Board: FRDM-K22F rev A1
IDE: KDS v3.2.0
Firnware version: 0203
And I upgraded to 0221 a few minutes ago (I upgraded to 0221_k20dx128_k22f_0x8000.bin)
SDK: v2.0 for FRDM-K22F
Two weeks ago I was successfull in debugging the "Hello World" example on the FRDM-K22F using OpenOCD debugging.
Today I receive errors when trying to debbug the "Hello World" example.
Here is what OpenOCD gives:
For bug reports, read http://openocd.sourceforge.net/doc/doxygen/bugs.html
Info : only one transport option; autoselect 'cmsis-dap'
Error: unable to open CMSIS-DAP device
Error: unable to init CMSIS-DAP driver
Error: Error selecting 'cmsis-dap' as transport
Runtime Error: C:/Freescale/KDS_v3/openocd/bin/..//scripts/kinetis.cfg:3:
in procedure 'script'
at file "embedded:startup.tcl", line 58
in procedure 'interface' called at file "C:/Freescale/KDS_v3/openocd/bin/..//scripts/kinetis.cfg", line 3
And here is the error I receive from the debugger in Eclipse:
I did observe this with the original firmware version 203. Then I upgraded to version 221, but still the error is the same.
I made sure I had the "-f kinetis.cfg" in the debugger config options. Still the same error.
I tried running the openocd command line executable. Here is what happended:
It seems the device is secured.
But the only thing I did with the board was debugging the "Hello World" example two weeks ago, and then today I am ready to start development, and I am unable to run the "Hello World" example.
