petalinux 无法生成自定义.ko文件

前言

在使用 petalinux 修改并生成最新的.ko驱动模块时，发现并没有生成当前时间下的最新.ko文件。如下图：

可以看到， build 目录下有相关的one-wire文件。可能是旧的文件导致make没有生成当前时间下最新的.ko文件。

一、删除旧的 build 目录

zzz@ubuntu-GCP1820-SS:xilinx$ rm build/ -rf
zzz@ubuntu-GCP1820-SS:xilinx$

二、编译内核模块

zzz@ubuntu-GCP1820-SS:xilinx$ petalinux-build -c one-wire     #only for one-wire moudule
