Ok, so I had spent a tremendous amount of time learning how to use KDS, the Kinetis processors, and Processor Expert. It has been a couple of years now and I actually have forgotten most of what I had learned. Now we have to deal with MCUXpresso / FreeRTOS (was previously using KDS, KSDK, and MQX) and I wouldn't be surprised if we have to re-write a bunch of our code.
I'm going to start from scratch. I'm obviously going to google this a lot, but for the active community members here, are there any primers that you would recommend? Another alternative is to just jump in fresh and start over, and look up answers for all of the problems I encounter as they come up.
