OpenOCD config files for Kinetis
|

|

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.
