Getting started with Kinetis-MCUs

info13 — Thu, 10 Oct 2019 00:13:01 GMT

Hello there! These days, I´m getting started with my first 32-bit MCUs, and for fiddling, I´m using a FRDM-KL25Z Board.
For the moment I´m haveing some questions. I´m coming from AVR 8-bit MCUs.

→ There´re seeming to be different types of Binary-Machinecode files. *.bin as well as *.axf and I think I saw others, too. What does that mean, only a different ending or more like different encoding or other reasons?

→ So far, I discovered two ways to create Firmware for the KL25Z: Programming with the functions from the Kinetis-SDK and using the M-Bed online-Compiler. Why can´t I use the SDK-Code in M-Bed and vice-versa? Are that just two different libraries? Where can I download them separately if I want to build completely manually (commandline-gcc + texteditor)?
Or is M-Bed an OS and I program the MCU not at all "bare metal" when using M-Bed?

→ Is there a good documentation giving an overview over all the different possibilites of creating software for the MCU-family?

Thanks for your hints!!

Hi Jan,

when you download SDK, there is also SDK document. Please read "getting started with MCUXpresso SDK". It will help you to understand tools/SDK/openSDA/IDE.

Jing

That helped me a lot, thank you!

The other question very important to me: Is the M-Bed Online Compiler, compared to the KSDK/MCUXpresso-way, also bare-metal / directly-on-the-hardware programming? So M-Bed isn´t more than a big, nice Software-Library with an online C compiler?

Or is an OS utilized (MBed-OS) in general as the platform for all programs?
