Hi Ilija,

I have made some tests and in order for the driver to work, I desactivated the
"Redboot FIS support" (in Redboot ROM monitor -> Allow RedBoot tu support FLASH
programming) and desactivated the "Keep Redboot configuration data in flash"
option.
When this options are enabled, Redboot try to read a portion of flash  (with a
memcpy) which leads to a problem.

I also try to move the CYG_FLASH_DRIVER into a new kinetis_flash.c file and add
it to the file to be compile in the .cdl file. Redboot builds fine with it but
when I launch it, it seems that there is no flash init done. I'll keep working
on that but if you have any idea of what I am missing ...
