Re: [OpenOCD-devel] How to program Kinetis with OpenOCD on windows?

[Thomas V. <to...@on...>]

Hi Paul,

Did a bit of digging and found a tutorial that was somewhat relevant. So here are some basic questions that are bit more specific:

1) With the Kinetis MK20DX256VLH7, do I need the 220-470 ohm resistor on the TDI line to use SWD?
2) What should the configuration file look like, here is my attempt at an openocd.cfg:

	interface ftdi
	transport select swd
	adapter_khz 1000
	ftdi_vid_pid 0x15BA 0x0003
	ftdi_layout_init 0x0018 0x05fb
	ftdi_layout_signal SWD_EN -data 0
	ftdi_layout_signal nSRST -data 0x0010

I did notice there was a kinetis_256K.cfg, should I be using that instead, if so how?

If anyone has a working cfg file they are willing to share, that would be great!
3) Installed WinUSB driver for the Olimex ARM-USB-OCD, is this the best options?
4) When I try run "openocd.exe" in the directory with the openocd.cfg I get this:
	
	Open On-Chip Debugger 0.10.0 (2017-08-21) [https://github.com/sysprogs/openocd]
	Licensed under GNU GPL v2
	For bug reports, read
	        http://openocd.org/doc/doxygen/bugs.html
	Info : FTDI SWD mode enabled
	adapter speed: 1000 kHz
	Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED
	Info : clock speed 1000 kHz
	Error: BUG: current_target out of bounds

5) Based #4, where do I get libusb?  I tried changing the driver to libusb-win32 and libusbk, same error.  So I must be missing something else.

Thanks for your patience and understanding.

-Tom

Please check the README.Windows , install WinUSB driver as suggested, and OpenOCD should just work. For production programming you should be able to use "program" command.

What exactly is your question, what doesn't work?
