CCSv6.1: XDS100v2 emulator intermittent issue

Guru 19925 points

Hello I am having an XDS100v2 emulator intermittent issue on my desktop computer.  The issue doesn't seem to happen on my laptop.

A test return the information given below.  I ran xds100serial from the command line (i.e. C:\ti\ccsv6.1\ccsv6\ccs_base\common\uscif>xds100serial).  It returned the results shown below.

What could be causing the issue?

Stephen 

UPDATE2:

After conecting to the target, the xds100serial application indicates there are no XDS100 emulators on the system even though it seems like the target is connected, i.e. I can run and stop and then run the target. 

C:\ti\ccsv6.1\ccsv6\ccs_base\common\uscif>xds100serial
Scanning for XDS100 emulators...

No XDS100 emulators were found on the system.

UPDATE1:

Restarting code composer fix the problem until it happens again a short time later.  I seem to remember there was an emulator update not too long ago.  Could that be causing the issue.

After restarting Code composer:

XDS100v2 test

[Start: Texas Instruments XDS100v2 USB Debug Probe]

Execute the command:

%ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

[Result]

-----[Print the reset-command software log-file]-----------------------------

This utility has selected a 100- or 510-class product.
This utility will load the adapter 'jioserdesusb.dll'.

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 '-151' (0xffffff69).
The title is 'SC_ERR_FTDI_OPEN'.

The explanation is:
One of the FTDI driver functions used during
the connect returned bad status or an error.
The cause may be one or more of: invalid XDS100 serial number,
blank XDS100 EEPROM, missing FTDI drivers, faulty USB cable.
Use the xds100serial command-line utility in the 'common/uscif'
folder to verify the XDS100 can be located.

  • Hi Steven,

    Do you feel there's some issue with your desktop USB port? Frequent disconnections can be verified by monitoring Device Manager.

  • I am using my laptop today and I don't have access to my desktop.

    I am having XDS100v2 issues on my laptop also.  It takes approximately 2 min and 45 seconds to download the code to the target device.  I had this issue a long time ago and I thought I fixed it.  At that time, I fixed the issue by changing from a USB2.0 port to a USB3.0 port.

  • Ok, I did have the XDS100v2 plugged into a USB2.0 port.  I go a little confused since I have a lot of cables plugged into my laptop. 

    It now very fast at downloading the program.

    That still doesn't solve my issue with the desktop.
