Requirements

Prerequisites

  • Basic familiarity with using a GNU/Linux system (e.g. Ubuntu) as an end user in user space
  • Basic familiarity with a command line shell
  • Basic knowledge of user/kernel space programming with GNU/Linux
  • Intermediate C programming knowledge
  • You should have attended Embedded GNU/Linux Systems Architecture (5 days)  (strongly recommended!) unless you are already familiar with the material presented in those trainings.
  • You actually need to have experience with Embedded GNU/Linux (kernel, userspace, root file system, tools) to follow the Yocto training.
  • It might be helpful if you attended Embedded GNU/Linux Device Drivers and Kernel Internals (5 days), but that’s not really a prerequisite. It’s sufficient to know how to build the GNU/Linux kernel, kernel drivers in/out of tree and the fdt from the kernel side of things to follow the Yocto training.
