Processor Expert support for MK22FN256VLH12?

Hi. As of today Processor expert does not support the MK22FN256VLH12 (Ver 2.0.0 of Kinetis Design Studio). PE has support for MK22FN1M0VLH12, a 1MByte variant of the same MCU. I have modified the linker script to adjust for the smaler FLASH and RAM in the 256 device, but the program then enters an exception when setting upp the MPU. I'am affraid that there might be other differences also between the 1MB and 256KB device. Is there anyone who knows if PE will support MK22FN256VLH12 soon? Alternatively is it enough to change the address map and the MPU setup to be able to use the 1MB device settings for 256KB device instead?

Hello Olav Birkeland:

The support for K22FN256 is available, but you have to install the Service Pack for K22F/KV31F.

Go to Help -> Install New software, in Work with select "Freescale KDS Update Site" and install the one called "Processor Expert Support for Kinetis K22F/KV31F @120/100 MHz Service Pack". See below:

With this you have Processor Expert support for K22FN256 and other variants of K22.

Regards!,
Jorge Gonzalez

Thanks Jorge.

I have now the correct MCU, but the problems are not over yet. I switched to the 64pin package (MK22FN256VLH12 in LQFP 64-pin package)

and then I receive the errors as can be seen from the screen capture:

Hi Jorge

I restarted KDS and then I actually godt a choice of switching to the correct package. And now it works!

Thanks!
