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,

    Practically there should not be any limitation in programming the M29W320EB parts , irrespective of the fact whether they are manufactured by ST Micro-electronics or Numonyx.

    But since you are facing this issue only on the custom board, so in order to confirm if all connections are correct or not, I would suggest you to first try with simple code programming the sectors of the flash and check if you are able to do so.

    Without this, we cannot be sure if custom board has connectivity issues or not.

    Have you tried programming the flash using the codes given on EE-355 ?

    Kindly let me know your observation for trying the simple code on the custom board.

    Thanks,
