Dear all,
I have a weird problem with my Kinetis board. I use k64 configuration files from here: https://community.freescale.com/servlet/JiveServlet/download/409196-1-276040/scripts.zip
with OpenOCD 0.9.0. I start it on the console as follows:
openocd -f interface/ftdi/olimex-arm-usb-ocd-h.cfg -f interface/ftdi/olimex-arm-jtag-swd.cfg -f target/k60.cfg -c "init; reset halt" and get back:

So far so good and I don's see anything ugly here. Then I start my gdb and print "target remote localhost:3333", what ends in bunch of errors.
Info : accepting 'gdb' connection on tcp/3333
Error: MCU is unsupported
Error: auto_probe failed
Error: Connect failed. Consider setting up a gdb-attach event for the target to prepare target for GDB connect, or use 'gdb_memory_map disable'.
Error: attempted 'gdb' connection rejected
I don't want to believe, that this generic Cortex-M4 MCU is not supported. Or am I doing something very wrong?
Thank you!
Not supported by what? (You should post on a relevant place. So far as you put, the JTAG device works.)
I suggest you try gdb or oocd places...

Hey,
The command line seems proper. Your GDB approach also.
Did you try with the default script for the target in the OpenOCD? There is a script k60.cfg in "...\scripts\target".
I also recommend you to test with a newer build of OpenOCD. You can get such from Freddie Chopin's web site (OpenOCD dev section).
Finally, if the problem persists it might be a better idea to check and post in the OpenOCD mail list - the chances for solution are higher there.
Best regards,
Lub/OLIMEX
Thank you for support. Since I am not proficient with writing configuration scripts I'll go for some other SWD/JTAG tool.
Why not ask on Oocd ML (mailing list)? Post -d3 output log.
There are people who use Kinetis stuff there.
