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.

  • Hi Satya,

    Debugging the flash programmer code for your custom board will be little tricky.

    I tried to replicate the issue by copying the flash programmer code and changing the PLLM value to 8 and generating the DXE file for it. Then using the same in Flash programmer utility to program the flash , and I can see that driver loads successfully for the EZ-Kit board.

    Thus, I would suggest you to try able to write and read the FLASH Device using a simple C code first for debugging purpose. This will ensure that all the connection on the custom board is correct and enable you to have a better understanding in terms of FLASH devices programming.

    While programming the FLASH device you will come across Flash commands , Device ID and Manufacture ID etc., which are used in the Flash Driver code. You can also refer to Application Note EE-355, which provides a C-code for programming the flash devices. The link for it is given below:

    You can use this as a reference to write or own C code.

    Hope this helps.

    Thanks,
