developing a baremetal application for MKL14Z

ulivinico — Tue, 17 Sep 2013 13:46:08 GMT

I'm developing an application for MKL14Z.

May you suggest me some "starting code" or example projects for these microcontroller family to start with?

Where may I find specific header file such as "MKL14Z4.h" (not CMSIS).

Hi Ulivini Co,

The KL14 is a subset of the KL25 device.

The KL25 has board support as standalone Freedom board or as Tower kit.

Please visit: FRDM-KL25Z Product Summary Page

Click the Download page to access tools and software: FRDM-KL25Z Product Summary Page

Look for following:

KL25_SC: FRDM-KL25Z and TWRKL25Z48M Sample Code Package.

Size (K): 25760 Format: exe Rev #: 8 Modified: 7/23/2013

kl25_sc_rev8\klxx-sc-baremetal\src\cpu\headers\MKL25Z4.h is super set header to cover the KL14 as well.

Also please review this post:

Thank you. I was able to run example "low_power_dma_uart_demo".

Then I've made a new project "TESTPRJ" by using "make_new_cw_project.exe"

and I've created the directory "kl25_sc_rev8\klxx-sc-baremetal\src\projects\TESTPRJ" where I've copied the example code in "platinum".

These steps were ok and I was able to compile and debug the project.

Anyway, trying to compile other projects such as "FRDM_KL25ZDemo" I have several errors. Firstly, the files in subdirectories are not included, and this is easily solved by adding them to the project; then Codewarrior finds multiple definitions of some declaration since it finds, e.g., a second "sysinit.c".

Since it looks that I'm not following correct methods I would like to ask you which is the correct way to compile the given code? Thank you
