Linux System Programming

• Why Embedded Linux We use Linux on embedded devices because

  1. There's a lot of functionality that's already built into Linux (supporting for scheduling, scheduling threads, network stacks like TCP-IP or web, USB, WiFi, Bluetooth, Storage like flash or HDDs, etc.)
  2. It has already been ported to wide range of architectures
  3. It is open-source therefore modifiable (change the source for your needs)

• Board Support Packages (BSP) it is a bundle, usually released by Silicon or SOC vendors (Texas Instruments, NXP, STMicroelectronics etc.), with all the things that you need in order to be able to run Linux on a particular hardware and create a reference design for you so it's easier for you to get started running Linux on a specific board/hardware.
