Loading Function from Flash/SD Card into SDRAM on MIMXRT1050-EVK(B)

I am trying to load a function from flash into external SDRAM and executing the function on the MIMXRT1050-EVK(B). The future application for this will be loading a .bin from the SD Card into SDRAM and jumping to it.

I modified evkbimxrt1050_freertos_hello to use external SDRAM. I tested the external SDRAM portion before I added my code of moving the function into SDRAM.

It looks like everything is going well until I copy the function into a buffer that is stored in SDRAM. When I try to execute the function, I get plenty of hard fault errors.

Let me know if anyone has any insights on this.

Hello Mike,

First, I'd like to apologize for my delayed response, we are having a big workload at the moment.

Regarding your issue, I recommend you to check our following document that explains how you can relocate a function into RAM using MCUXpresso, I believe this could be useful.

Have a great day,
Felipe
