- OpenOCD config files for Kinetis
- ================================
- http://nemuisan.blog.bai.ne.jp/?eid=192848#OPENOCD
-
- These are needed for debug and programing bootloader with SWD. 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, 5V from top.
- Note that RESET is also needed to get full control with OpenOCD.
-
- --------
