MYZR-SAMA5 Linux-3.18 RTL8188EU Development Guide
目录
Prepare source code
Download source code package
Download rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz from the network disk.
Decompress source code package
Create working directory
Here we create ~/my-demo/exclude_src directory，and work under the directory.
$ mkdir ~/my-demo/exclude_src -p
Copy source code package to working directory
Copy source code package downloaded to ~/my-demo/exclude_src .
Next step should be done in your own way.
Decompress source code package
- Enter source code directory.
$ cd ~/my-demo/exclude_src
- Decompress
$ tar xf rtl8188EUS_linux_v4.3.0.9_15178.20150907.tar.xz
Compilation module
Check configuration
Instruction：module compilation exist with two dependent relationships，cross compilation link and kernel，which need to be in the path designated.
- Validate configured file of compilation.
$ source ~/my-sama5/03_tools/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf.config
- Check path of source code in kernel.
$ ls ~/my-sama5/02_source/linux-at91-linux4sam_4.7
If there is kernel source code and in correct path then content of kernel source code directory can be found.
If result of execution of command is anormal，need to re-compife kernel with reference to《MY-SAMA5 L318 compilation manual》.
Compile
- Enter driving code directory.
$ cd rtl8188EUS_linux_v4.3.0.9_15178.20150907/
- Execute compilation command
$ make
Target file
- Check target file information
$ file *.ko
Execute file command to see module information compiled，example.
8188eu.ko: ELF 32-bit LSB relocatable, ARM, version 1 (SYSV), BuildID[sha1]=0x1a3bbb865d785effc8acfebf9e2c8faf066b3fbf, not stripped
8188eu.ko is the target file compiled
WIFI test
refer to《MY-SAMA5 Linux-3.18 test manual》
