DM8168 using CCS to access internal and DDR memory

Graeme Parker

Hi

This should be a real simple question. We've just started to bring up our own DM8168 board. So far I have been able to connect to the CortexA8 using CCSv4, and I can single step whatever it does after reset. I can see the internal registers, but I want to be able to access internal memory which I believe is at 0x40300000. Are there any GEL files available that I need to set the processor up to allow this? Currently I just get a CCS message saying "Unable to access device memory..."

Thanks.

    Hi,

    This memory region may be protected or some other device configuration may be preventing access to this region. If this is the case, usually a suitable GEL file allows full access to the device memory.

    You can test the GEL file available at this page.

    Hope this helps,

    Rafael

    Thanks. Yes, I found a GEL file.

    The important point about this file is that all of the "clever" stuff (setting up loads of registers, PLL, etc) takes place when you CONNECT to the device. If you are already connected then there is no script available to make this initialization - unless I modify the GEL.

    But it works now, so I'm happy.
