device tree generation

100aditya
100aditya over 9 years ago

Dear Sir,
              I am following the scripts at  http://microzed.org/product/wilink-8-adaptor. I am trying to integrate the Wilink8 WiFi  module with the ZedBoard. Slowly-slowly i have progressed up to a point where now mine next step is to generate the device tree for the ZedBoard.What i confused now is that:- From various sources on the internet the prebuilt device tree(dts) is availble . So mine first question is:-
1- Can i use that directly?? but at the same time it seems that i can not because these device tree are not including the wilink8(wifi) module in their dts file.

2- So , in the case i can use those prebuilt dts file then please guide me how to modify that.

 3-And ,if i can not use those prebuilt dts files then also please guide me how to built the new dts file for mine purpose.

4- Is there any tutorial on creating the device tree for the ZedBoard.

Regards

Aditya

    Hi Josh,

      Actually  i read the content of the webpage suggested by you and also i found one more useful link  http://xillybus.com/tutorials/device-tree-zynq-1 and they both gave me insight of device tree. Now i have two options:-

    1- I got one device tree .dts file form the http://architechboards-zedboard.readthedocs.org/en/latest/quick.html webpage. So should i use this directly and only add mine needed drivers in this. Or

    2- Should i start from scratch as per website http://www.wiki.xilinx.com/Build+Device+Tree+Blob and generate a new device tree.

    What i want to ask/confirm that:- device tree(.dts) file is not project specific and the content of .dts file will be unique for the particular board(which is in our case is ZedBoard). So i can take one working .dts file(as in option 1) and add mine device node in this .dts file(if it is not there) and it will work ????

    Please suggest me .

     

    Regards

    Aditya
