communicate the 2 ARM and PL ?

vaijwade
vaijwade over 8 years ago

Dear all,

 

 I am working with zed board(ZC7020) and i have a question in my mind.The question is "it's possible to implement a simple communication read / write from the 2 ARM processor's and the PL" ?

                   In other way, i want to make the first ARM write something into the PL ( maybe via a register ) using the AXI bus, and the second ARM will read this message and print it on console. I hope it is possible but i don't know how to proceed to achieve this. if some one tried this before suggest me with a document or reference design?

    Hello Vajwade,

    I am going to suggest you take an approach of having one processor talk to the other directly as they share the same memory space. This method is much easier then the path you are refering to above.

    Hello Vaijwade,

    Take a look at the Developing Zynq Software Speedways we offer

    http://zedboard.org/course/developing-zynq%C2%AE-7000-all-programmable-soc-software-vivado-20133-201441-20152-and-20162

    In one of the last labs we have the two processors communicate with eachother to turn them off and on.
