How can I generate device tree for KC705 & AD6676 setup?

 Hi,

 

I have a KC705 & AD6676 setup. I'm using analog devices's reference design that is working on microblaze.

I need to generate a devicetree(dts&dtsi) for my setup.

I tried to modify already exist dts files but It could not work properly.

 

Analog devices's repo have many dts files for different board&fmc double.

I used "vc707_ad6676evb.dts" and "vc707_ad6676evb_pl.dtsi" as base devicetree reference.

I merged base dts files with KC705&Ad9467' dts files(kc705_ad9467_fmc.dts and kc705_ad9467_fmc_pl.dtsi).

AD9467 uses LPC and AD6676 uses HPC. I think, I made a mistake related with FMC slot.

I only replaced Ethernet related lines in vc707&ad6676 wtih KC705&AD9467 dts files.

After generating new device tree(attached), and installation, I can ping board from PC but I could not list any device on board with iio_info command(dmesg and iio_info result is attached.)

 

In conclusion, I could not modify dts files properly.

 

I searched in your forum. Xilinx has devicetree generator tools but most of people say: There are many problems in new version of generator. You have to use old version. It  works fine ...

 

I want to ask you: What is the best way for generating devicetree? You recommend which way?

Please guide me. How can I use this tool, or tcl script...

 

Thanks in advance.
