adb传输失败，文件系统变成只读的

[towel_roll]

之前测试还是正常的，今天SDK编译出来的就不行了，我的是nor flash的，求助大神

[awwwwa]

mount看看overlayfs挂载了吗

[towel_roll]

@awwwwa 没有挂载

[towel_roll]

@awwwwa 文件系统挂载失败导致的？这个一般是SDK里面什么配置的导致的呀，我是修改了rootfs的size大小

[awwwwa]

@towel_roll rootfs空间太大了把UDSIK都占了

[towel_roll]

@awwwwa 需要改哪些参数吗，我把rootfs压缩到原本的大小就可以了，但是我的rootfs会比预设的大一点，目前是通过修改sys_partition_nor.fex实现的，我的nor flash是32M的，是有空间的

[DAIZEBIN]

@towel_roll 你这个是啥平台，D1？使用nor介质启动？
使用nor的话，尝试下128扇区对齐，即12240->12280

[towel_roll]

@daizebin 好，我试试，是D1S 的
