This tutorial shows how to trace the Linux Kernel code (i.e. record variable values at arbitrary code locations) without having to setup regular debugging connection. This allows tracing targets that would otherwise be hard to debug (e.g. embedded devices without JTAG, desktops/laptops incompatibl...
使用的Linux系统为MANJARO,内核版本号为4.4.45,对应的LINUX_VERRSION_CODE 为263213,计算方法如下: 首先将4.4.45 转为16进制为 0x04.0x04.0x2D 然后宏 KERNEL_VERSION(0x04,0x04,0x2D)展开之后得到04042D 这个16进制的数字 最后将0x040423 转化为十进制就得到了十进制的263213 即为 LINUX_VERSION_CODE的值...
Liunx Kernel 调试 1、按照华清FS3399的使用手册指导, 建立linux系统的虚拟机,按照第三章 Linux 系统编译中的说明,获取系统的所有源代码,在虚拟机中编译全系统所有代码,或者单独编译linux kernel,编译完成,将其打包拷贝到装有CVD64软件的机器上,并按照原始编译路径建立目录(例如:作者的路径为C:homelinux k3399_linux...

Solved: I have got kernel-v5.4/v4.14 version code of the Murata WIFI BT Modeule(CYW43012) driver, But I can not merge v5.4/v4.14 version driver code
