Shared memory in Concerto /C28

Sabina,

Unfortunately I don't know the answer to your question - the BIOS team may have suggestions so I will move this thread to their forum.  Links to the thread will continue to work after the move.

Thank you

Lori

Sabina,

This error is indicating that interrupt #32 was flagged and enabled but it is never plugged.  Another words, seems like a bogus interrupt happened.

Because it wasn't plugged, the function Hwi_unPluggedInterrupt() is executed which raises the error that you see.

Hi Judah,

Thanks for the exaplanation.

We've found the problem now,

Thanks,Sabina

Hi Sabina,

For Hwi_unPluggedInterrupt issue, how do you solve this problem, I have encountered this problem, hoping to get your guidance.

Thanks, Roc

Hi Roc,

As I remember we get unpredictable interrupt(#32) as result of watchdog enabled.

pls try to disable wathcdog . (finf 'LPMWAKE' in Technical Reference Manual)

Thanks,Sabina

Hi Sabina,

    I had met the "Hwi_unPluggedInterrupt". the scene was:

    1. the App create 4 task,

    2. one task malloc 512*40 buffer size

    3. the program running in RAM

    4. copy most data to buffer

    5. when copy about 512*20 byte, the system will into Hwi_unPluggedInterrupt function.

     So, how did you resolve this issue, what's mean the Hwi_unPluggedInterrupt, how did I do to analyze this issue. Please help me.

      Thanks, Roc

Roc,

What unplugged interrupt number is being trapped?  And is this on the M3 or the C28?

If this happens in the middle of a memory copy… a guess is that the memory location or locations being accessed are invalid, or don’t have adequate access permissions, so maybe an exception is being generated.  Have you double checked that the memory addresses are correct?

Hi Scott,

This issue happened on C28335.

Yes, I just in check the memcpy, the memory address was correct.

Thanks, Roc

Hi Roc,

Ok, thanks, I thought you were running on Concerto. 

What is the interrupt number that is being trapped?

Scott
