Hi, I found out, that the option O_DIRECT for opening a file on a fat- filesystem successfully completes. But reading and writing to that file leads to EINVAL errors (using kernel 2.6.18).
I would like to access on certain files on a flash-disk without cache usage, whereas the rest of the filesystem shall be accessed normally/cached. I am aware of the previous discussion. My application is not targetting on a pure file usage (I can live with the existing features for that), but also for a side-channel IO to interact with the device. Do you see a way to solve my problem by any workaround? Is O_DIRECT support for fat-fs feasible in future? Grateful for any response. Thanks in advance Hubi
