Procedure to add uClk_usr in Streaming DMA AFU

I want to run my AFU in uClk_usr domain in the Streaming DMA AFU sample example. Please can you provide the steps that need to be followed in order to achieve this. Thank you

Hi,


It looks like the PCIe IP is using PCLK and the AFU is running using uclk_user which is not able to match the frequency. You will need to implement clock crossing to make sure that the clock is able to pass to the AFU design without any issue.
