Build our ndk development environment. This part contains a lot of online materials ~~~~ To do this, you must first sharpen the tool. The following describes how to build an integrated development environment for the eclipse SDK ndk cygwin CDT.1. Build an android Development Environment Setting up the android development environment is not a key point. I believe many people who have read this article have successfully set up the environment. Let's give a brief description here. 1) download JDK

We're not going to push anymore. . we are at 0xd91b8 and 0xd91a8 place the breakpoint to see. found that 0xd91a8 will not pass. Continue ste

there is a higher priority function to use R0, then the value of R0 pushed to the stack, and so R0 by the higher priority function after the use of the pop from the stack before the value. The stack is typically manipulated when the function is called.The command for the stack operation is push and pop, usually in pairs, and at the beginning of the function, the value in the register to be used when the function is executed is pushed into the stack, and then at the end of the function the value

is somewhat abstract, and here's an example to explain it easily:Use:Arm-inux-objdump–d u-boot > Dump_u-boot.txt Copy Codecan get dump_u-boot.txt files. The file is the executable assembly code that contains the program in U-boot,In which we can see the C language function source code, in the end corresponds to those assembly code.The following is a two-function assembly code,One is Clock_init,The other is in the same C-source file as Clock_init, and another function Copycode2ram:33D0091C:33d00

jump command). For MIPS, it is saved in a register (that is, R31). For x86, it is saved to the stack (which will say what the stack is later). After the jump, execute a piece of code, you can also jump back, because the old PC saved. This is important if there are several places where you want to jump to this code and then go back to where it was. For example, the function of a piece of code is to do something based on the values of R4 and R5 (such a

, in order to avoid all downloads, here are listed behind the development of NDK to use the package: autoconf2.1, automake1.10, Binutils, Gcc-core, gcc-g++, Gcc4-core, gcc4-g++, GDB, Pcre, Pcre-devel, gawk, make a total of 12 packages 10 and then start to choose to install these packages, point skip, turn it into a digital version format, to ensure that the bin item into a fork, and SRC is the source code, this is not necessary to choose. 11 below test the Cygwin is not already installed. Run

current Cygwin version and running state, if the status is OK, then Cygwin run normal. Then enter gcc–version,g++--version,make–version,gdb–version to test, if all print out version information and some description information, then Cygwin installation success! 3. Configure NDK Environment variables A First find the Cygwin installation directory, find a home\ b Open the Bash_profile file and add ndk=/cygdrive/ Ndk=/cygdrive/e/android-ndk-r5 Exp
