i.MX51 board initialization and memory mapping using the Linux target image builder (LTIB)

Keywords:memory mapping? Linux target image building? i.MX51 board initialisation?

This application note provides general information regarding the board initialization process and the memory mapping implementation of the Linux kernel using the LTIB in an i.MX51 board support package (BSP).

The board initialisation process is relatively complex. Hence, this application note provides general overview of the board initialisation process, while explaining more about the memory mapping.

The knowledge of these aspects enable better understanding of the BSP structure. When changes such as migrations to another board or device with the memories, 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.MX51 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 the information, and the initialization process flow of a BSP running a LTIB, on an i.MX51 platform. The focus of this application note is on memory elements and memory mapping, from bootloader startup to kernel initialization.
