Port the C program in the host to the arm Development Board.

Write programs on the host. What if Makefile is not written?

The method is to use gcc, because it is transplanted to the arm Development Board, so the arm-linux-gcc is used.

The following is a summary of the Methods:

1. decompress the cross-compiling file of arm-linux-gcc to a directory, such as/usr/local/arm, to generate a directory such as 4.4.1.

2. Set the environment variable # sudo gedit/etc/environment, add the path:/usr/local/arm/4.4.1/bin, and make it take effect # source/etc/environment

3. Go to the c file directory, find the file such as led. c, and run the command # arm-linux-gcc-o led. c

4. Place the generated led file on the Development Board and add the executable permission. # sudo chmod 777 led

5. Run the program./led

This is a complete process.
