I compiled hello world on the reference design.

Added   -f kinetis.cfg  in the option to let opensda server use this config file

but i am still  getting this error:

Open On-Chip Debugger 0.8.0-dev (2015-01-09-16:22)

For bug reports, read

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:

at file "embedded:startup.tcl", line 58

in procedure 'interface' called at file "C:/Freescale/KDS_v3/openocd/bin/..//scripts/kinetis.cfg", line 3


I read some where that it is related to bad firmware. i want to use the on chip opensda  in the kw40z reference design

just for burning new firmware every time, speed is not important.


i could not find any solution to this error.

is this bug can be solved?  or we must buy jlink to burn firmware?
