Precautions for driver makefile

I recently studied qq2440 and want to perform pose detection for underwater robots. It is very troublesome to use Linux to program device drivers, it is good to find an example on the Internet. copy it for backup.

On PC:

1. OBJ-M: = Hello. o
2. Kerneldir: =/lib/modules/$ (shell uname-R)/build
3. Default:
4. Make-C $ (kerneldir) M = $ (shell PWD) Modules
5. Install:
6. Insmod hello. Ko
7. Uninstall:
8. Rmmod hello. Ko
9. Clean:
10. Make-C $ (kerneldir) M = $ (shell PWD) clean

On arm:

1. OBJ-M: = Hello. o
2. Kerneldir: =/opt/friendlyarmqq2440/ghcodes/kernel-2.6.13 # Corresponds to the kernel directory of your own Development Board
3. Default:
4. Make-C $ (kerneldir) M = $ (shell PWD) Modules
5. Install:
6. Insmod hello. Ko # www.linuxidc.com
7. Uninstall:
8. Rmmod hello. Ko
9. Clean:
10. Make-C $ (kerneldir) M = $ (shell PWD) clean

The difference is only in the kernel directory.
