several consecutive "printf" lines causes infinite loops

good day everybody!

im having a bit of a problem with coding in CCS Studio DSK 2.12

i have several "printf" lines in my code and it causes infinite loops
in execution. i usually tend to have many consecutive "printf" lines
as a way of debugging (in order to see the values of my variables in
specific parts of my program.

my code is as simple as this:

include
void main(){
//some intializations here

printf("RESULT 1 = %d \n", X1);
.
.
.
printf("RESULT 10 = %d \n", X10);

//some code here

}

but CCS only outputs lines until RESULT7 and goes on with the infinite
loop even though there's no instructions in the program to repeat.

im thinking its some sort of a bug in the stdio.h header file but i'm
not really sure.

any ideas?

big thanks!

Try using LOG_printf() instead. printf() places a heavy strain on the JTAG interface
between DSP target and host CCS software. Some of the newer DSK cards, like 6713 and
5510, have a turtle slow JTAG bitrate, and enough printf() will shut them down
depending on what other DSP code is running.
