PS GPIO. The Zynq device has up to 64 GPIO from PS to PL. These can be used for simple control type operations. For example, in the base overlay, the PS GPIO wires are used as the reset signals for the IOPs. The PS GPIO are a very simple interface and there is no IP required in.

However, there are situations that need to be handled by the application running on the PS such as fabric interrupts from custom IP in the programmable logic. To demonstrate how interrupts from the PL to the PS can be addressed in PYNQ, I put together a simple hardware project which connects the push button switches and the four LEDs to the processor system. There are two configurable PS to PL AXI interfaces. One is from the FPD to the PL (via the LPD). The other is from the LPD to the PS. The interface parameters and the PS-to-PL AXI interface attributes are listed in the following table. The two PS to PL interfaces are mapped within the low 4 GB memory address space. Tab. Re: PL to PS interrupt:how to acess in arm processor hi, thanks for the replay niciki. i have a xc7z010 400g class 1 soc on my board . like other boards i dont have a usb jtag or serial cable . so i think i cant use sdk tools. so i was using memory map functions to map the output of PL to PS and getting the value in my linux running on the sd card. Use PS HPM LPD AXI to control the AXI interface of the GPIO and timer. Connect interrupt signals. Enable the PS AXI HPM LPD AXI interface: Double-click the Zynq UltraScale+ MPSoC IP block. Select the PS-PL Configuration tab. Enable AXI HPM0 LPD, expand it, and set the AXI HPM0 LPD Data Width drop-down to 32 bits. Click OK to close the window. With the PS implemented and configured for the MicroZed, we need to reconfigure the PS to enable the PS to PL interrupts. On the interrupts tab, enable the fabric interrupts and scroll down the list to GPIO processor to fabric interrupt. Add in an ILA and connect it to the IRQ processor to fabric interrupt in the block diagram. Then, when an interrupt occurs, the DMASR register can be read and stored somewhere, and then the normal Xilinx interrupt handler can be invoked. This is of course a pretty hacky solution. Additionally, since the IRQ handler is declared as static by the Xilinx driver, this would either need to be removed with a patch, or the Makefile would have to pass the.

I would like the PL to couse an interrupt every time the counter is incremented and interrupt the PS so that it calculates the ARCTAN of the counter value then send the result to the PL to be stored in another register for furthur processing.

These are shared interrupts from PL logic to GICs of Real-time Processing Unit (RPU) and Application Processing Unit (APU). High priority PL to PS cores (Processor) These are Legacy FIQ/IRQ interrupts for RPU/APU from PL. One IRQ and FIQ per CPU will be routed from PL to GIC. There are two configurable PS to PL AXI interfaces. One is from the FPD to the PL (via the LPD). The other is from the LPD to the PS.The interface parameters and the PS-to-PL AXI interface attributes are listed in the following table.The two PS to PL interfaces are mapped within the low 4 GB memory address space.; The Xilinx analog mixed signal module, referred to as the XADC ,. . ILA confirmed the pulse. The application is supposed to count 50 interrupt events and quit. However, no triggering is happening. Clock freq is 50 MHz and a counter is 16 bit. The C-code is taken from two sources: Xilinx Timer-interrupt example and Avnet interrupt tutorial controlling brightness with PWM. The last time I did this (with Vivado 2019.1) two bad things happened: #1, the dangling input read high all the time, so if it gets enabled you get in a loop unless the input is set for edge sensitive. #2 and probably your issue, the hardware export enumerated the IRQ number wrong. It just skipped the unused input so was one or two off.

The Xilinx analog mixed signal. Since we can connect interrupts from enabled peripherals in the PS to the PL, this means we can create a more responsive system if PL action is required for a specific PS subsystem. It is not necessary for the processor to first receive the interrupt, process it, and then trigger action in the appropriate PL module. For this project, we are. I successfully implemented a PL->PS interrupt in a baremetal environment using the tutorials. Now I thought porting it to FreeRTOS would be straight forward but once the task scheduler runs I can't get any interrupt fired. I'm sure I'll just have to link my ISR to some FreeRTOS Task/function but can't find any hints on how to do so. I would. peripherals in the PS and the PL.
