Embedded Design with PetaLinux Tools

Training Duration: 2 days

Course Description

This intermediate-level course provides embedded systems developers with experience in creating an embedded Linux system targeting a Zynq® UltraScale+™ MPSoC processor development board using PetaLinux Tools.

The course provides experience with:

  • Building the environment and booting the system using a Zynq UltraScale+ MPSoC with PetaLinux Tools on the Arm® Cortex®-A53 processor
  • Using open-source embedded Linux components
  • Configuring the Linux environment and network components
  • Debugging embedded Linux platforms.

The primary focus is on embedded Linux development in conjunction with the Xilinx tool flow.
