STM32F0 Audio device HardFault_Handler(); error problem.

[MWask.1]

Hi,

I am currently trying to develop the Audio device on STM32F0 to stream audio data from USB to IS2 signal, although It worked without any issues on STM32F4 discovery board, when I am trying to apply same logic for Nucleo32 It does not seem to work at all. Windows displays the board like so:

I will try to describe my problem in more details; after successful compilation, while debugging, program stops on HardFault_Handler(); . Code part that seems to be error cause is in usbd_audio.c file in Middlewares section of the project.

I tried to add more heap memory to solve this issue but changing it in the project does not seem to affect STM32F042K6TX_FLASH.ld and when I change it manually it gives an compilation error.

 

The code is generated through STM32CubeMX, I have not done anything to it. Still I will attach them if someone would like to look through it.

Am I on good track? Did anyone had that issue before? Please share your thoughts.

Part claims to have 6KB of RAM, and you're accessing ~15KB deep into it.

You're buffer can't be 15360 bytes deep.

Can't have a 15KB buffer in a 6KB part, reevaluate

That's right, this MCU have no enough RAM.

Oh thank you all for your time. Problem has been resolved.

Hi @Imen DAHMEN​ ,

This uC can not be used as Audio device. The reason is not enough RAM as @Community member​  and @prain​  stated. To resolve the problem I switched to different STM32 with enough memory for the task.
