which Tutorial for Linux PL access

Former Member

Hi,
i just worked trought the beginner ZedBoard Vivado Workshop, now i know how to access GPIO Ports via bare metal applications.
But i want to use Linux as OS, do you know a good beginner Tutorial about the same stuff for Linux? I want to access Switches/LEDs and a SPI Device from Linux.

Thanks a lot

    Now i want to go a little bit further with my zynq design.
    I created my own ip core on the fpga, so now i need a way to comunicate with that ip from my linux system. i read that there are severals ways to do this (UIO,loadable kernel modules/dev/mem/sysfs etc.) but which one is the fastest and best one? i know that petalinux can create and include loadable kernel modules but i dont found any good documentation about that function and how it works.  
    Could you show me a good way to solve this basic problem to communicate between pl and ps. with a baremetall application this is so easy why not for linux....

    thanks
