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.
Sorry I have never heard of the bus. I have given all the help I can.
Regards ~Steve
