Loading symbols on Davinci DSPs - How to on DM648 EVM?

Hi

I'm used to the C55x JTAG interface where you can boot the DSP, then attach your JTAG emulator and connect without having to set the BOOTM pins to emulator boot. This was really helpful since I could load symbols later and set breakpoints.

On the DM648, the CCS can't connect to the EVM without the BOOTM bits set to emulator. Is this a feature of the EVM or is this just how Davinci's work?

Is there a way to connect the JTAG and load symbols after its booted from FLASH (for example).

Thanks

    Is there actually something in the flash for the DM648 to start executing?

    The reason I ask is that if the flash actually has contents that are valid, the DM648 will start executing this.  You should be able to connect to the running target, provided it is executing meaningful code.
    If the flash is erased, it is unlikely the DM648 is executing meaningful code and therefore may be in the weird state, although I would have thought it would take an exception.

    Hi Brandon

    If I set the EVM dip switches to boot from flash (SW2-1 off, SW2-2 off, SW2-3 on, SW2-4 off), let it run the demo program (I verified by viewing the video ouput), connect the XDS510 emulator, then in CCS do Debug->Connect, I get the following. You can see at the bottom the output states that connecting is not possible. It requests that I set the dips to all off.

    Cheers

    THE SYSTEM IS NOT IN EMULATION BOOTMODE!  GEL SETUP WILL NOT RUN!
    If you plan on loading software via the JTAG connector, you should
    disconnect, turn off the device, and set the bootmode switches to
    emulation bootmode (SW2-1, SW2-2, SW2-3, SW2-4 all OFF). Then power
    on the device and try to reconnect.

    Connecting Target... Not Possible!

    Looks like the fix is to remove any BOOTCFG related "if" statements from Lyrtech's .gel file. Now I can load symbols without having to change the EVM's dip switches.[:$]
