TMS320C6748 code download issue

Other Parts Discussed in Thread: TMS320C6748

Hello forum:

I have a new design with a TI TMS320C6748 on it and now that I’m trying to bring the board up and download code to run on the DSP, I can only get CCS to download code to it after a power up. Once I try to load code again (after the first time) the data validation fails.  I have tried enabling the various resets in the configuration, but no success with that approach.  I am assuming that there is something wrong with my design, but I’m not sure where to look.

I am using:

* CCS 6.1.2
* Linux on my host
* XDS560v2 via LAN

I'm loading code through the JTAG into mDDR memory.

I also found that if I load the code after power up, it works.  If I then recompile, while the target is still running, CCS will ask if I want to reload. If I say yes, it doesn't have a problem. Everything works great. If I stop the debugging session and try to reload, that's where the problem exists.  Perhaps it's my gel file?

Any feedback or input is welcomed and appreciated!

Thanks again!

Paul

    Dear Paul,
    Its recommended to reset the board if you want to reload the code again.

    What error you are getting ?
