Queue problem using struct

Kernel
1

Im studying queue and Im with this problem. I created a method queueBoardSend() in file Utils.cpp/Utils.h and I call this method by tasks in Main.cpp. But this problem occurred:

[0;32mI (300) cpu_start: Starting scheduler on PRO CPU.e[0m
[0;32mI (0) cpu_start: Starting scheduler on APP CPU.e[0m
1 abort() was called at PC 0x40080f12 on core 0

Rebooting…

My code:

<Utils.h>
struct QueueItem
{
int Cmd, Param1, Param2 = 0;
};

void queueBoardSend();

<Utils.cpp>
void queueBoardSend()
{
if (boardQueue != NULL)
{
struct QueueItem x;
x.Cmd = 1;
x.Param1 = 2;
x.Param2 = 3;
xQueueSend(boardQueue, &x, portMAX_DELAY);
}
}

If I was to rephrase your post as “I tried to use a queue and it crashed, please help me identify why?” would I be correct?

If so, then I’m afraid you do not provide enough information for us to try and answer. For example.

Did you create the queue before trying to use it?
Did you check it was actually created, even if you think you did create it?
Does this happen the first time you use the queue?
What did you do to try and debug it?
As you seem to be using C++, how are you linking the C and C++ code?
Etc.

I found the problem. The problem is the memory size. When I created the task, I used stack depth 1024. When I changed to 8196 my code works.
