Petalinux

PetaLinux is source-based hardware and software distribution which has been developed specifically for using Embedded Linux on reconfigurable logic devices. The PetaLinux distribution includes everything needed to easily create Linux systems running on Xilinx field programmable gate arrays (FPGAs).

PetaLinux is developed and maintained by PetaLogix. PetaLinux builds upon and extends the well-known uClinux-dist build environment that is maintained by SnapGear.

Picoblaze start

Si se tiene un kit de desarrollo de Diligent basado en una FPGA Spartan, hay una nota de aplicación de Xilinx que explica como usar el display de LCD que trae dicho kit, cuyo uso está implementado usando Picoblaze. Este documento está bueno como para empezar a jugar un poco con esta tecnología y entender el uso del kit y Picoblaze.
