7020EMMC启动

根据引用，在启动Zynq7020芯片的EMMC存储器时，需要将拨码开关拨到emmc启动对应的设置。具体而言，需要将SW8拨到1000_0000，将SW9拨到0000_0000。这样设置后，芯片将从EMMC分区加载引导。根据引用，还可以通过修改代码中的"mmcinfo"为"mmc dev ${sdbootdev}"，来进一步配置SD和EMMC设备。关于在Linux环境下挂载EMMC、进行EMMC分区、格式化和文件使用测试的详细步骤，请参考引用中提供的相关信息。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
