i.MX35 board initialisation and memory mapping using the Linux target image builder (LTIB)

Posted: 26 Apr 2010     Print Version  Bookmark and Share

Keywords:memory mapping  Linux kernel  LTIB i.MX35 board 

This application note provides general information regarding the board initialisation process and the memory mapping implementation of the Linux kernel using the LTIB in an i.MX35 Board Support Package (BSP).

The board initialisation process is relatively complex and long. Hence this application note provides a general overview of board initialisation process, while explaining more about the memory mapping. The knowledge on these aspects enable better understanding of the BSP structure. When changes such as migrations to another board or device with different memories and external board chips are needed, these are some of the elements that need to be changed on the software side.

This application note is targeted to the i.MX35 BSPs, but it is applicable to any i.MX device. The structure and architecture of the system (software) is the same for all the i.MX BSPs.

This application note covers information, and the initialisation process flow of a BSP running a LTIB, on an i.MX35 platform. The focus of this application note is on memory elements and memory mapping, from bootloader start-up to kernel initialisation.
