eCos Support for the ST Microelectronics STR7XX ARM microcontrollers -- Overview
Description
The ST STR7XX series of ARM microcontrollers is supported by eCos
with an eCos processor variant HAL and a number of device drivers supporting
some of the on-chip peripherals. These include device drivers for the
on-chip flash, serial and watchdog devices. In addition it provides
common functionality and definitions that STR7XX based platform ports
may require, as well as definitions useful to application developers.
This documentation covers the STR7XX functionality provided but should be
read in conjunction with the specific HAL documentation for the platform port.
That documentation will cover issues that are platform-specific and are
not covered here, and may also describe differences that override or
supersede what the STR7XX variant HAL provides. The areas that are specific
to platform HALs and not the STR7XX variant HAL include:
memory map and related configuration and setup
memory remapping
Clock parameters
GPIO setup
Any special handling for external interrupts, or additional interrupts
