24K should still be enough to have a small malloc pool and the rest of SPL, especially since it sounds like you already didn't have FAT support in there (which has required malloc for ages and is why Pantelis didn't spot this as a problem I think). How close to the limit are we today in the sunxi platforms? Thanks! -- Tom
