Tool/software:

Hi,

There was a problem modifying the hello world demo program.

In the freertos version, an extra print was added before taskcreate, and the entire program did not execute

This is my program

However, in the nortos version, an extra line of print statement can be executed normally

This is my program

Thank you for your reply.

The DebugP_log() is implemented differently for a freeRTOS and noRTOS case.

DebugP_log() uses _DebugP_logZone() API which is defined as below.

FreeRTOS - https://github.com/TexasInstruments/mcupsdk-core-k3/blob/k3_main/source/kernel/freertos/dpl/common/DebugP_freertos.c#L63

noRTOS - https://github.com/TexasInstruments/mcupsdk-core-k3/blob/k3_main/source/kernel/nortos/dpl/common/DebugP_nortos.c#L41

The FreeRTOS implementation uses Semaphore, see line 63 which I tagged, this will depend on the scheduler's tick. So without the scheduler, the application will not work. This is what you see when you add DebugP_log() before vTaskStartScheduler().

Karan
