hi expert:
i copy tools/boot/sbl_prebuilt/am64x-evm /sbl_sd.release.tiimage to sd card, rename it to "tiboot3.bin".
then i compile examples/empty/am64x-evm/system_nortos，i copy it to sd card and renamed it to "app", this works ok too。（figure 1）
then i compile examples/empty/am64x-evm/r5fss0-0_freertos/ti-arm-clang, i copy it to sd card and renamed it to "app", this works ok。（figure 2）
when i compile examples/empty/am64x-evm/a53ss0-0_nortos/gcc-aarch64，i copy empty.release.appimage to sd card and renamed it to "app", this does not work。（figure 3）
how can i run a53 example from sd card?
