STM32 Nucleo 767ZI FreeRTOS benchmark

[Alex2968]

Im currently porting a CPU performance benchmark from ESP32 to STM32 that uses FreeRTOS. Im unable to make it work due to some errors that continue appearing that might suggest there is a stack overflow, but increasing the stack size doesn´t help.

Debugger console error:

set *(int *)0xE000EDFC=*(int *)0xE000EDFC|0x7F0

set *(unsigned int *)0xe0042008&=~0x1800

The project is composed of main.c, dhrystone.c and whetstone.c. I have added the FreeRTOSconfig.h file.

Now the benchmark codes whetstone.c and dhrystone.c initialiced as tasks. Both codes return information as such:

xTaskNotifyGive( taskHandle );
vTaskDelete( NULL );

Do you really expect someone to wade through four posts of unformatted source code?

If you want an answer from one of the community volunteers, you should firstly insert the code with the </> button and secondly minimise the description of the problem. Otherwise, your call for help will slowly sink into the mass of daily requests like in a bog.

Thank you for your advice.

[Pavel A.]

Does this code indeed work on esp32?

In lines 26, 27 the RTOS is not running yet so you are not in context of any thread. What do you expect xTaskGetCurrentTaskHandle() to return?

Line 43: something is missing. Does it compile at all?

Here you can find helping hands for your project.
