ECC hardFault on SRAM3 starting from empty project (stm32u585vit6)

[Sped]

I'm getting an hard fault when trying to start ECC on SRAM3 with a very simple project doing just ECC enabling. I tried clearing the SRAM before calling HAL_RAMCFG_StartECC or by using HAL_RAMCFG_Erase, but the result is exactly the same. Here attached the sample project I use. Any suggestion or code examples on how to solve this issue?

Hello @Sped and welcome to the community;

 

I recommend you to look at the Injecting and handling ECC errors in STM32H7 RAM - STMicroelectronics Community may help you.

Also, I think this article How to debug a HardFault on an Arm® Cortex®-M STM32 can help you to debug the HardFault. 

 

I hope this help you.

Thank you.
