Summary: This short tutorial, first, defines the petalinux, board support packages (BSP) and quick emulator (QEMU) used in zynq 7000 linux programming. It, secondly, describes the steps necessary to install petalinux on Ubuntu PC. Finally, an example on how to run and test the petalinux based linux system in QEMU is demonstrated.
1. Definitions of Petalinux, BSP and QEMU: Petalinux, which is based on the yocto project, is a Xilinx development toolchain which provides us everything necessary to build, test, customize and deploy an embedded linux system. Furthermore, it is an embedded linux distro maintained by Xilinx and targets Xilinx System on Chip (SoC) designs. It also has an integrated full system quick emulator (QEMU). Developers can test and verify the customized linux solution on QEMU before deploying it on the actual hardware. Additionally, Xilnix also provides Board Support packages (BSP) for various Xilinx evaluation boards. A BSP describes the various hardware features supported by the corresponding evaluation board. Petalinux uses these BSPs to configure the kernel as per specification defined in them. Read more
