This Freedom board is based on the KE15Z256VLL7 which is a 72MHz device from the 5V robust KE family with Cortex-M0+ core. This KE15 device has 256k Flash [plus 32k FlexNVM] and 32k SRAM and is in a 100 pin LQFP package, whereby the KE15 is also available in 64 pin LQFP and its memory ranges from 128k..256k Flash and 16k..32k SRAM. There is an 8MHz crystal on the board for clocking the part.

Full details and documentation for this board can be obtained from the Freescale web site: FRDM-KE15Z

To configure the µTasker project for this board simply enable the define FRDM_KE15Z in the project's config.h file. The compiler needs to be set to build for Cortex m0+ (and not Cortex M4) and the linker script KE_256_32.ld should be selected [KE_256_32_BM.ld for downloadable version] {the linker script extension may vary for different compilers, whereby *.ld is valid for GCC}

FRDM-KE15Z Binaries

Here are some binary files that can be loaded to the board. These were built using the µTasker applications (serial loader and V1.4 application) and can be simply generated using the supported compilers/IDEs [these were built using GCC], built using different configuration options or modified to suit specific requirements or hardware derived from this board :

  • uTaskerSerialBoot_FRDM-KE15Z_SREC-IHEX_UART.bin UART loader [8.2k] allowing applications to be loaded at link address 0x8000 by sending either SREC or iHEX files. When operating, the green LED blinks at 5Hz. To force the loader reset the board with SW2 held down. To disable the watchdog, reset the board with SW3 held down. This can be loaded using the FRDM-KE15Z's USB-MSD boot loader.
    Note that the loader limits application sizes to 40k - it can be built without limits using the µTasker project.
  • uTaskerV1.4.12_BM_FRDM_KE15Z.SREC KE15 application with command-line menu on the virtual COM connection allowing various functions to be tested [58.4k SREC content]. Linked to 0x8000, it can be loaded via the serial loader's SREC mode. When the application is running the green LED blinks at 2.5Hz.
  • uTaskerV1.4.12_BM_FRDM_KE15Z.HEX The same KE15 application in iHex format that can be loaded via the serial loader's iHEX mode.[59.7k iHex content].
  • uTaskerV1.4.12_FRDM_KE15Z.bin The same KE15 application as stand-alone software that can be loaded using the FRDM-KE15Z's USB-MSD boot loader [22.2k].
