ad9361_probe: failed to register debugfs

That's because CONFIG_DEBUG_FS is not enabled in your kernel.

Can you share you device tree and kernel config?

Looks like the cf_axi_dds driver is not instantiated

  cf_ad9361_dac_core_0: cf-ad9361-dds-core-lpc@79024000 {
   compatible = "adi,axi-ad9361-dds-6.00.a";

-Michael

The device tree provide can't be complete -

ad9361_drv 88020 0 - Live 0xbf06f000
cf_axi_adc 12035 1 ad9361_drv, Live 0xbf068000

this shows cf_axi_adc - but there is no relevant snippet in the tree you provided.

With the given information - it's hard to tell what might be wrong.

-Michael

There is one physical ad9361 IP block mapped to 0x79020000 - however logically it's split internally in an receive and transmit block. Two different drivers take care of it. The offset to the transmit block is 0x4000.

cf_ad9361_adc_core_0: cf-ad9361-lpc@79020000 {
        compatible = "adi,axi-ad9361-6.00.a";
        reg = <0x79020000 0x6000>;

cf_ad9361_dac_core_0: cf-ad9361-dds-core-lpc@79024000 {

        compatible = "adi,axi-ad9361-dds-6.00.a";
        reg = <0x79024000 0x1000>;

forget about the auto generated device tress completely.

In most situations they are not working properly. Yes add is manually.

Hi,

Now, I enabled the debugfs in the kernel config. Below are the dmesg, device tree and kernel config  after updation.

Hi,

And, I am not using DMAs in my design, Please find the tcl file below for reference.

system.tcl - Google Docs 

Thanks.

Hi,

I have shared all the dts*  files in my /$project/subsystems/linux/configs/device-tree. Please check it again. What other information should I provide?

This cf_axi_adc  driver is  added in the kernel. I believe that corresponds to ad9361 ipblock in the design.  I verified the address of the axi-ad9361 ipblock.

The below lines are snippets from the zynq-zc702-adv7511-ad9361-fmcomms2-3.dts

cf_ad9361_adc_core_0: cf-ad9361-lpc@79020000 {
        compatible = "adi,axi-ad9361-6.00.a";
        reg = <0x79020000 0x6000>;
        dmas = <&rx_dma 0>;
        dma-names = "rx";
        spibus-connected = <&adc0_ad9361>;
        xlnx,dphase-timeout = <0x8>;
        xlnx,num-mem = <0x1>;
        xlnx,num-reg = <0x1>;
        xlnx,s-axi-min-size = <0x1ff>;
        xlnx,slv-awidth = <0x20>;
        xlnx,slv-dwidth = <0x20>;
        xlnx,use-wstrb = <0x0>;
    };

cf_ad9361_dac_core_0: cf-ad9361-dds-core-lpc@79024000 {

        compatible = "adi,axi-ad9361-dds-6.00.a";
        reg = <0x79024000 0x1000>;
        clocks = <&adc0_ad9361 13>;
        clock-names = "sampl_clk";
        dmas = <&tx_dma 0>;
        dma-names = "tx";
        dac-sample-frequency = <491520000>;
        xlnx,dphase-timeout = <0x8>;
        xlnx,num-mem = <0x1>;
        xlnx,num-reg = <0x1>;
        xlnx,s-axi-min-size = <0x1ff>;
        xlnx,slv-awidth = <0x20>;
        xlnx,slv-dwidth = <0x20>;
        xlnx,use-wstrb = <0x0>;
    };
};

Considering this:

cf_ad9361_adc_core_0: cf-ad9361-lpc@79020000 { :

compatible = "adi,axi-ad9361-6.00.a";
79020000 is the physical address of the ad9361 ip block in the bare metal design.

I used the same bare metal design. So I believe, the lines below also represent the same ad9361 ip block with same physical address.

axi_ad9361:  axi_ad9361@79020000:  {

          compatible = "xlnx,axi-ad9361-1.0";

          reg = <0x79020000 0x10000>;

      };

  cf_ad9361_dac_core_0: cf-ad9361-dds-core-lpc@79024000 {   (mentioned above )

But there is no IP block with this physical address(79024000). What does this correspond to?

 Should I add the above lines from zynq-zc702-adv7511-ad9361-fmcomms2-3.dts corresonding to the ddscore to my device tree, in the same way I added gpios and adi-fmcomms2.dtsi file to the system-top.dts?

cf-ad9361-dds-core-lpc@79024000:  and what IP block does this correspond to in the bare metal design. what does this core do?

and how do I instantiate, If I need the dac core/ddscore s for the wrking of my design .

Thanks in advance!!!

But the lines corresponding to the transmit block  are not generated in  the device tree, even though physical ad9361 ip block is present in the block design.

       cf_ad9361_dac_core_0: cf-ad9361-dds-core-lpc@79024000 {

        compatible = "adi,axi-ad9361-dds-6.00.a";
        reg = <0x79024000 0x1000>;

should I add it manually?

 Also,  You said : Looks like the cf_axi_dds driver is not instantiated. How do I instantiate it?

Not sure about your HDL modifications. However the DAC-DDS core may be setup to generate a DDS tone.

You can control the DDS tones using the out_altvoltageX_* attributes.
