Support for the Freescale i.MXxx Processor — Overview
This document covers the configuration and usage of the Hardware Abstraction Layer (HAL) for the Freescale i.MXxx processor family. It is expected to be read in conjunction with platform HAL-specific documentation, as well as the eCos HAL specification. This processor HAL package complements the ARM architectural HAL, ARM9 variant HAL and the platform HAL. It provides functionality common to all i.MXxx-based board implementations.
This support is found in the eCos package located at
packages/hal/arm/arm9/imx within the
eCos source repository.
The i.MXxx processor HAL package is loaded automatically when eCos is configured for an i.MXxx-based platform. It should never be necessary to load this package explicitly. Unloading the package should only happen as a side effect of switching target hardware.
Supported features of the i.MXxx processor within this processor HAL package include:
Support for the on-chip SPI device, SPI NOR flash, I²C, interrupt-driven serial, Ethernet and watchdog features of the i.MXxx are also present and can be found in separate packages, outside of this processor HAL.
