在zed的PS端运行spark：

（1）设置uboot为sd卡启动rootfs：

"sdboot=if mmcinfo; then " \
                        "run uenvboot; " \
                        "echo Copying Linux from SD to RAM... && " \
                        "fatload mmc 0 0x3000000 ${kernel_image} && " \
                        "fatload mmc 0 0x2A00000 ${devicetree_image} && " \
                        "bootm 0x3000000 - 0x2A00000; " \
                "fi\0" \

如果想从zImage启动，修改 include/configs/zynq_common.h 的sdboot 内容：

        "sdboot=echo (modified) Copying Linux from SD to RAM... && " \

                "mmcinfo && " \

                "fatload mmc 0 0x8000 zImage && " \

                "fatload mmc 0 0x2A00000 ${devicetree_image} && " \

                "bootz 0x8000 - 0x2A00000\0" \

（2）devicetree.dts修改启动参数：

bootargs = "console=ttyPS0,115200 root=/dev/mmcblk0p2 rw earlyprintk rootfstype=ext4 rootwait devtmpfs.mount=0";

（3）下载Uboot的rootfs镜像：
