请问v3s用制作了spi flash镜像之后,启动到Waiting for root device /dev/mtdblock3停住了

spi flash型号是mx25l25635,log如下。

我发现在这句话之后,

并没有列出4个mtd分区的数据,不知道是什么原因导致的。

然后最后就卡在Waiting for root device /dev/mtdblock3了。

Re: 请问v3s用制作了spi flash镜像之后,启动到Waiting for root device /dev/mtdblock3停住了

我觉得不是这个问题,因为它已经parse出了4个mtd,并且知道用/dev/mtdblock3去启动,问题是,它在wait这个设备。。。

Re: 请问v3s用制作了spi flash镜像之后,启动到Waiting for root device /dev/mtdblock3停住了

我后来下载了4.13重编译之后,这些log就有了,但是最后还是一样的,会不会那个时候dev/mtdblock3还不存在?或者叫别的名字?

重新把 log 贴上来看看, 用 code 标签包起来

问题解决了,只要在uboot里面把/dev/mtdblock3改成31:3就行了
