RVD ICE CM3 ROM Table

Note: This was originally posted on 16th June 2010 at http://forums.arm.com

Hi,

I am trying to work with a CM3 implemented in Xilinx FPGA and I am trying to connect it through RVD ICE.
I do not want to connect it through CoreSight Modules as the my CM3 core does not have it.

But I want to connect to CM3 ROM table directly, or else I want to add CM3 as a device manually but in the Add device Menu I see the Cortex Tab in the registered devices disabled.

Can anybody suggest any solution ...?

    Hi there,
    Not sure what you mean by "my CM3 core does not have it (CoreSight Modules)".
    The Cortex-M3 design included the SWJ-DP and ROM table, so unless it has been removed by the designer, you should be able to access it easily.
    I would suggest you to contact ARM support team so that we can understand what system design configuration you are using and see what can be done to resolve the problem.

    Hi Joseph,

    Thanks for your reply I have contacted ARM Support now.

    What I ment was in a normal scenario after connecting JTAG and you have ARMCS-DP visible in the JTAG chain, the next step is to read the CoreSight ROM table. I was getting error for that, after digging in the subject I had a doubt like the ROM table inside the CM3 is not the CoreSight one and it is its own CM3 ROM table.The CoreSight DAP component may not support that.
    Thanks
