					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.
