_task_ready() doesn't working on MQX Lite

Hi all !

I'm learning about MQX Lite, but it's really hard due to lack of documentation about that.

Recently, I had a problem with "task switch". Basicly, I'm running into a task_1 and this call a _task_block(); .Right after that, my task_2 (with same priority) becomes active and runs a _task_ready function to make task_1 be ready again.

But, when I call _task_ready, my microcontroller seems like have lost itself, and what I see in debug window is the firmware paused on PE_DEBUGHALT();

There is the code of two tasks:

void read_task(uint32_t task_init_data)

{

for(;;)

{

_task_block();

}

void write_task(uint32_t task_init_data)

{

for(;;)

{

_task_ready(read_task); //Try to make "read_task" ready

}

> I'm running this on FRDM - KL25Z

Can anyone help me? Thanks

The prototype is

void _task_ready (pointer td);

td is pointer to the task descriptor of the task to be made ready.

you can use

TD_STRUCT_PTR td_ptr = _task_get_id(tid);

_task_ready(td_ptr);

You can check the Freescale MQX Lite RTOS reference manual and user guide for more details.

Have a great day,
