How to install Linux header for pcDuino8 Uno

There is no source of linux-headers for pcDuino8 Uno, so it not easy to compile an kernel module for pcDuino8 uno. But before several days ago, LinkSprite released kernel source for pcDuino8 Uno, now it can get the Linux headers from this kernel source.


  • pcDuino8 Uno
  • Host PC: Ubuntu 14.04(X86)

Kernel source


1. Prepare source code

Download the source code from github and create a directory called linux-headers-3.4.39 at /usr/src.

>sudo mkdir /usr/src/linux-headers-3.4.39
sudo cp ./linux-3.4 /usr/src/linux-headers-3.4.39 -r
sudo make O=/home/svn/linux-headers-3.4.39 sun8iw6p1smp_defconfig
sudo make O=/home/svn/linux-headers-3.4.39 modules_prepare

2. Create build soft link

cd /lib/modules/3.4.39
sudo ln -s /usr/src/linux-headers-3.4.39 build

3. Create Module.symvers

This file will be created when compile kernel source.

Go to your host PC Ubunt14.04(x64) and take the following steps to create Module.symvers.

3.1 Install tools

sudo apt-get install libc6:i386 libstdc++6:i386 libncurses5:i386 zlib1g:i386
sudo apt-get install gcc-arm-linux-gnueabihf
sudo apt-get install libncurses5-dev libncursesw5-dev device-tree-compiler u-boot-tools

3.2 Install gawk3.1.6

tar -xvf gawk-3.1.6.tar.bz2
cd gawk-3.1.6
sudo make install

3.3 Build kernel

./ config
    Welcome to mkscript setup progress
All available chips:
    0. sun6i
    1. sun8iw6p1
    2. sun9iw1p1
Choice: 1
All available platforms:
    0. android
    1. dragonboard
    2. linux
Choice: 2
not set business, to use default!
using kernel 'linux-3.4':
All available boards:
    0. eagle-p1
    1. eagle-p1-secure
    2. eagle-tvd-perf3
    3. pcduino8
    4. pcduino8-linux
Choice: 4

The Module.symvers will be created at linux-3.4 directory, and copy it to /usr/src/linux-headers-3.4.39 on pcDuino8 Uno.

4. Test

  • Create a hello.c file.
#include <linux/init.h>
#include <linux/module.h>

static int pcduino_hello_init(void)
    printk("Hello, pcDuino\n");
    return 0;

static void pcduino_hello_exit(void)
    printk("Bye, pcDuino\n");

  • Create Makefile
KDIR := /lib/modules/3.4.39/build  # Point to Linux Kernel Headers
PWD := $(shell pwd)

obj-m := hello.o

    make -C $(KDIR) M=$(PWD) modules

    rm -rf *.o .*cmd *.ko *.mod.c .tmp_versions *.symvers *order
  • Compile and test
sudo insmod hello.ko
dmesg | tail -n 1
[ 1957.116615] hello,world.
sudo rmmod hello.ko
dmesg | tail -n 1
[ 1976.438055] goodbye world

The installation of Linux headers on pcDuino8 Uno is done! Thanks to Latelan.
