  1. I got the problem with AXI-Lite interrupt on pentalinux. So i try to create a simple PS-PL system as shown in image below

    The multiplier was created by AXI-Lite and asynchronous circuit, so the interrupt signal of multiplier was sent when it compute finish. This system work well on bare metal(No OS).

    However, I need to create petalinux application to interface PL but Linux did not identify interrupt of multiplier as shown in image below.

    so i already config linux kernel to enable "Userspace platform driver with generic irq and dynamic memory" and I edit some system-user.dtsi file as below.

    The spi,i2c, uart, and AXI-lite work well on petalinux. I can send data to PL with AXI-lite with memory map (mmap) but i can not handle the interrupt signal of multiplier.

    I do not know, what's the problem and nobody provides a tutorial of AXI-lite and interrupt handler on petalinux.

     

  2. I'm a newbie who is using a Zybo-z7010 with BLE Pmod module, it can work without OS.

    However, it doesn't work anymore when I try to run it on Petalinux following example as bellow :

     https://xilinx.github.io/Embedded-Design-Tutorials/docs/2020.2/docs/Introduction/Zynq7000-EDT/4-linux-for-zynq.html

    Can any Pmod modules work on Petalinux with  Zybo-z7010 ?

    If it can be done how to do it or do you have a tutorial?
