In this brief demo we will discuss how to write your interrupt handler to support nested interrupts on the Microblaze.
Table of Contents
Design files:
The design files for this demo can be downloaded here:nested_int_ex.zip
Hardware:
Here two AXI timers are used to generated the interrupts.To build the hardware, launch Vivado 2018.1, and source the TCL script below from the TCL console in Vivado:
- source data/all.tcl
Software:
The software is built using XSCT commands to build the SDK workspace. This will be ran from the TCL command in the previous step.The code can be explored at repo\sw_apps\nested_ex\src\nested_ex.c in particular the tmrctr_1_handler on line 91
