    It sounds like the input clock is not properly connected to the device.

    Please check the input clock to the DSP. Also, check XCLKOUT pin to ensure device is not in limp mode. SYSCLKOUT frequency in limp mode could be from 1 - 5 MHz.

    There was a bug... I posted this picture and my question, and only the picture is sent...

    Actually, I have a problem with Piccolo F28027. I tried to adjust crystal oscilator and the processor has gone in limp mode...

    CCS 3.3 displayed message from the picture attached in my previous post... So, this message is present whenever I try to flash a program on processor F28027...

    I tried to flash a program on another F28027 and It works OK...

    Do you know how to solve this problem?

    Regards

    Nikola.
