    Hi,

    Can upsd 323X run the code (boot + code) from main flash & program the secondary flash .

    more details:

    refering to the application note AN1560,

    During IAP,8032 can boot from secondary flash & after programming & verifying the main flash,we can reclassify the main flash from data memory to code memory..

    DOUBT:

    So after all these steps can i copy the contents of main flash to secondary flash?

    & reclassify the main flash again to data space???

    copy the contents of main flash to secondary flash

    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    secondary flash is you code memory not you data, so you can copy the contents of main flash to secondary flash.

    if set the main flash to boot memory and secondary flash to data memory, you can copy the contents of main flash to secondary flash, then set the secondary flash to code memory and main flash to data memory, so after reset program would run from secondary flash.
