U-boot DDR init files to FreeRTOS sdk

Hello I am a student at Grand Valley State University. Me and 2 other students are trying to work with the nxp i.mx8m nano evaluation board. We are currently only using the base SDK and FreeRTOS. Currently we are trying to set up a program to allow us to directly read and write to the DDR4 memory on the board. We need to be able to test the DDR by reading and writing directly to it and while not running FreeRTOS on it. We are currently using the mscale_ddr_tool and are generating a ddr initialization .c file for u-boot. We are wondering if anyone in the communality has any experience porting this file from u-boot to the nxp sdk for the nano. Everyone on the team is very new to embedded development with nxp's tools so sorry for any ignorance on are part.

I have attacked the C files that we are generating for u-boot currently.

Thanks
