Thanks Steve. I will go through the sources. Can you please tell me the things I need to know about the bus to write a driver. The reason I'm asking is: we are using HSX bus and I don't know nothing about it. When I googled it, I didn't find any useful info. If you know about HSX bus, can you please tell me about it.
