> > ... read some text book etc before this to have correct context ? > This is a learning challenge -sorry, I cannot provide a magic recipe. Here is how I tackle such situations: - Start by writing down a list of your H/W knowledge "holes" and begin working it one item at a time. - Get some related documentation and start reading. - Ask questions - here is not the good place but out there you'll find lots of discussion groups related to H/W. - If possible try/exercise the function you are learning. Only sustained learning gets you good results - so invest time ! It is good to work on x86 or Mips but if you are not involved directly with the H/W interface it may be difficult to try your learning labs on it. Hope this helps. Good luck, Stephan. -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
