Hello,
I have a problem with threads. All of them are of same priority, with osDelay(300), except the uartThread which has osDelay(1). Everything else is the same for all threads. I have allocated 20k of HEAP and in ioc file it says im using only 3.5k so that should be fine i guess. However, only one of the threads is running (I2C_temp works fine besides the uartDATA), others never even enter the for(;;) loop. Any ideas?
So this is the freertos.c file where I create the tasks

Solved! Go to Solution.

So i found the solution. Even tho I used .ioc file to change the overall HEAP size, i did not allocate more heap to the threads. When I was using sprintf() the stack overflow happened. I manually increased stack size of the threads:
