Crossconnect lite and LPC1768 issue

Hi,

Any reason that a Crossconnect lite wont connect to a LPC1768 (NGX Technolofies Blue Board).

The Lite is working fantasticaly on other boards based on LPC2368 and LPC2478, but I cant connect to this board, I get an error message of :  Read operation Failed(GetOverlappedResult).  It is possible that the board is faulty but I can communicate to it via RS232 and FlashMagic. As this is my first attempt at Cortex-M3, I am wondering if I am missing something about this new chip

I have been througth  the FAQ and this forum looking for answers and even spent hours with Google. I have tried with adaptive clocking turned on and off and have tried various values for the JTAG Clock divider all to no avail.

Any suggestions would be most gratefully received.

Regards to all Roger...

    Hi Roger,

    I am also using teh NGX board with 1768 & it works fine with Crossconnect.  It is possible that the Interface JTAG circuitry on NGX board is faulty. ie improperly soldered pull up resistors. Just try to touch up with a soldering gun. It should work.

    Hi ANUP,

    Thanks for the information. I have checked the solder joints and looked for shorts etc, but no luck so far.

    I have also Emailed NGX to let them know of the issue.

    Many thanks again,

    Roger...

    Are you using the latest version of the CrossConnect lite firmware?

    Updates can be downloaded from the CrossConnect for ARM web page.

    Hi Jon,

    Possibly not, I have not upgraded the firmware since Paul sent the Crossconnect late last year. 

    Just tried running the update and got a message saying that the attached Crossconnect is not compatable with the update.

    Have I got the correct update for the Crossconnect Lite I downloaded the Windows version from the Crosconnect page ?

    Thanks, Roger...

    Hi Again Jon,

    I just checked the firmware version currently on the Lite, it is : Version 2.2 Build: 21 September 2009.

    Cheers, Roger...

    It could be that you have an early version of the CrossConnect Lite - I believe devices with serial numbers prior to 04020000 cannot be upgraded.

    I have Serial Number 04010007.

    With that serial number and firware version, does that mean that it is incompattible with the LPC1768?

     

    Thanks, Roger...

    I haven't been able to verify it but I suspect this is the case. Certainly, CrossConnect Lite works fine with an LPC1768 with the latest firmware (v2.13).

    I'm afraid you'll need to send it back to us if you want it updated.

    Thanks Jon,

    I have Emailed Paul to discuss the options.

    I'm a linux user, how can I check the firmware version on my Crossconeect lite  (I have a crossconnect classic that works fine with the SWD adapter after I updated its firmware), but the firmware updater simply complains about "The connected CrossConnect is not supported by the Crossconnect updater" (and then my keyboard and mouse start behaving very erratically :-/ , looks like it causes some USB issues) . But is doesn't seem to tell me anything about current or available firmware versions anywhere....

    Peter,

    Unfortunately the "CrossConnect is not supported by CrossConnect Update" message indicates that you have one of the early versions of the CrossConnect Lite that could not have its firmware updated and therefore cannot be updated by the CrossConnect updater application. This also means that it does not support SWD.

    If you have a JTAG target you can connect to, the firmware version information is visible in the CrossStudio target properties window when connected.
