I think you need to give us some information on what device you are writing a driver for.

Gosh---you were here at 9:16 this morning, but did not bother replying to our questions. Perhaps you decided you did not need our help after all......

When I started programming the Zilog Z80, I learned the full Z80 technical manual by reading it twice.
When I switched to the Z8, I read the Z8 technical manual from cover to cover several times.
When I switched to 80x86 assembly language I read several books and manuals cover to cover. Several times. Plus of course the DOS manuals.
When I switched to Linux and Mocka I read several books on Modula-2 several times.

It will not be enough to read a few lines and then come up with the essence of a big circuit. You will need to study the material... REALLY study! Count on studying for monts on end before you can do anything meaningful.

i'm sorry for not repling...please excuse me.
i have started reading Building_Embedded_Linux_Systems to get idea about the drivers,

great!!--good to hear from you, and good luck.

If you think we have addressed your question, then please mark the thread solved (Thread Tools--at the top of the thread)
