Error 0x20000024/-1135 after runing a project in ezdsp2812

Hi

I have a EzDsp 2812 and Emulator XDS510PLUS and i istalled CCS v3.3.

I builded a project in c, and i loaded in the dsp. but after runing i saw this message in CCS:

Error: Error 0x20000024/-1135 Severe Error during: Register, Execution,  Unrecoverable emulation error  Sequence ID: 16 Error Code: -1135 Error Class: 0x20000024.


Can you idetifiy this probelm, and it is a hardware erreur or just problem in configuration?

Thanks.

    It is a generic emulation error so you would need to do some troubleshooting to figure out if it is a hardware issue or software issue.

    I would suggest trying to first connect and download a simple example program provided by TI (there are many examples included in the Header files and Peripheral examples package), as these are known good examples.

    Does you target connection work consistently? If it does not, the issue is probably at a lower level than CCS. The manufacturer of your emulator should have some diagnostic tools you can use to troubleshoot low level JTAG connection issues (for example, if you are using a Spectrum Digital emulator, try the SDConfig tool). If SDConfig reports errors then you need to look into hardware issues, either in the target board or emulator.

    Hi

    Thanks for your respond.

    I tried the "Example_281xEvPwm.c"  , but there is a problem in the output pwm : (there is 12 pwm outputs)  and when i measure it with an oscilloscope, the pwm2,pwm4,pwm6 show 2 V and 1.3 V and 2.1 V, and there no voltage in the other of pwm. i think that the output should be 0V or 3.3V. 

    Also, this example works a little of time and after the same erreur shown. 

    I sure now that there a hardware problem in the pwm outputs; i tried to replace pwm with a digital outputs GPIOA 13-15. i used a sofware interruption of the three compare registers of EVA.

    Firstly, this technic works good, but when i tried to declare a variables, it begin to make the same erreur.

    Can you search for the code of this erreur, i need to know where is the problem exactly? for example if this problem is of memory i will try to do not use this damaged memory in my program....etc

    Thanks Mr

    The error message itself is generic, and there could be different factors that trigger the error, so it is not easy to identify one specific cause. You could search the forums for posts with similar error to see what other users have experienced and tried to get around it. If you haave access to another target board and/or emulator that would be a quick way to isolate if the issue is tied to this specific board/emulator.
