and connected with the Zynq processor created from ADI HDL. The FFT module provides 2 interrupts to the Zynq and Zynq fails to capture interrupt and Zynq fails to capture interrupt, as described previously.

However, I have observed that when i connect one of the interrupt to the Zynq, it successfully captures interrupt. Therefore, i feel it is some interrupt configuration issue in Zynq.

Does anyone has any idea about solving this issue?

Please direct this question to Xilinx's support.

We have solved the problem. Problem can be solved by commenting following PS interrupt settings in the file zc706_system_bd.tcl
