OpenOCD config files for Kinetis
================================
http://nemuisan.blog.bai.ne.jp/?eid=192848#OPENOCD
These are needed for SWD debug and programing bootloader. To flash keyboard firmware use 'dfu-util'.
Flash security of Freescale kinetis
-----------------------------------
If FSEC of flash config is changed accidentally SWD/JTAG you can't get debug access until doing 'mdm mass_erase' with JTAG, CMSIS-DAP or OpenSAD adapter. HLA(high level adapter) like stlink doesn't work for this.
Example
-------
Debug:
$ openocd -s tool -f tool/openocd.cfg
$ arm-none-eabi-gdb build/infinity.elf -ex "target remote localhost:3333"
Flash bootloader:
$ openocd -s tool -f tool/openocd.cfg -c "mt_flash kiibohd_bootloader.bin"
Infinity SWD pinout
-------------------
SWD pins are placed next to reset button; SWD_CLK, SWD_DIO, GND, VCC from top.
Note that RESET is also needed to get full control with OpenOCD.
