ad9361 more than two ip

Question asked by hammerclavier on Feb 20, 2017
Latest reply on Feb 22, 2017 by hammerclavier

I am trying to add 3 axi_ad9361 ip to my Picozed SDR SOM board and so far has been able to do only 2 based on FMCOMMS5 devicetree design, but not 3.

 

I made sure that hardware is ok as well as PL side to connect the SPI channels. Is there anything on the Linux Kernel rather than devicetree to be modified?

 

here is a snippet of my device tree:   -------> ad9361-phy-C@2
