eCos Support for the Atmel AT91SAM7 Processor Variant — Overview
This document covers the configuration and usage of the Hardware Abstraction Layer (HAL) for the Atmel AT91SAM7 processor family which includes the AT91SAM7S, -X an -A series. It is expected to be read in conjunction with platform HAL-specific documentation, as well as the eCos HAL specification. This HAL package complements the ARM architectural HAL, AT91 variant HAL (where appropriate) and the platform HAL. It provides functionality common to all AT91SAM7-based board implementations.
This support is found in the eCos package located at
the eCos source repository.
The AT91SAM7 HAL package is loaded automatically when eCos is configured for an AT91SAM7-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 Atmel AT91SAM7 within this processor HAL package include:
Support for the interrupt-driven serial, SPI, watchdog and wallclock (RTC) features of the AT91SAM7 are also present and can be found in separate packages, outside of this processor HAL.
