Hi Tom and the OpenOCD Team
Another progress update.
Because I am programming my Flash from absolute zero (ie no linker offset), I
am convinced that the Tcl Proc "program" is not able to write the FCF at 0x400
- 0x40f ( it requires a 32 bit double word write instead of the "program
sections" used by the "program" command.
I have created a bash script to split my binary image into 3 parts as follows :-
vect,bin 0x000 - 0x3ff
fcf,bin 0x400 - 0x40f
app.bin 0x410 - EOF
I now launch a Msys2 Terminal to erase and program the Flash as follows :-
noel@DESKTOP-0AFLL5T MSYS /w/arduino-1812/portable/sketchbook/BlinkTestBlue
$ openocd -f interface/ftdi/olimex-arm-usb-ocd.cfg -f target/kx.cfg -c
"program vect.bin erase verify 0x000000" -c "flash write_image app.bin 0x410;"
-c "flash verify_bank 0 app.bin 0x410" -c "reset run" -c "exit"

This results in a "verified OK" and a "contents match" for the app.bin part.
And I am presented with a "Bright Flashing Blue Led".
By the way the "mass_erase" sets the FCF block to default value so that it will
not get bricked.
So I leave that as is for now.
I will put together Github tutorial on this and include the "Bash Script" for
creating a nice "OpenOCD Programmer" over the next week.
A big "thank you" to all for the tremendous work in getting the better of
Kinetis.
Now How Do i close this ticket???
Best regards.
Noel Diviney.

** [tickets:#270] Kinetis MK22FX512: Error writing FCF Block 0X400 - 0x40f**
**Status:** new
**Milestone:** 0.9.0

Hi nall,
Error at address 0x400 when programming flash on Kinetis MK22F512xxx12
However, when I press the reset buuton after programming the Led Blinks
normally.
Does the FCF block have to be skipped somehow?
Is the "Error: libusb_open() failed with LIBUSB_ERROR_NOT_SUPPORTED" a problem
given that the program runs.
The terminal output is as follows :-
noel@DESKTOP-0AFLL5T MSYS /w/adgp-1611/portable/sketchbook/BlinkTestBlue/build
$ openocd -f interface/ftdi/olimex-arm-usb-ocd.cfg
-f target/kx.cfg

I am having difficulty understanding how to manage the FCF flash block.
Any help would be much appreciated.
Many Thanks Noel Diviney
