Hi everyone, I'm trying to build a simple system on the Digilent Zybo board which lights up a LED when the Switch below is turned on. In the ISR the interrupt gets cleared via a register in the FPGA. 5µs. I am facing some troubles to clear the interrupt in the PS side after the handler has attended the interrupt, as a result the handler function is continuously being triggered. UG1165 (v2015. All interrupt requests, whether they are PPI, SGI or SPI, are assigned a unique ID number which is used by the interrupt controller to arbitrate. The examples are targeted for the Xilinx ZC702 rev 1. With Zynq-7000 APSoC you need to use the Concat block, and I assume it is the same with MPSoC. ZC702 Rev 1. With interrupt priorities of 0x18, 0x10, and 0x08, the BPR needs to be set to 0x02 to ensure 0x10 can pre-empt 0x18. May I know if the interrupts are external to Zynq? Try to connect the interrupts of IPs which are inside the PL and see that there will be expected behavior. In this chapter, you will create a design with: Create a C program for blinking the LEDs and reading the switches that are connected to AXI GPIOs.

The handler for the interrupt on button-down executes the power down function and Zynq 7000 DPU TRD Introduction This tutorial demonstrates how to build a custom system that utilizes the 1. PL logic) we’ve added or removed, 61665 - Zynq-7000 SoC, I2C - Missing I2C Master Completion Interrupt Number of Views 2. com 6 After the timer expires, the timer interrupt is triggered. However, all the principles described here can be used on any other Zynq-7000 board. The creation of a Zynq device system design involves configuring the PS to select the appropriate boot devices and peripherals. The latency is about 2. 1. - The interrupts are firing based on axi gpio 0 (which is connected to my pushbuttons), - My PWM block is outputting a PWM waveform that triggers the interrupt (I soldered a jumper wire from the PWM output [pin A0] to BTN0 on the board) My interrupt handler toggles the pin outputs on AXI Gpio 2, so I can see when the interrupt is firing. Find documents on the Xilinx Product Support Website. Zynq-7000 AP SoC: Embedded Design Tutorial. This is the online home of The Zynq Book, designed to raise awareness of the book and host the accompanying tutorials.
