STM32F446: how to run code from externally-attached off-chip SDRAM?

[shiyming]

I am currently using the STM32F446ZET6 chip, which comes with 16MB of off-chip SDRAM. I have been trying to run the program in the SDRAM, but have not been successful. I would appreciate any help.

Hello @shiyming and welcome to the community;

I recommend you to look at How to set up the FMC peripheral to interface with the SDRAM IS42S16800F-6BLI from ISSI and follow the steps share in this article to configure your project.

Also, you you can get inspired from an available example FMC_SDRAM.  This example describes how to configure the FMC controller to access the SDRAM memory. This application has been tested with STM32446E-EVAL board and can be easily tailored to any other supported device and development board.

I hope this help you.

Thank you.
