@符号前是分区的大小
@符号后是分区的起始地址
括号中是分区的名字
单位都是 sector（512Bytes）
比如 uboot 起始地址为 0x2000 sectors （4MB）的位置，大小为 0x2000 sectors（4M）
另外 flash 最大的 block 是 4M（0x2000 sectors），所以每个分区需要 4MB 对齐，即每个分区必须为 4MB 的整数倍。
,0x00038000@0x00038000(backup)
backup 分区前的分区为固件区 uboot、trust、misc、resource、kernel、boot、recovery 。
后续升级时不能修改分区大小
backup 分区后的分区 cache、system、metadata、baseparamer、userdata
是可以读写的，可以调整分区大小。但是修改分区大小后需要进入 recovery 系统格式化 cache

 

二.生成镜像时提示Out of space
