Hi fellas,
I've created a sample c++ project - with lwip+freeRTOS - for two threads. It works fine as shown below:
When I tried to add 3rd thread - the build was successful - yet the none of the threads are being scheduled.
To be very specific, the 3rd task creation itself failed. Hence, I think scheduler is not even called. Why it happens so?
The threads are as follows,
void delay(){
volatile static int i,j;
for (i=0;i<10000;i++)
for (j=0;j<10000;j++);
}
void ledOn(void){
GPIO_WritePinOutput(GPIO1,9,0);
PRINTF("LED turned on\r\n");
}
void ledOFF(void){
GPIO_WritePinOutput(GPIO1,9,1);
PRINTF("LED turned off\r\n");
}
static void BLINKY(void * arg){
while(1){
ledOn();
delay();
ledOFF();
delay();
taskYIELD();
}
}
static void SERIALL(void * arg){
while(1){
PRINTF("inside Serial loop");
delay();
PRINTF(".");
delay();
PRINTF(".\r\n");
taskYIELD();
}
}
static void testIoT(void * arg){
while(1){
PRINTF("inside iot loop");
delay();
PRINTF(".");
delay();
PRINTF(".\r\n");
taskYIELD();
}
}
