TDA2EXEVM: RF Board PMIC Power On Code in Processor SDK

Part Number: TDA2EXEVM

Hi,

We are looking for a piece of code in the ProcessorSDK that performs power on of the 2 PMICs on the RF board. Reason we would like to understand this is that we would like to change the power up sequence to the PMIC. Any pointer or help would be greatly appreciated.

Thanks,

    PMIC power on sequence is One Time Programmed into the PMIC, The power up sequence cannot be changed. What are you looking to do?

    Regards

    Piyali,

    I work with Khai and have a question about the programming of the LP87524 on the Cascade AWR board. We are building our version of the Cascade board. For layout reasons we need to swap which AWR chip is connected to which PMIC. But since the PMIC is OTP and will power up automatically I don't see a problem with the swap. But now I'm wondering what tools are available to program it? Is this something a vendor can do or does the TI tool set do it or are we going to have to roll our own? Also is the programming code available? If this is not the correct forum let me know.
