CYGPKG_HAL_CORTEXM_LM3S — eCos Support for the LM3S Microprocessor Family


The Luminary LM3Sxxxx series of Cortex-M 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 LM3S based platform ports may require, as well as definitions useful to application developers.

This documentation covers the LM3S 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 LM3S variant HAL provides. The areas that are specific to platform HALs and not the LM3S variant HAL include:

  • memory map and related configuration and setup
  • Clock parameters
  • GPIO setup
  • Any special handling for external interrupts, or additional interrupts
  • Diagnostic I/O baud rates
  • Additional diagnostic I/O devices, if any
  • LED/LCD control
