Официальный пример от NXP для работы приложения hello_world только в SDRAM:

mimxrt1024_evk.conf:
# Use the ROM bootloader to load the image to RAM
CONFIG_NXP_FLEXSPI_ROM_RAMLOADER=y

mimxrt1024_evk.overlay:
/delete-node/ &sdram0;
/ {
        chosen {
                zephyr,flash = &sdram_code;
                zephyr,sram = &sdram_data;
        };

        /* Divide SDRAM into two partitions for Code and Data */
        /* Micron MT48LC16M16A2B4-6AIT:G */
        sdram_code: memory@80000000 {
                device_type = "memory";
                reg = <0x80000000 DT_SIZE_M(16)>;
        };
        sdram_data: memory@81000000 {
                device_type = "memory";
                reg = <0x81000000 DT_SIZE_M(16)>;
        };
};

Kconfig:
if NXP_FLEXSPI_ROM_RAMLOADER

# Adjust LMA when zephyr,flash is in SDRAM
