Hi STM community, Currently we are developing an application with STM32F779I eval board.I am using Cube Mx and System work bench for STM32. We are facing issue with RAM.My application uses FreeRTOS, FatFS and SD Card driver and also CAN driver. Actually when we try to allocate memory using malloc() we are getting Hardfault error.This implies out memory of RAM.

 

But we thought of using SD Card as Extended RAM. But we are not sure how to implement this.

 

Can anyone help me how we can use SD Card memory as Extended RAM for resolving memory issue with RAM.

 

Or

 

Is there any other we can get rid of RAM issue?
