PROSAGA码农传奇-Linux/Unix-如何为RISC-V编译Linux Kernel 4.20

<div class =“post-text”itemprop =“text”>
  <P>
    由于您使用了目标，因此可能无效
     <code>
      riscv-defconfig
    </code>
     而不是
     <code>
      defconfig
    </code>
     一 - 见克里斯斯特拉顿在评论中的暗示。
  </p>
   <pre>
    <code>
      ls -l arch/riscv/configs/
total 4
-rw-rw-r-- 1 user user 1641 Mar  5 11:59 defconfig

</code>
  </pre>
  <P>
    此后的命令集能够使用Bootlin'流行边缘'工具为riscv构建一个4.20.14内核：
