Can we use the code for K series MCU in the L series MCU?

[pratiekbhadrana]

Hello,

We purchased dev boards for the K series MCUs. But now we have decided to use the L series Cortex M0 MCUs. If we consider only the peripherals common to both families, can I test the code on the FRDM K64 and later convert it for use in the KL04?

I am using KDS 3.0.0 with Processor Expert. Not using KSDK.

Thanks

Hi

It depends on the software that you are using. There are a lot of differences between K and KL families (different peripheals, different clocks, different registers, different Flash) so the code tested on a K64 will not run on a KL part without appropriate adaptation.

It is possibe to write the HAL (hardware application layer) so that applications are compatible but the drivers below the HAL have to be modified in many cases to acheive this. You cannot write and test these drivers on a K64 when they are destined for KL parts. They need to be tested on appropriate KL parts.
