    Information about Patches and RAM use

    ToCa_3568211

      With the 20719 we notice that only, roughly, 1800 bytes of the 16KB AON is available for our use.

       

      The comments in make_cortex-m4_gcc.mk mention that AON is being utilized by patches; in addition to the 64KB already taken from main RAM for use by Patches.

       

      If there a map that shows memory that comes available when certain patches are not loaded?

       

      I expect that since we are not using WIFI, for example, none of the wifi patches would be loaded, and that should free up some memory in main "Patch" RAM or AON.

       

      Another note mentions that Pairing information may be written to AON memory.  Is that operation taking from the 1800 bytes "available" or is some amount reserved in the 14+K already taken by the system?
