AM2432: Profinet memory footprint

Tony Tang

Part Number: AM2432

How to interpret the memory footprint in the datasheet?

#1. Are they all RAM footprint? it >2MB on-chip memory size, need external DDR?

#2. But in Industry SDK release note, ALX launch pad can support profinet demo, which has not external DDR , only internal 2MB RAM. which is right?

#3. Is memory footprint different between RT and IRT?

#4. Beside the run time RAM footprint, what size flash needed to store program?

    Hello Tony,

    The information in the datasheet is taken from the map file associated with the generated binary.

    1. True, the size exceeds the 2MB RAM, therefore we are using DDR when available (e.g. EVMs)
    2. Also true, some boards do not have DDR. In this case, we use the Flash memory in XIP mode.
    3. We don't provide different binaries for RT or IRT. We have one binary for both.
    4. Please check the size of the generated appimage file after the build (~1 MB).

    Kind regards,
    Kamil
