Hi,
Thank you so much for your interest in our products and for using our community.
CodeWarrior is an IDE that has not been maintained for a long time, so the support we provide for this IDE is limited.
Also if you are just moving to the KL2x, I would like to mention that perhaps the LPC800 Series and MCX Portfolio may also suit your needs.
Regarding the FRDM- KL26Z, I firmly recommend you use the MCUXpresso IDE, where you will find in its SDK a wide variety of examples, including SPI examples:

Hope it helps you.
Have a nice day!
