An attempt to access the named emulator via USCIF ECOM has failed

Other Parts Discussed in Thread: DM3730, OMAP3530

Hi,

I am using XDS200 to try to debug  DM3730 with  Torpedo™ SOM. I am connecting the emulator to the SOM by using a logicpd adapter and Iget the following error:

[Start]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -r -o -S pathlength -S integrity

[Result]

E_RPCENV_IO_ERROR(-6) No connection: DTC_IO_Open::dtc_io
Failed to open i/o connection (xds2xxu:0)

An error occurred while soft opening the controller.

-----[An error has occurred and this utility has aborted]--------------------

This error is generated by TI's USCIF driver or utilities.

The value is '-250' (0xffffff06).
The title is 'SC_ERR_ECOM_EMUNAME'.

The explanation is:
An attempt to access the named emulator via USCIF ECOM has failed.

[End]

I am working on windows 7 and using ccs5.3.

I checked my drivers and this is my versions:

xds2xx Emulator CDC serial port (COM7)

xds2xx User CDC serial port (COM8)

Ihave gone over some of the questions in the form and still havn't found notting...

    Hi,

    This error may stem from the fact the XDS200 is either not being properly recognized by Windows or CCS cannot communicate with the XDS200 due to some other reason.

    The usual issues are reported at section 6 of the page below:
    processors.wiki.ti.com/.../XDS200

    Just as a sanity check, I tested the XDS200 and it worked fine with the DM3730's sister device OMAP3530 (BeagleBoard original). However, I am using a much newer release of both CCS (5.5) and TI Emulators component (5.1.636.0).

    Therefore, given you seem to be using a very old version of CCS (v5.3), it is possible there is a bug or inconsistency that was fixed throughout the years. The simple update of the TI Emulators component may be a solution (details at section 7 of the page above), but it is only tested in CCSv5.5. Using it with 5.3 may work or not.

    Hope this helps,
    Rafael

    the problem is solved. as it seems the problem was loose connection of my adapter.
