    Ben15615
    Hi, I am new to CCS, and am using ezDSP5505. I was able to successfully build and run the LED program, but when I open the register window (View|Registers), I only see IODIR, IODATA, Rev, and Die registers; none others exist. The contents of these 4 peripheral registers are all 0s. What's wrong...

    Arvind, I believe you are referring to the C5505 eZdsp Stick. Is this correct? If yes, then your observation is correct, the eZdsp Stick will only work with CCSv4. The reason is that our XDS100 low cost emulation technology is embedded in this board to support code development and debug. There are no...

    Hello Omkar, Thanks for the update. We do not think that the problem is related to the C5515 DSP itself. Having said that, we think that it could be because of the board layout or codec related layout issue. We will pass along this information to Spectrum Digital which is our partner for demo boards...
