   5 These are needed for SWD debug and programing bootloader. To flash keyboard firmware use 'dfu-util'.

   7 Flash security of Freescale kinetis
   8 -----------------------------------
   9 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.

  12 Example
  13 -------
  14 Debug:
  15     $ openocd -s tool -f tool/openocd.cfg
  16     $ arm-none-eabi-gdb build/infinity.elf -ex "target remote localhost:3333"
  17
  18 Flash bootloader:
  19     $ openocd -s tool -f tool/openocd.cfg -c "mt_flash kiibohd_bootloader.bin"

  22 Infinity SWD pinout
  23 -------------------
  24 SWD pins are placed next to reset button; SWD_CLK, SWD_DIO, GND, VCC from top.
  25 Note that RESET is also needed to get full control with OpenOCD.
