While porting an application from TI´s MSP430 to the Kinetis KL15, I came to the point of porting the flash access routines. I am placing my configuration data in flash, this is working fine on the MSP430.
I am used to (read) access the flash memory like I would access data in RAM. As the Kinetis has a von Neumann Architecture (i.e. single memory area for both program and data memory), I had expected the same to be true for the Kinetis. However, what PE generates does not quite look like a simple memory access.
It was really convenient to use flash memory like RAM when reading, I am not exactly eager to copy everything into RAM before being able to use it. It means extra code and extra RAM. Is there a chance to access some user flash area with a simple read access? If yes, how? If not, what is the problem?
