u-boot如何手动命令烧写到sd卡，并从sd卡启动

huawei_d

咨询下，我想从sd卡启动，然后使用命令，手动烧写到sd卡，不想使用那个自带的脚本。但是烧写后，没法启动呀，是不是和rk3399的启动有关呀

SYSTEM=${OUT}/system.img
        rm -rf ${SYSTEM}

        echo "Generate System image : ${SYSTEM} !"

        dd if=/dev/zero of=${SYSTEM}  bs=1M count=0 seek=$SIZE

        parted -s ${SYSTEM} mklabel gpt
        parted -s ${SYSTEM} unit s mkpart loader1 ${LOADER1_START} `expr ${RESERVED1_START} - 1`
        parted -s ${SYSTEM} unit s mkpart reserved1 ${RESERVED1_START} `expr ${RESERVED2_START} - 1`
        parted -s ${SYSTEM} unit s mkpart reserved2 ${RESERVED2_START} `expr ${LOADER2_START} - 1`
        parted -s ${SYSTEM} unit s mkpart loader2 ${LOADER2_START} `expr ${ATF_START} - 1`
        parted -s ${SYSTEM} unit s mkpart atf ${ATF_START} `expr ${BOOT_START} - 1`
        parted -s ${SYSTEM} unit s mkpart boot ${BOOT_START} `expr ${ROOTFS_START} - 1`
        parted -s ${SYSTEM} set 6 boot on
        parted -s ${SYSTEM} unit s mkpart root ${ROOTFS_START} 100%

        # burn u-boot
        if [ "$CHIP" == "rk3288" ]  || [ "$CHIP" == "rk3036" ]; then
                dd if=${OUT}/u-boot/u-boot.out of=${SYSTEM} seek=${LOADER1_START}  conv=notrunc
        elif [ "$CHIP" == "rk3399" ]; then
                dd if=${LOCALPATH}/rkbin/rk33/RK3399MiniLoaderAll_V1.05.bin of=${SYSTEM} seek=${LOADER1_START}  conv=notrunc

                dd if=${OUT}/u-boot/uboot.img of=${SYSTEM} seek=${LOADER2_START}  conv=notrunc
                dd if=${OUT}/u-boot/trust.img of=${SYSTEM} seek=${ATF_START}  conv=notrunc
        elif [ "$CHIP" == "rk3328" ]; then
                dd if=${LOCALPATH}/rkbin/rk33/RK3328MiniLoaderAll_V1.05.bin of=${SYSTEM} seek=${LOADER1_START}  conv=notrunc

                dd if=${OUT}/u-boot/uboot.img of=${SYSTEM} seek=${LOADER2_START}  conv=notrunc
                dd if=${OUT}/u-boot/trust.img of=${SYSTEM} seek=${ATF_START}  conv=notrunc
        fi

        # burn boot image
        if [ ! -e ${OUT}/boot.img ] ; then
                echo -e "\e[31m CAN'T FIND BOOT IMAGE \e[0m"
                exit
        fi
        dd if=${OUT}/boot.img of=${SYSTEM} conv=notrunc seek=${BOOT_START}

        # burn rootfs image
        if [ ! -e ${ROOTFS_PATH} ] ; then
                echo -e "\e[31m CAN'T FIND ROOTFS IMAGE \e[0m"
                exit
        fi
        dd if=${ROOTFS_PATH} of=${SYSTEM} seek=${ROOTFS_START}
}
通过这种方式来烧写的sd卡，


loaderimage --pack --uboot ./u-boot-dtb.bin uboot.img

        cd ../
        $TOOLPATH/trust_merger $TOOLPATH/RK3399TRUST.ini
        cd ${LOCALPATH}/u-boot

        cp  uboot.img ${OUT}/u-boot/
        mv  ../trust.img ${OUT}/u-boot/

通过这种方式来制作的uboot

这个过程有什么问题吗？有没有人指导一下呀

解决了吗？
把emmc给擦了后。 怎么从sd启动？
