I am newcomer to this field. I would like to understand how these things work and what these file contain (and if I'm on the right path).
To explain my doubts, I will use the .hex file posted in a similar question: How can I decompile an ARM Coretex M0 .hex file to C++?
The .hex file contains the instructions that will be executed by the microcontroller, and the format used is http://www.keil.com/support/docs/1584/, am I right?
Now I've tried to extract some information from this file (just for learning): I've converted the .hex file into .bin file with hex2bin (as suggested in the first answer), then I've run the command "strings file.bin", and I've found some readable strings.
What does this mean? Why can I read only some strings and not all the data? Exactly what happen when I convert .hex file to .bin file? Is there a way to extract the code in which these strings are used?
Maybe these questions are too silly, but I hope that someone could explain what these files are, and what they represent. Any good resource will be appreciated. Thanks in advance.
