Change the execution of a program ——————— Once you use GDB to hang the debugger, and when the program is running, you can dynamically change the current debugger's running circuit or its variable value in GDB based on your own debugging ideas, a powerful feature that allows you to better debug your program, for example, You can walk through all the branches of th

Recently picked up u-boot to tune, although said before the transplant, debugging success, but that bitter ah, GDB's cursor jump to jump, and the variable can not be traced, only by guessing, or using the serial port output. Consider that it should be compiled with the use of optimization options, so long as the GCC optimization options are removed, or choose not to optimize, you c

Overview of GDB commands———————Once GDB is started, you can start debugging with GDB's commands, as soon as you are brought into GDB's debug environment, and GDB commands can be viewed using the Help command, as shown below: /home/hchen>

Label:In general, GDB is mainly debugging the C + + program. To debug C + + programs, first at compile time, we have toAdd debugging information to the executable file. This can be done using the-g parameter of the compiler (cc/gcc/g++). Such as:> cc-g hello.c-o Hello> g++-G hello.cpp-o HelloWithout-G, you will not see the program's function name, variable name,
