/Partition_Info添加如下配置进去
Part Sel0 PartitionNameabc FlashTypeemmc FileSystemnone Start262M Length4M SelectFile/这行代码指定了以下内容
Sel0表示这是一个选定的分区即被选中用于后续的操作。PartitionNameabc表示分区的名称为“smdt”即这个分区被命名为“abc”。FlashTypeemmc表示这个分区所在的存储介质类型是 eMMC。FileSystemnone表示这个分区还没有被格式化为任何文件系统类型。Start2148M表示这个分区在存储介质上的起始位置是 2148MB。Length4M表示这个分区的长度是 4MB。
