I was trying in to build and upload an Kinetis Bootloader 1.2 on the respective MCU but with no success! I find impossible to adapt official bootloader to this MCU family. As an alternative I proceed with uTaskerSerialBootloader. As I have read, when KBOOT_LOADER is enabled, it should be compatible with Kinetis Updater application!
I have followed the indications from the guide: http://www.utasker.com/docs/uTasker/uTaskerSerialLoader.PDF
I have tested the following two configuration in config.h one by one:
As the board I am working with is a custom one, I have also forced bootloader mode this way:
#define FORCE_BOOT() (1)
I have followed the manual when I imported the project and everything seems to be fine!
I have also checked baudrates and other UART configuration in app_hw_kinetis.h and the port is selected correctly connected!
Does anyone have experience with this? Is there any other special requirement to do make it works?
