Hi,

I use recursive function qsort.

How can increase the size of the stack?

I use Cosmic compiler with Stack Long (modsl0) memory model.

Regards,

Hello,

there's no need to increase the stack size, as this is not a parameter you can control (at least directly) in your source files or application settings.

In a typical stm8 application, the stack is initialized at the highest ram address and then grows backwards: if it grows too much, one of the two things below will happen, both leading to unpredictable system behaviour (crash!):

- the stack will overwrite some other memory area (probably global variables)

- the stack pointer will wrap around to its original value (hardware limitation)

Regards,

Luca (Cosmic)

I don't know if it helps your issue, but your question has 'recursive' and 'size of the stack' - and that really helped me a lot thanks!.

Im running FreeRTOS on STM32F1 series.

I also have a recursive function. Mine has programmed limits on its depth, but it was still causing the HardFault_Handler to execute.

I fixed it by increasing the stack size on the FreeRTOS thread. In this case form 128 to 256.

osThreadDef(Handle, StartHandler, osPriorityBelowNormal, 0, 256);

I was able to make the setting the the CubeMx configuration as well.

Thanks again!
