This NXP Freedom board is based on the K28FN2M0VMI15 which is a 150MHz device from the large-memory performance and integration family with Cortex-M4F core with FS and HW USB. This K28F device has 2M Flash and 1M SRAM and is in a 169 pin MAPBGA package, whereby the K28F is also available in 210-pin WLCSP. There is a 12MHz crystal on the board for optionally clocking the part, which also has various internal clocks too.

Full details and documentation for this board can be obtained from the NXP web site: FRDM-K28F

To configure the µTasker project for this board simply enable the define FRDM_K28F 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 K_2M_1M.ld should be selected [K_2M_1M_BM.ld for downloadable version] {the linker script extension may vary for different compilers, whereby *.ld is valid for GCC}
