Chapter 9: Sending an Interrupt from PL to PS for Xilinx Zynq Ultrascale+ MPSOC
In chapter 2, we create a block design that includes PS of MPSOC and AXI GPIO/Timer in PL. In this block design, AXI GPIO and AXI Timer can’t issue interrupt events to PS because the interrupt signals of AXI GPIO and AXI Timer are floating. Now we want AXI timer can send an interrupt signal to PS in this tutorial. An example C code to handle this interrupt is also listed in this tutorial.
1. Open the block design created in chapter 2 then connects AXI timer’s interrupt port to MPSOC’s pl_ps_irq. The result should be:
