Hello.
I am contacting you because the situation has improved.
I have tried various things.
The situation has been improved by adding k_sleep() to the process in the thread.
There is no stack overflow and the added thread is running.

The thread source code is shown below.

--------------------------------------------------------------
static void DSP_thread(void *arg1, void *arg2, void *arg3)
{
static uint64_t exec_count = 0;
while (1)
{
if (exec_count == 0){
LOG_INF("DSP_thread Exec");
}
(*1)
++exec_count;
if (exec_count > 10000) exec_count = 0;
}
}
--------------------------------------------------------------

In (*1) above
k_sleep(K_MSEC(5));
above (*1) has improved the situation.

The cause of the stack overflow is unknown, but since it has improved, we will proceed in this state.
Thank you in advance.

Hi,

[quote user="soeta"]I have never set K_THREAD_STACK_DEFINE.
I have also searched the project and could not find anything that uses this word.[/quote]

In your initial question, there was this line - K_THREAD_STACK_DEFINE(DSP_thread_stack, 100).

Best regards,
Dejan

Hello.

I have never set K_THREAD_STACK_DEFINE.
I have also searched the project and could not find anything that uses this word.
I have set CONFIG_**** and other settings in prj.conf, but where should I set K_THREAD_STACK_DEFINE?

Thank you in advance.

Hi,

K_THREAD_STACK_DEFINE line should be outside of the function. Have you done it that way?

Best regards,
Dejan

Hello.

I ran with CONFIG_THREAD_NAME=y
but there is no change in the LOG and the name of the thread is not displayed.
However, as I mentioned in my initial question, this is caused by adding a new thread, so it is clear that adding a thread is the cause.
We believe that there is not enough OS stack to launch this thread.
Please let me know the settings to increase the OS stack.

Thank you in advance.

Hi,

As shown in your initial log, the thread that produces stack overflow is unknown. You could include following configuration option to enable printing of the thread name:

CONFIG_THREAD_NAME=y

When you know the name of the thread which produces the overflow, then you could proceed to increasing its stack size.

Best regards,
Dejan

Hello,

I am aware that there is a stack size setting shown below.
However, I do not know how to specify the stack size to be increased when adding a thread.
I assumed that CONFIG_MAIN_STACK_SIZE would be applicable and increased it, but it was not.

-----------------------------------------------------------------
#define CONFIG_MAIN_STACK_SIZE 7232
#define CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE 4096
#define CONFIG_ENCODER_STACK_SIZE 7500
#define CONFIG_AUDIO_DATAPATH_STACK_SIZE 4096
#define CONFIG_CS47L63_STACK_SIZE 700
#define CONFIG_POWER_MEAS_STACK_SIZE 1152
#define CONFIG_PRIVILEGED_STACK_SIZE 1024
#define CONFIG_BT_HCI_TX_STACK_SIZE 1024
#define CONFIG_BT_RX_STACK_SIZE 2048
#define CONFIG_MPSL_WORK_STACK_SIZE 1024
#define CONFIG_IDLE_STACK_SIZE 320
#define CONFIG_ISR_STACK_SIZE 2048
#define CONFIG_IPC_SERVICE_BACKEND_RPMSG_WQ_STACK_SIZE 1024
#define CONFIG_LOG_PROCESS_THREAD_STACK_SIZE 2048
#define CONFIG_SHELL_STACK_SIZE 1024

-----------------------------------------------------------------

Thank you in advance.

Hi,

There are many configuration options which allow you to set desired stack sizes. You could have a look at application configuration options for nrf5340 audio application.
