Do you use any buffers allocated by malloc? My guess is that malloc does allocation of DARAM and SARAM memory. In any case, memory returned by malloc should be not worse than the memory buffer explicitly statically placed to EXTMEM. _______________________________________________ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
