Error connecting to the target on DM6467T DVEVM

Other Parts Discussed in Thread: OMAPL138

Hi,

I am trying to connect to an DM6467T DVEVM with an XDS100v2 emulator. After starting CCS v4.1.1.00014  I click "debug" and I get :

"Error connecting to the target:
Error 0x80000260/-1137
Fatal Error during: Execution, Initialization, OCS,

It appears that the target is being held in reset.  This may be
due to Wait-In-Reset (WIR) configuration set by the EMU0=0
and EMU1=1 pin settings.  If this is the case, DISCONNECT
all CONNECTED devices including icepick and then select
RETRY to clear the WIR configuration.

If this is a multi-core system, the master CPU may not be
releasing the DSP/MCU from reset.  Please check your
configuration in CC_setup and/or your GEL file to ensure that
nothing is blocking the DSP/MCU from being released from reset"

CCS Version: v4.1.1.00014

Host Operating System:Windows 7 pro 64 bits

Gel files: I use the gel files given  with the board

Target connector used 14 pin TI JTAG

Emulator model: XDS100v2

 

I'd like to connect only to DSP side in a first time to test my code.

1. How can i get through this error and connect to the  DSP only?

2. Do I have to connect first to the ARM to release the DSP from reset as I read somewhere?

3.Can I connect to the ARM with CCSV4 and an 14pin TI to  pin ARM adapter on XDS100v2 to achieve that?

4.In Target Configuration, do I have to bypass some cpu (Arm968 for example) and select the DSP as slave ?

Thanks,

CC

    CC,

    The option 2) is the recommended one. The ARM holds the DSP in reset and a GEL script file can release it.

    I don't have a Davinci HD here with me to report the exact details, but the procedure to accomplish this is very similar to the one reported in the post below:

    Hope this helps,

    Raphael,

    I am still trying to connect to the DSP side of an DM6467T DVEVM with an XDS100v2 emulator. After  having changed the JTAG clock frequency, I could go through the initialization but I had this message in the console window :

    "ARM926: GEL Output:  DaVinci HD1080p ARM Startup Sequence

    But now I can't connect anymore (sometime it's possible). It seems to be the same problem as on the OMAPL138.

    http://e2e.ti.com/support/arm174_microprocessors/omap_applications_processors/f/42/t/39607.aspx?PageIndex=1

    Is it a problem with the emulator driver as my OS is Windows 7 pro 64 bits ?

    Which file "Invalid file format" is refering to ?


    CCS Version: v4.1.1.00014

    Host Operating System:Windows 7 pro 64 bits

    Gel files: I use the gel files given  with the board

    Target connector used: 14 pin TI JTAG/ 20 pin ARM JTAG

    Emulator model: XDS100v2

     

    Thanks,
