Dear All:
Hi. I am following the tutorials on TinyOS Doc. And I have encountered
this problem:
source code:
* uint8_t dummyVar1 = 123;
event void Boot.booted() {
for (; dummyVar1 > 0; dummyVar1--) {
printf("%u ", dummyVar1);
printfflush();
for (j = 0; j < 100; j++) {
for (i = 0; i < 10; i++) {}
}
}
} *
here is the output of net.tinyos.tools.PrintfClient:
*Thread[Thread-1,5,main]serial@/dev/ttyUSB0:115200: resynchronising

Why is this happen? Why doesn't the for loop run to the final state?
Confused by this. And see from the tools.Listen, Why the prinfflush() does
not perform as expected? Can anyone help me? Lots of thanks.
