Hi
I am using STM32F429 based board with IAR tool chain for compilation. I have tested SDRAM using test program and its working fine. Now I want to move heap, stack and all readwrite variables on SDRAM hence updated default icf file. Please find attached icf file.

I have also defined DATA_IN_ExtSDRAM in system_stm32f4xx.c 

But I get hardfault interrupt after SystemInit().

Can you please help understanding whats going wrong in this icf file.

Thanks
Sapana
