I am kind of new on RTOS. I am trying to use Yocto project on dev board FRDM - KW41Z. What meta layers should i use to create an basic image? Is there any example using a dev board with ARM processor?
Unfortunately we do not have any example available.
Yocto is a tool intended to create a Linux-based system and the kinetis and LPC mcu's can't support any linux os because of the hardware requirements.
For RTOS I recommend to download our SDK, that SDK can be built to include the FreeRtos
For more information about FreeRtos please refer to the reference manual: https://www.freertos.org/wp-content/uploads/2018/07/FreeRTOS_Reference_Manual_V10.0.0.pdf
Let me know if this helps.
