  1. Could you send email to xianjun.jiao@ugent.be to introduce your self? Early
  2. Our image is used directly or you build your own image? I used our image
  3. What is your own modification? Clock tree
  4. Versions: OS, Vivado, openwifi/openwifi-hw repo branch and commit revision Ubuntu16,vivado 2018.3, the latest branch of openwifi
  5. Board/hardware type E310V2
  6. WiFi channel number 01
  7. Steps to reproduce the issue, and the related error message, screenshot, etc

Hi, Dr Jiao, I wanna know why does the clock of openwifi-ip come from 9361? actually, I can not use 9361's clock for openwifi becasue the reason of reset for dma, I use FCLK from PS side(100MHz) for openwifi IP. It's work. But when I change the BW from 20MHz to 5MHz, And the FCLK change to 25MHz(It's same frequency with the openwifi-ip's clk if i use the clk from 9361). The TX side is working, but in RX side, I can not receive any packet from another E310V2. I change the BW by change the FIR file and the six parameters. Any things need to modify?

Thanks for your help.

Cordialement.
