I tried to disable keeping Redboot configuration data in FLASH bit it still raises exception. Can you post your ECM file?

Probably the object file containing CYG_FLASH_DRIVER has been discarded by the linker since effectively there aren't references to it. If the driver is general for all Kinetis devices you can leave it in kinetis_misc.c or put it in kinetis_flash.inl and include in kinetis_misc.c. Otherwise you can put copies in platforms (see STM32 for example). However driver inclusion for compilation should be conditional with some #ifdef.
