制卡时，如果需要多分区，则启动分区应当为FAT16而非FAT32

第三步 Zynq板卡启动镜像

启动完成后使用sudo insmod xilinx-axidma.ko加载驱动到内核

使用dmesg | grep dma查看驱动是否加载成功，是否识别到ip核中的通道

正确加载驱动后再编写程序测试ip核功能是否正常

构建AXI Stream与rootfs为Ubuntu的Petalinux进行协作实例（通用版）

第一步 Vitis HLS创建IP核，并在Vivado中生成XSA

第二步 构建Petalinux

2.0 配置内核

2.1 编译驱动

2.2 构建Ubuntu根文件系统

第三步 Zynq板卡启动镜像
