Zephyr: FDRM_K64f board from NXP

Florian Fouillet <Florian.Fouillet@...>
 

Hi,

 

I am currently working on the Zephyr OS with a FDRM_K64f board from NXP. I am just going through the documentation and the code example for now.

I have trouble to understand where is the implementation of the macro for the Freedom board. For eample in the blinky project example (zephyr/samples/basic/blinky/src/main.c) we have a #define LED LED0_GPIO_PIN. we should have somewhere the definition of this LED0_GPIO_PIN to match with the board I am using. however I don't know where is this implementation. In addition of that, do you know where I can find a list of every define like this LED0_GPIO_PIN. For example for PWM or SPI or UART?

It is done somehow through DTS, you need to search i.e.
./zephyr/include/generated/generated_dts_board.h

Take a look at the documentation to understand how this process works:

Thanks everyone, I will have a look at the DTS.

 

Cheers,
