*Hello* Paul Fertser
whit respect to my first question.
Yes, you are correct, I'm using newlib librdimon to do semihosting, but I
guess that something is wrong since when I test the system() function the
return value indicates that there is not any command processor
(shell(LINUX) or the command line(WINDOWS)) available therefore I've
concluded that there is some issue on that implementation.
The return value of *system*() is one of the following:
* If *command* is NULL, then a nonzero value if a shell is available,
or 0 if no shell is available.
do you have some info about my other questions.
2) if I need to start from scratch I want to know If someone had
implemented something on this topic.
3) otherwise which could be the starting point in order to include
such functionality as fast as possible.
4) I'll appreciate any other recommendation.
