There is also another approach, using a debugger to watch the firmware live as it runs, but I am not familliar with how to do that.
I am using Linux, I use hexl-mode in Emacs as a hex editor and objdump from the binutils-multiarch package as a disassembler, mainly because that is what I am used to using for programming, but there are probbaly lots of other tools that will do a similar job.
I mainly used sites such as ARM assembler guide guide to learn about ARM assembly language.
If you want to start a thread to ask questions about particular subjects then I'd be happy answer them as best I can. |
Thanks - I know some C#, am pretty proficient in VB - easier, than C of course. I will do some playing and if I have time to really learn I will start the thread.
