buildroot怎么只编译根文件系统呢? 大佬们请告知下
离线
入坑太浅,编译了好多次,都是错误

同求编译方法。

你的 bootargs 是什么?这个是和根文件系统系统有关的错误
Target Architecture (ARM (little endian)) --->
Target Binary Format (ELF) --->
Target Architecture Variant (cortex-A7) --->
Target ABI (EABIhf) --->
Floating point strategy (VFPv4) --->
ARM instruction set (ARM) --->
新手请教,你指的是这个吗?

你把linux启动的log贴全吧
刚我重新编译了下buildroot,错误就成这个了。
