Hello,
I'm using Eclipse with cygwin.
I have an app with a Timer 0 FIQ and a UART0 IRQ. The timer 0 is used to
simulate a PWM. In the UART ISR I have implemented a echo. I also have a
print(char *str) function. The problem is that the only way which the
program runs is declaring a string like that:
char str[100];
str[0]='q';
str[0]='w';
str[0]='e';
str[0]='r';
...
Print(str);
If I do this, everything works fine. But if I try to initialize the
string like this:
str = "qwert"
all interrups don't work anymore.
I have tried declaring:
const char *str;
const char *str = "qwerty";
Print("qwerty");
const char *str = {'q','w','e','r','t','y'};
...
and the conclusion I have at this moment is that if I use in my code the
character "" to indicate a string, it doesn't work.
Do you have any suggestion?
Thatk you very much.

In what way does it not work - fails to compile or runtime failure? Describe the failure mode. Post the build log if it fails to build; post complete example code rather than fragments in either case. Make sure that you build with -Wall -Werror, compiler options, and clear up any warnings. Perhaps use of literal string constant where a constant is invalid? Hard to tell from your post. Clifford
