Debugging w/IRQ's enabled on TMX320C5515 eZdsp USB Stick

John Westmoreland43

Hello All,

Wanted to ask a question - when running the debugger with interrupts enabled, it seems to be a little unstable.  I have tried this in 'real-time' mode as well but the results seem to be the same.

I think also the usbstk lib supplied by Spectrum Digital isn't reentrant - could be the cause of some of this, maybe not,  but thought I'd mention it.

Has anyone else using the TMX320C5515 on the eZdsp USB stick experienced this?

Thanks,
johnw

    John,

    What exactly do you mean by unstable operation? Does it lose connection entirely, the code jumps to the middle of nowhere, CCS freezes momentarily...? I haven't experienced this myself, but it is surely interesting to investigate. If you have an example project we could use to test it, that would be even better.

    I suggest also asking this in the C5000 forum, since people there may have a better understanding on the usbstk lib code and (maybe) workarounds to the behaviour you are experiencing.

    Cheers,

    Rafael
