dd if=/dev/zero of=flashimg.bin bs=1M count=16 为什么出来的文件是大于16M

无情一刀 · 2018-09-19 13:58:23

我用上面的语句生成一个空文件，大小的是16M

就会出现上面的文件大小，因为我的flash 是16M的这里生成出来是16.8M了

无情一刀 · 2018-09-19 14:32:35

晕哥说：

16777216 = 0x1000000 = 16MiB = 16.8MB
1024B = 1KiB = 1.024 KB
你按上面的算一下.

我现在是要通过jffs2去启动板子还是有点问题不知道是那一块出现了问题

晕哥说：

文件系统挂载成功了，但是 /sbin/init 不能执行, /bin/sh 也不能执行.

刚才重新换了一个文件系统重新编译后出现下面的应该是成功了你看看呗晕哥
