ezDSP Digital spectrum board heating issue

Other Parts Discussed in Thread: TMS320F28335

I am using ezDSP TMS320F28335 for my project. I am trying to PIL simulation for 4000 seconds with matlab. When I tried this my processor got locked at 72 sec and I also observed board PS767D301 IC and processor both heated up. May I know the reason for this issue. Is ezDSP is not designed for longer continuous usage.

Some information about my application

My application uses ROM - 111250 Bytes and  RAM - 14804 Bytes.

My matlab model has 1ms, 2ms, 10ms and 100ms sub-systems.

I am not interfacing any external hardware, but using SCI to pass the inputs.

    Hi,

    The ezDSP is designed for debug purpose at SATP.  We are not aware of any issues with the board that cause the board to heat up to a very high temperature.

    This doesn't seem like a software issue to me.  Instead, this seems like a hardware/power/jumper issue.

    Perhaps ESD damage occurred to the chip?  I might also recommend that you make sure that the C2000 chip's pins are held within the absolute maximum ratings.


    Thank you,
    Brett
