DFU bootloader:
|
||||
https://github.com/kiibohd/controller/tree/master/Bootloader
|
||||
|
||||
Program with bootloader:
|
||||
$ dfu-util -D kiibohd.dfu.bin

Pin Usage
|
||||
=========
|
||||
Key Matrix:
|
||||
Strobe(output high): PTB0 PTB1 PTB2 PTB3 PTB16 PTB17 PTC4 PTC5 PTD0
|
||||
Sense(input with pull-down): PTD1 PTD2 PTD3 PTD4 PTD5 PTD6 PTD7
|
||||
|
||||
|
||||
SWD pinout:
|
||||
SWD_CLK(PTA0) SWD_DIO(PTA3)
|
||||
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.
|
||||
|
||||
LED:
|
||||
PTA19(turns on with output high)

|
||||
mbed/targets/cmsis/TARGET_Freescale/TARGET_K20D50M/system_MK20D5.c
|
||||
Fix SystemInit: clock setup for internal clock. Inifinity has no external Xtal.
|
||||
|
||||
mbed/targets/cmsis/TARGET_Freescale/TARGET_K20D50M/cmsis_nvic.c
|
||||
Fix NVIC vector address of firmware 0x1000 instead of 0x0
|

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.
