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?
