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.
