    No, LPCXpresso is not supported.

    See http://rowley.zendesk.com/entries/41301-which-jtag-adapters-are-supported-by-crossworks for a list of target interfaces supported by CrossWorks.

    Thanks Jon.

    No worries .. i'll just go straight to a real prototype with a jtag interface.

    Having just acquired one of these things myself, I am wondering if I can snap off the LCP-Link (toss it) and connect to a crossconnect.  That is, does the crossconnect support NXP's Single Wire Debug protocol or is that planned?  Otherwise, I suppose I could flywire connect to the appropriate JTAG lines as all of these signals are brought out to a pins.  Labled AD0-AD4, P0.10 on the LPCXpresso.  I am assuming the SWCLK is the same as TCLK.

    The Code Red thing works ok but it sure isn't Crossworks!

    I'm looking into the LPC11xx for a new product. Kelly, did you manage to get the LPCXpresso running with CrossWorks?

     

    Kind regards,

    Ben

    Ben, I haven't gotten back to playing with it as my free time is limited.  Anyway, I am guessing it is no big deal as the JLink supports the SWD and crossworks supports the JLink.  So, if you snap off the programmer and make up a transition to the JLink...

    The LPCXpresso JTAG link is not open.  Despite a number of times around the block with NXP on this one, we have not come to a resolution of the issue.  I'm not sure we ever will, we've had two face-to-face meetings and two years on it.  Just believe it's not going to happen.

    The CrossConnect Classic and CrossConnect Lite now support SWD with a free firmware upgrade and a paid-for small adapter:

    Thanks Kelly, Paul, for the info. I have some old JLinks too, but they don't support SWD. I'll go look at the SWD adapter then.

     

    Kind regards,

    Ben

    Hi Paul,

     

    My prototype went on hold but is due to come alive again in a day or two, so does...

    Mean that the jtag on LPC111x does not work with CrossWorks, or are you talking specifically about their SWD interface?

     

    Thanks,

    Gordon.

    The LPC1100 is fully supported in CrossWorks V2 along with SWD using our adapters or FTDI-based adapters.

    We do not support the LPCXpresso JTAG adapter, that is all.  I do not believe we're ever going to come to a resolution of the issue at hand.

    OK, so it's their usb-based doggle bit that's not supported, not the jtag on the chip itself. Good.

    Thanks again,

     G.

    That is correct.  If you want to wire up a connector for the LPC1100 snap-off board, then that would be supported, but better to purchase something like this:
