CCS/TMS320F2808: Connecting CCS to eZdsp TMS320F2808

Joe Chopy

Part Number: TMS320F2808

Tool/software: Code Composer Studio

I am trying to connect to Spectrum Digital eZdsp for TMS320F2808.
I am using Code Composer 9.1. on Windows 10.

I contacted SD and was told that this device contains an internal jtag and all I need to do is connect directly to the USB on my laptop.

When configuring the Device on the General Project tab I selected the Variant (280x Fixed Point and TMS320F2808).
The Connection: list only contains choices for XDS560V2 STM USB Emulator or XDSPro Emulator. When I press the Verify using either
of those choices I receive "E_RPCENV_IO_ERROR(-6) No connection: DTC_IO_OPEN::dtc_conf"
I have also tried un-checking the "Manage the project's target-configuraiton automatically"
I checked the Windows device manager and I can see the "SD USB Based Debug Tools - Spectrum Digital eZdsp28xx USB" listed so I believe the drivers are installed correctly.

Is there any info on how to correctly configure for use with this device.

Thanks.

Joe,

XDS510 class debug probes are not supported in CCSv9.0 and later. Basically the support software for them is 32bit and CCSv9 is a 64bit application. To use the eZdsp kit with CCSv9 you would need to connect a compatible external debug probe to the JTAG header on the board. The other option would be to use CCSv8.3 which is the last version to support XDS510.

Regards,

John

No, I am still unable to communicate with the board. I installed version 8.3 and tried connections type "Spectrum Digital DSK-EVM-eZdsp onboard USB Emulator" (I saw a similar post that used this type) but the Verify button will not become enabled.

I also had trouble with 8.3 regarding Resource Explorer. I get a "Connection Rejected" message. When I go to the link specified http://processors.wiki.ti.com/index.php/IIRES_Update and try the following link http://software-dl.ti.com/cs/esd/tirex/updates/tirex-3.7.0 I get a 404 error

I'm in the process of locating a XDS510 USB.

Joe,

The Spectrum Digital DSK-EVM onboard USB emulator is the correct connection to use. The verify button in the project wizard will not be active for this type of debug probe. It is only active if there is a verification/identification utility specified by the vendor.

Did you try to launch a debug session?

As far as the Resource Explorer 404 error. That is an update site to plug into the CCS update checker. You can select install new software from the Help menu and entry the url. Note that there is a type in the link you have (cs instead of ccs). http://software-dl.ti.com/cs/esd/tirex/updates/tirex-3.7.0

If you go to Install New Software on the help menu you can enter it there and get the Resource Explorer update.

Regards,

John

John,

I was able to create an example "Empty Project (main.c") and it appears to connect and run.

I can see a LED on the target blink when I step through.

Do you know of any examples or tutorials that describe how to flash this device using Code Composer?

Thanks

Joe

Joe,

Just place the code in flash by modifying your linker command file and CCS will flash it automatically when downloading the program.

John
