Hello ,

I have CW for ARM 2.0.5.2010.... and what to connect to my LPC1114-Board with the Olimex ARM-USB-OCD debug-tool.

I get only the message "cannot set debug register".

With the NXP LPC Xpresso debugger I can connect to my board, but the software works not good.

I have read about an adapter between the olimex and my board.

Have anyone an idea ?

Thanks for help

  The 1114 only has Single Wire Debug and not a JTAG debug port, hence, you will require an adapter for your Olimex JTAG probe:

  Paul,

  From that blog, I gathered that Crossworks already supports SWD using a J-Link.  Is that correct?

  I believe it has supported SWD on J-Link for some time, yes.
