根据log你没有生成 /dev/mtd 分区, 导致没有 /dev/mtdblockX
所以根文件系统没有跑起来
晕哥，生成 /dev/mtd 分区是在 dts文件里加上partition吗？
我按照 lichee zero 教程里通过bootargs传递给内核就是上面的结果了

晕哥 说：根据log你没有生成 /dev/mtd 分区, 导致没有 /dev/mtdblockX
所以根文件系统没有跑起来
晕哥，生成 /dev/mtd 分区是在 dts文件里加上partition吗？
我按照 lichee zero 教程里通过bootargs传递给内核就是上面的结果了
我也有这样的问题，请问你解决了吗？

1. linux 开启 CONFIG_MTD_CMDLINE_PARTS
2. 或者 linux 开启 CONFIG_MTD_OF_PARTS, 设备树里面添加 parts,

您好，能麻烦你说下过程吗，谢谢啦！我才刚入门不好意思好多基础都不懂。
我使用的时zero的开发板，直接使用的 https://whycan.cn/t_682.html 里的这个《 V3s主线u-boot引导官方linux,带Qt文件系统,网卡已测试.7z》 固件都不行，下面时启动的日志！

bsp linux 3.4 对吧, 那个 flash 分区和主线可能有点不同, 好像是改代码可以实现, 添加分区代码 结构体数组.

对呀，现在使用的是TF卡，可搜什么关键字呀？ 我安装教程自己编译出来也不行，使用论坛里编译好的也不行！！

fan12398 说：晕哥 说：根据log你没有生成 /dev/mtd 分区, 导致没有 /dev/mtdblockX
所以根文件系统没有跑起来
晕哥，生成 /dev/mtd 分区是在 dts文件里加上partition吗？
我按照 lichee zero 教程里通过bootargs传递给内核就是上面的结果了我也有这样的问题，请问你解决了吗？
我使用的是16M SPI flash，主线 linux，
最终试验的结果是，参考 http://nano.lichee.pro/build_sys/build_flash.html 修改设备树dts，
然后 include/configs/sun8i.h，加入如下宏，就可以挂载上去了。注意 root=31:03。
tf卡的话 参考晕哥的这篇帖子 https://whycan.cn/t_547.html ，我照着做的，一次成功。注意dd时 of=/dev/sdb，是你自己的tf卡，别写到硬盘上去了

使用TF卡终于可以进入系统了！！
直接使用论坛的《V3s主线u-boot引导官方linux,带Qt文件系统,网卡已测试.7z》
TF卡制作时按照晕哥的 https://whycan.cn/t_547.html
全部流程做完启动系统会出现 Rebooting in 5 seconds..
原来是问题是 EXT4-fs (mmcblk0p2): ouldn't mount RDWR because of unsupported optional features (400)
原因是因为我使用的系统是 Ubuntu18.04的，在使用gparted制作ext4文件分区的时候会加入旧的内核不支持的一些东西
解决办法就是制作好分区后使用 sudo tune2fs -O ^metadata_csum /dev/sdb2 去除
下面就是自己跟着教程编译一遍BSP系统了，希望不要出现问题！
感谢大家！
