Hi, I am trying to boot Linux on my development board and it stucks somewhere, -- I do not see log in prompt on my Hyper Terminal. I am new to embedded Linux stuff, and not sure how to debug this.
In standalone mode, I usually start GDB to trace the software and see on which code is the problem, but how should I do for Linux? I was told briefly that Linux turns on MMU in the very early stage which makes it very difficault to debug kernel. How true is it?
I wonder if there are very good book/tutorial about Linux debug in this booting phase? I checked out "Building Embedded Linux", it mentions some linux debug using GDB, but not in details and seems only for application.
Any suggestion is higjly appreciated.
Thanks.
