Programming TMS320C8 MVP

Hi Dan,
I don't recall any Code Composer Studio version supporting C8x. I think you mean Code Composer v2 (without the "Studio") which predates the "Code Composer Studio"line. From what I recall, that version required a little HW dongle to be attached to the PC for Code Composer to run. Does this ring a bell? Do you have this HW dongle?

Thanks

Hi Ki,

Thank you for your quick reply.

I cannot say there was ever a dongle and it would most likely be long if it did exist. I have the JTAG 3/5V Programmer that was originally used to load the TMS320C80 MVP DSP. The JTAG 25-pin end to the PC is serialized with the number "2617698-0001 (C)". Could the connector contain the software key?

Anyway, let me then reframe the question: Can this programmer still be supported to load the C8x? Currently, I have no software for this JTAG device. Or is there another, more up to date, JTAG tool on that will support loading the C8x?

yes, likely the old TI XDS510 ISA emulator. This is not the HW dongle I am referring to.

No, that is the S/N of the emulator. It is not the software key for Code Composer

The JTAG emulator can be used. But as you mentioned, you need software. I am looking at our old archives and I don't see support for C8x in Code Composer 4. That is the oldest version we have archived. I wonder if Code Composer 2 is that last version to support it. Unfortunately we don't have that version in our archives. I'll see if we have a copy of it hidden somewhere.

Ki,

If you could find a hidden copy, I would be much indebted.

Thanks.

Dan,

We have been polling as many old-timers as we can and have not found anything for you yet.

What leads you to believe the program was built with CCS v2.x, regardless of whether you mean Code Composer Studio or the earlier Code Composer?

I understand you have found some help from Spectrum Digital. How is that progressing with them?

Hi RandyP,

To answer the first question:

I am uncertain about the CCS version.  I have a backup of two ISO imagines from the original programmers: one is called C8X_SW_TOOLKIT_PC_2.00 and the other is TMC320C8X_Emulator_1.13. However, when expanded and installed onto the Windows NT machine, and I hit EMURST, the error is "NO DRIVER FOUND FOR EMULATOR."  My first problem I would guess is finding the software that installs the driver to the XDS510 ISA card.  I believe once communication is established we should be fine.  I do have a procedure for doing this but again we are rebuilding the load system with Windows NT, the XDS510 ISA, and the JTAG 3/5V programmer.

Second, I do have the Spectrum Digital XDS510 USB, but it does not support the C8X.  I have contacted Spectrum Support, but because of the rare obsolesced pedigree, they never built direct support for the C8X.   Unfortunately, I tried it anyway using Generic setup. Anyway, the board's DSP did get wiped, but the object never loaded. 

Thanks.

Rafael,

We went through the Installation procedure one more time.  We found that the setup.exe for the emulator wasn't installing the driver in the system32 directory.  In the Appendix section is how to manually setup the driver.  Once we did that, everything worked per procedure.  

Thanks.

Dan

Dan,

Thanks for reporting back your findings. Hopefully you will be able to move forward with the development environment now.

Rafael
