Possibly saying something extremly stupid here, how about simply "fakewriting" 0xFF to the flash after an erase to update any caches?

do_erase_stuff(); /* While verifying, update cache */ for (address = adr; address < (adr + size); address++) { if ((verify = map->read8(map, address)) != 0xFF) { error = 1; break; } /* "Fake" write 0xFF's to the erased sector so that caches are updated * after we verified that uncached data is ok */ *(unsigned char*)CACHED(address) = 0xFF; }
