/proc/kcore文件有 一个ELF格式的头(linux可执行文件的头,类似于windows可执行文件的PE头,用于标记程序中各个段的位置),因此你可以用gdb之类的调试 器直接分析它,另外要说明的是,因为有那个ELF头,所以/proc/kcore文件的大小比计算机安装的物理内存的大小略微要大一些。The whole memory can be dumped in the w...
davtest 1.0 Tests WebDAV enabled servers by uploading test executable files, and then (optionally) uploading files which allow for command execution or other actions directly on the target http://code.google.com/p/davtest/ dbd 1.50 A Netcat-clone, designed to be portable and offer strong encrypt...
8.2 The Shadow Password File: /etc/shadow 8.3 The Group File: /etc/group To record that the user avr is a member of the groups users, staff, and teach, we would see the following record in the password file: avr:x:1001:100:Anthony Robins:/home/avr:/bin/bash ...
以下是基于linux0.11的代码。 一 内核的五大结构 二 中断工作流程 1、ARM回忆 (1)做CPU工作模式的转化 (2)进行寄存器的拷贝与压栈 (3)设置中断向量表 (4)保存正常运行的函数返回值 (5)跳转到对应的中断服务函数上运行 (6)进行模式的复原及寄存器的复原 ...
To make sure that debugging is possible, the elf file needs to be executed. Also, it cannot be manipulated directly because the linking address will be relocated. For this, a few tricks should be used: The first step is to make sure that the environment is clean and that old objects ...
上述分析到cmd都会放入到.u_boot_cmd段中,所以find_cmd才可以从__u_boot_cmd_start开始,到__u_boot_cmd_end结束。 为了更加深入的理解u-boot是如何执行命令,我们自己定义一个command 可以借鉴bootm这个我们已经研究,而且将要继续研究的命令来写一个自定义的命令 思路:首先定义,然后写函数,然后要注册到数组(结...
The zip file contains the `.bin` for direct loading via u-boot and the `.elf` for loading from Linux via remoteproc. I can start the Zephyr image from u-boot using: ``` ext4load mmc 1:2 0x80000000 /lib/firmware/zephyr.philosophers.mimx8mp_evk_ddr.bindcache flush bootaux 0x80000000...
它特别讨论了动态加载的x86 ELF文件。您学习到的信息将使您了解如何在主程序(main方法 - 泽者注)启动之前调试程序中出现的问题。我告诉你的一切都是真的,但有些事情会被掩盖(有些细节不会被特别说明,因此无关紧要 - 译者注),因为它们不会让我们朝着目标前进。此外,如果您静态链接,一些细节将不同。这个我就...
