NXP/FreeScale Kinetis

NXP/FreeScale Kinetis K20

Used by Teensy-3.x. Architecture support (only) was added in NuttX-7.10. This support was taken from PX4 and is the work of Jakob Odersky. Support was added for the PJRC Teensy-3.1 board in NuttX-7.11. Backward compatible support for the Teensy-3.0 is included.

NXP/FreeScale Kinetis K28F

Use by Freedom-K28F. Architecture support for the Kinetis K28F along with board support for the Freedom-K28F was added in NuttX-7.15. The Freedom-K28F board is based on the Kinetis MK28FN2M0VMI15 MCU (ARM Cortex-M4 at150 MHz, 1 MB SRAM, 2 MB flash, HS and FS USB, 169 MAPBGA package). More information is available from the NXP website.

NXP/FreeScale Kinetis K40

This port uses the Freescale Kinetis KwikStik K40. Refer to the Freescale web site for further information about this board. The Kwikstik is used with the FreeScale Tower System (mostly just to provide a simple UART connection)

NXP/FreeScale Kinetis K60

This port uses the Freescale Kinetis TWR-K60N512 tower system. Refer to the Freescale web site for further information about this board. The TWR-K60N51 includes with the FreeScale Tower System which provides (among other things) a DBP UART connection.

MK60N512VLL100. Architecture support for the MK60N512VLL100 was contributed by Andrew Webster in NuttX-7.14.

NXP/FreeScale Kinetis K64

Support for the Kinetis K64 family and specifically for the NXP/Freescale Freedom K64F board was added in NuttX 7.17. Initial release includes two NSH configurations with support for on-board LEDs, buttons, and Ethernet with the on-board KSZ8081 PHY. SDHC supported has been integrated, but not verified. Refer to the NuttX board README file for further information.

MK64FN1M0VMD12. Architecture support for the _MK64FN1M0VMD12 was contributed by Maciej Skrzypek in NuttX-7.20.

NXP/Freescale Kinetis TWR-K64F120M. Support for the Freescale Kinetis TWR-K64F120M was contributed in NuttX-7.20 by Maciej Skrzypek. Refer to the Freescale web site for further information about this board. The board may be complemented by TWR-SER which includes (among other things), an RS232 and Ethernet connections. Refer to the NuttX board README file for further information.

Driver Status.

NuttX-6.8. Ethernet and SD card (SDHC) drivers also exist: The SDHC driver is partially integrated in to the NSH configuration but has some outstanding issues. Additional work remaining includes: (1) integrate th SDHC drivers, and (2) develop support for USB host and device. NOTE: Most of these remaining tasks are the same as the pending K40 tasks described above.
NuttX-7.14. The Ethernet driver became stable in NuttX-7.14 thanks to the efforts of Andrew Webster.
NuttX-7.17. Ethernet support was extended and verified on the Freedom K64F. A Kinetis USB device controller driver and PWM support was contributed by kfazz.

NXP/FreeScale Kinetis K66

Support for the Kinetis K64 family and specifically for the NXP/Freescale Freedom K66F board was contributed by David Sidrane in NuttX 7.20. Refer to the NuttX board README file for further information.
