USB Emulator does not connect at all in v4.1.1

John J Wu

I installed CCS4 about a month back to start work with a new library.

Anyways, I have no problem compiling under CCS4, but trying to get the emulator to work reliably is almost impossible. I have 2 emulators, both Spectrum Digital: XDS510USB and XDS510PP Plus. Both are version A models and both show similar problems. The USB model (at the moment) will not connect at all.

The Parallel Port version connects fine, but always throws some error trying to load the code into memory.

I’m running CCS4 Version 4.1.1.00014 and the newest SD drivers.

I’ve included the log, maybe it will give you an idea to what’s going on ….

The hardware is the same as I have been running for about 5 years, so I know that is not at fault. Also, if I switch back to CCS 2.2 I have no problems whatsoever.

In case you were wondering, I have both CCS 2.2 and CCS 4 installed on this machine. I really hope this is not a problem.

Then, I thought CCS v2.2 and V4 may interference each other on the same computer.  I’ve installed CCS4 on a clean laptop.  (4.1.0.02006) This fails pretty much the same way as other machine.

 Just upgraded to 4.1.1.00014, a little different now,  it looks like the code loads, but never gets to main. (I’ve also seen this on my other machine)

 I can only test the XDS510USB, there is no parallel port on the laptop.

Thanks!

    Hi,

    I also have CCSv2.21 and CCSv4.1.1.00014 in the same WindowsXP 32bit machine and can run both versions without a problem using either a XDS510USB or a XDS560PCI connected to a C6416DSK. For v2 I have the latest Spectrum Digital device drivers installed (check http://support.spectrumdigital.com) and I am using the stock v4 drivers.

    From the log you sent I could not necessarily pinpoint the exact source of problems, apart obviously that the debugger simply crashes without reason. However, I have some reports of constant debugger crashes that were solved by removing the target cache files:

    file <targetdb.dat> typically located at C:\Program Files\Texas Instruments\ccsv4\common\targetdb
    file <targetdb.cache> typically located at C:\Program Files\Texas Instruments\ccsv4\DebugServer\bin\win32
    cache file located in the same directory as the target configuration file (.ccxml) - typically located in the project directory in the workspace

    Although the first two files would not necessarily influence the CCSv4 installed in the laptop (unless there were leftovers from a previous installation), the third file can be a potential source of error, especially if the original project contains a damaged cache file that was copied when the project was migrated to the new installation.

    This is a suggestion that worked in the past with other installations, therefore please give it a shot and let me know the results, ok?

    Hope this helps,

    Rafael
