CCS/AWR1642BOOST: AWR1642BOOST

CHORO CHUNG
Prodigy 30 points
Part Number: AWR1642BOOST
Other Parts Discussed in Thread: AWR1642

Tool/software: Code Composer Studio

In the swrr154.zip, the hardward check list mentioned for the SOP2.

In the item of  "AWR1642 EVM BOOST Signal  usage", the code is the "PMIC_CLKOUT" but not "AWR_MODE_SOP_2".

Per my understanding,

AWR1642 EVM BOOST Signal  usage = TI reference code base

Customer inputSignal usage = We need to self to modify code

Could you please clarify ?

** I mean if we need to self modify the TI reference code then can have SOP2 function which is for Flash programming.

Thanks

    Hello Choro Chung,
    The same pin on the AWR1642 device is used as PMIC CLKOUT and also as SOP2 signal. During the bootup time this pin is used as a SOP2 signal and the device senses this pin to decided the bootup mode (along with SOP1 and SOP0 pins).
    In order to run your own code you need to flash the binary to the serial flash using the flash mode (SOP2=1 , SOP1=0 , SOP0=1) and then booting the device in functional mode (SOP2=0 , SOP1=0 , SOP0=1).

    Regards,
    Vivek
