Domestic zynq standalone pl-ps interrupt commissioning

1、 Background introduction

At present, it is made in China ZYNQ Substitute import xilinx ZYNQ, In the debug PL-PS When it's interrupted , And import Xilinx ZYNQ There's a difference , Record the following .

2、vivado engineering

Introduce a GPIO Input ZYNQ PL-PS

ZYNQ Middle configuration PL-PS interrupt

 

 

here vivado The project configuration is finished

3、procise engineering

Due to domestic ZYNQ With imports ZYNQ There is still a difference ,PL-PS The interrupt number of is different from that of import , Need to be in procise View the actual interrupt number in .

Procise from vivado Import file in , Produce domestic ZYNQ Hardware connection relationship , Click... After importing ZYNQ Can see PL-PS The interrupt sequence number of has changed

 

Domestic front 8 An interrupt number is from 57-64, What is imported is from 61-68.

4、SDK Code

from procise Export project to IAR in , The code is as follows , The interrupt mode is triggered by the rising edge .

/*
 * helloworld.c: simple test application
 *
 * This application configures UART 16550 to baud rate 9600.
 * PS7 UART (JFM_QL_PS) is not initialized by this application, since
 * bootrom/bsp configures it to baud rate 115200
