Well, then you have to live with bugs and incompatibilities that have been fixed in the last two years since 2.6.11 was released. > When we are cross compiling code for PXA255. all the device drivers > will remain in /dev and newer one will be in /arch/ respective > folder. May I right ? No. Device code lives in the drivers directory, the arch (arch/arm in your case) directory contains architecture specific code and shouldn't contain device drivers. > If I will change mode from blocking to non-blocking , what will be > the impact of that on application ? That reads and writes will be non-blocking (what a surprise) and that you should *really* check return codes of read() and write() cause they *will* behave different. Anyway, this is not kernel related at all, so off topic over here. It's not even Linux specific but general Unix programming practice. Again, for a complete overview, see the Stevens book I mentioned in my previous reply. Yes, the book is expensive, but *really* worth it. Erik -- They're all fools. Don't worry.
