CCLK for ADSP-21489 is not manipulated as per PMCTL config in my target board.

Dear Sir,

Please provide me guidance on the above subject, I tried to evaluate the target board with small application code. It is working fine as per application requirement when I port in evaluation board for ADSP-21489. But the same thing is not working on target board. The reason what I found during preliminary check is its not generating the CCLK as per requirement.

please suggest any additional check up to do and guide to sort this problem.

regards

  • Hi Satya,

    The Flash programmer .dxe is available in the following directory:

    …\Program Files (x86)\Analog Devices\VisualDSP 5.0\214xx\Examples\ADSP-21489 EZ-Board\Flash Programmer

    As you can see in the ‘readme.txt’ file, these dxe’s can be used for 0.1 and later versions of the silicon.

    As far as your issue is concerned I would request you to kindly elaborate on the steps that you have done to load the loader file in to the flash. What kind of load errors do you get ?

    Apart from this I would also suggest you to go through the Application Note EE-355, which  provides a simple and modular C code for interfacing both serial and parallel Flash devices to different SHARC processors. The link for the Application note is given below:

    Please let us know more details so that we can assist you better with the issue.

    Thanks,
