Linux kernel hacking on ZynqUltraScale+ with Petalinux

September 4, 2023

The ZynqUltraScale+ is a powerful SoC platform combining multi-core ARM64 CPUs and FPGA technology. There are plenty of projects that can take advantage of running a Linux kernel on the ARM64 processor and sometimes they require some degree of kernel hacking. In this post we will setup a build environment to modify the Linux kernel, compile it, and run it rapidly on a ZCU106 development board. For this we want the following : Be able to modify and compile the…

An ARM single board computer as PCIe card !?! (part 1)

In this blog post series I will show how we can use an ARM single board computer (SBC) as a PCIe card (PCIe endpoint). At REDS when developing PCIe based devices we usually rely on FPGAs, for example to develop FPGA PCIe accelerators. These are often based on existing PCIe cards from AMD (Xilinx) and Intel (Altera). For example the Xilinx Alveo series or Zynq based development boards. To develop accelerators such cards are fine and the development boards allow…
