Tool/software:

Hi,

We are using

SDK : mcu_plus_sdk_am64x_09_02_00_50

Processor : AM6421

CCS : 12.7.1

When we try to analyze the R5F1_0 stack usage of Freertos tasks in CCS with stack usage tool, we observe some tasks use 100% of stack allocated.

When we try to increase the stack size for that particular task, there is no change in the stack status, and it also disturbs the stack usage of other tasks.

Suggest how the configure the stack sizes in CCS for Freertos.

We are running the application from DDR.

Hello Narasimha Rao,

While creating the Task, we will give the stack size.

Please confirm how you are allocating the stack size for a particular Task.

Regards,

Anil.

Hi Anil,

Thanks you for the reply.

Yes we are defining the stack size using stack size parameter while using xTaskCreateStatic call.

Even we increase the stack size the stack usage tool in CCS shows 100% usage.and other task status changes.

Hello Narasimha Rao,

Please use the API below to print the stack usage of all tasks in your system.

The Stack usage window will give information about the statistically allocated memory, like code and data memory.

char Buf[200U];
vTaskList(Buf);
DebugP_log("%s\n", Buf);

Regards,

Anil.
