Running Blinky RKH demo on Freescale ARM Cortex-M0F demostration board

FRDM-KL25Z Kinetis KL2. This is a guide to how to setup and use the demo board to evaluate the RKH framework. It assumes a prior knowledge on board features and development environment.

Blinky demo BSP

  • Blink state is shown through target board D3 RGB led on PA[4].
  • Tracing info through UART0_TXD assigned to PA[2] connected to Open SDA usb to serial port at 115200 8N1.
  • LPTMR0 at LPO clock 1Khz is used to trace time stamp.
