Freescale Kinetis FRDM-KL25Z

Hardware

Platform Freescale Kinetis: Freescale Kinetis Microcontrollers is family of multiple hardware- and software-compatible ARM Cortex-M0+, Cortex-M4 and Cortex-M7-based MCU series. Kinetis MCUs offer exceptional low-power performance, scalability and feature integration.

Microcontroller MKL25Z128VLK4
Frequency 48MHz
Flash 128KB
RAM 16KB
Vendor Freescale

Configuration

Please use frdm_kl25z ID for board option in “platformio.ini” (Project Configuration File):

[env:frdm_kl25z]
platform = freescalekinetis
board = frdm_kl25z

You can override default Freescale Kinetis FRDM-KL25Z settings per build environment using board_*** option, where *** is a JSON object path from board manifest frdm_kl25z.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:frdm_kl25z]
platform = freescalekinetis
board = frdm_kl25z

; change microcontroller
board_build.mcu = mkl25z128vlk4

; change MCU frequency
board_build.f_cpu = 48000000L

Uploading

Freescale Kinetis FRDM-KL25Z supports the next uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • mbed

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:frdm_kl25z]
platform = freescalekinetis
board = frdm_kl25z

upload_protocol = mbed

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Freescale Kinetis FRDM-KL25Z has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.
