Я просто использовал стандартный пример по запуску программы hello_world от NXP:
cat mimxrt1024_evk.conf  
# Use the ROM bootloader to load the image to RAM
CONFIG_NXP_FLEXSPI_ROM_RAMLOADER=y
# Generate HEX file to confirm addresses written to flash
CONFIG_BUILD_OUTPUT_HEX=y


cat 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)>;
       };
};
