IRAM1 vs. IRAM2

bkaz4283

Hello,

in project setup, you can chose memory addresses for IRAM1 and IRAM2, Who can explain what IRAM1 is used for vs. IRAM2? I couldn’t find it documented anywhere.

Thanks!

    Hi Brian.

    It can be that there are two internal RAMs, for example, one faster and the other slower.
    It can be that one of those RAMs can be accessed by, for example, dedicated DMA and the other can't.
    It may again be that it is just same RAM split to 2 parts for different usage by the application.

    So, that is actually just an option for the programmer to use two separate regions for any reason if needed.
