Install cross compilation tool chain
Clone the cross compilation toolchain
git clone https://github.com/friendlyarm/.git -b master --depth 1
//or
git clone https://gitee.com/friendlyelec/prebuilts.git -b master --depth 1
Unzip
cd prebuilts/gcc-x64
cat toolchain-4.9.3-armhf.tar.gz* | sudo tar xz -C /
After decompression, the following files are generated
Add PATH
vi ~/.bashrc
viThe operation is not explained, if you don’t understand, check the vi command summary by yourself , add the following command
export PATH=/opt/FriendlyARM/toolchain/4.9.3/bin:$PATH
export GCC_COLORS=auto
Execute it to make it effective immediately
. ~/.bashrc
Verify that the installation was successful or failed
arm-linux-gcc -v
U-Boot
U-Boot download & compile
Links are provided by the official github, the download speed is very slow.
I used the githubimport giteeprocess, the following direct cloning warehouse on it.
git clone https://gitee.com/jyu_hsy/uboot_nanopi2.git
Speed is still possible
that the project is already the default branch nanopi2-lollipop-mr1, and therefore do not need to perform git checkoutthe replacement branch, execute the following command:
make s5p4418_nanopi2_config
make CROSS_COMPILE=arm-linux-
Generate after completion u-boot.bin
U-Boot update to NanoPi M2
We need fastbootto update the running NanoPi M2board SDof theU-Boot
Can be installed by the following command fastboottools
sudo apt-get install android-tools-fastboot
Back to the Windowscreen displayed, use SecureCRTto log in toNanoPi M2
Powering on the 2sinner (reset to restart on the line), a terminal press enter into the u-bootcommand mode
In the u- bootEnter the command line fastbootto enter the fastbootmode
is turned on Ubuntu, execute the following command
fastboot flash bootloader u-boot.bin
There is a pit here, after executing the above instructions, it has been stuck waiting for device
Whether experiencing this problem, please check the virtual machine enabled USB控制器and added equipment
Recommended here it is USB1.1 控制器
if you're like me to use Oracle VM VirtualBox, do not directly add an empty value USB筛选器, so after starting the virtual machine, the mouse and keyboard all been taken over, only to restart, not a joke.
Compile Linux kernel
Prepare mkimage
Compile the kernel need to use U-Bootthe toolsmkimage
You can directly use the following instructions to install:
sudo apt-get install u-boot-tools
Before gitdown ubootactually have this tool
Use the following commands to compile and install:
cd uboot_nanopi2
make CROSS_COMPILE=arm-linux- tools
sudo mkdir -p /usr/local/sbin && sudo cp -v tools/mkimage /usr/local/sbin
After performing the above operations, it can be found /usr/local/sbinin the presence ofmkimage
Download kernel src
git clone https://github.com/friendlyarm/linux-3.4.y.git
//or
git clone https://gitee.com/ezio_zhang/linux-3.4.y.git
cd linux-3.4.y
Compile the Debian kernel
make nanopi2_linux_defconfig
touch .scmversion
make uImage
Compile a little longer, be patient, after completion of the translation can be found the path to uImagethe file
Replace the kernel
Remove SD卡with a reader to read, and add the USB device, then Ubuntuappears on the desktop bootand rootfsfile (on hand this SD卡has mirrored the official burnt, may be a bit different), we will be generated uImageto move them.
Afterword
Wiki's tutorials come to an abrupt end, but the mirroring is not over!
I found another wiki document NanoPi / zh Wiki document
We also need transplants can find Debianthe file system, and then make SD卡.
According to this tutorial is SD卡to burn NanoPiM2not start properly, it may be a non-tutorial warehouse NanoPiM2used ...
to temporarily leave the pit, finished.
