CYGPKG_HAL_CORTEXM_KINETIS — eCos Support for the Kinetis Microprocessor Family


The Freescale Kinetis K 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, I²C, SPI, Ethernet, RTC/wallclock and watchdog devices. In addition it provides common functionality and definitions that Kinetis based platform ports may require, as well as definitions useful to application developers.

This documentation covers the Kinetis 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 Kinetis variant HAL provides. The areas that are specific to platfom HALs and not the Kinetis 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
