Using -j`nproc`` rather than -j4 allows scaling based on the number of processors available. nproc is provided in the coreutils package.

# Build Instructions
|
|
|
|
## Linux
|
|
|
|
### 1. Getting source code and helper scripts
|
|
```bash
|
|
cd ~/
|
|
git clone https://github.com/OLIMEX/DIY-LAPTOP
|
|
cd DIY-LAPTOP/SOFTWARE/A64-TERES/
|
|
```
|
|
### 2. Setup toolchain
|
|
```bash
|
|
sudo apt install gcc-aarch64-linux-gnu
|
|
sudo apt install gcc-4.7-arm-linux-gnueabihf
|
|
sudo apt install kpartx bsdtar mtools dos2unix device-tree-compiler
|
|
```
|
|
|
|
### 3. Cross-compile sources
|
|
|
|
#### Linux
|
|
```bash
|
|
cd linux-a64
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- olimex_teres1_defconfig
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- LOCALVERSION= clean
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j`nproc` LOCALVERSION= Image
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j`nproc` LOCALVERSION= modules
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j`nproc` LOCALVERSION= modules_install INSTALL_MOD_PATH=out INSTALL_MOD_STRIP=1
|
|
```
|
|
|
|
#### Allwinner Pack Tools
|
|
```bash
|
|
cd ../
|
|
make -C sunxi-pack-tools
|
|
```
|
|
#### U-Boot
|
|
```bash
|
|
cd scripts/
|
|
./build_uboot.sh #A64-Teres
|
|
```
|
|
or
|
|
|
|
```bash
|
|
./build_uboot_a64.sh #A64-OLinuXino
|
|
```
|
|
|
|
### 4. Helper Scripts
|
|
|
|
## Ramdisk
|
|
Either make one with the steps below or download one from some other place.
|
|
Make sure the initrd is for `aarch64`.
|
|
|
|
### Get Busybox tree
|
|
```bash
|
|
cd ../
|
|
git clone --depth 1 --branch 1_24_stable --single-branch git://git.busybox.net/busybox busybox
|
|
```
|
|
|
|
### Configure and build Busybox
|
|
|
|
Build a static busybox for aarch64. Start by copying the `blobs/a64_config_busybox`
|
|
file to `.config` of your Busybox folder.
|
|
|
|
```bash
|
|
cp blobs/a64_config_busybox busybox/.config
|
|
cd busybox
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j`nproc` oldconfig
|
|
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j`nproc`
|
|
```
|
|
|
|
### Make initrd.gz
|
|
Use the `make_initrd.sh` script to create a simple initrd based on the busybox binary previously compiled.
|
|
|
|
```bash
|
|
cd ../scripts
|
|
./make_initrd.sh
|
|
```
|
|
### Create bootable image
|
|
Create kernel tarball :
|
|
```bash
|
|
./make_kernel_tarball.sh . ../linux-a64 #This will produce file named linux-a64-xx.yy.zz.tar.xz
|
|
```
|
|
|
|
Create simple image structure:
|
|
```bash
|
|
sudo ./make_simpleimage.sh teres.img 1000 ./linux-a64-3.10.104-1.tar.xz
|
|
sudo xz teres.img
|
|
```
|
|
|
|
Build a bootable image:
|
|
```bash
|
|
sudo ./build_image.sh teres.img.xz ./linux-a64-3.10.104-1.tar.xz xenial
|
|
```
|
|
|
|
If successfully completed, this command will create file named `xenial-teres-bspkernel-<date>.img`.
|
|
Use `dd` to write this image to an SD Card:
|
|
|
|
```bash
|
|
dd if=xenial-teres-bspkernel-<date>.img of=/dev/sdX bs=1M status=progress
|
|
```
|
|
|
|
Use these credentials to log in after first boot:
|
|
- User: `olimex`
|
|
- Password: `olimex`
|
|
|
|
Connection to the internet can be enabled via command-line by running:
|
|
```bash
|
|
nmtui
|
|
```
|
|
|
|
Feel free to install everything you want, e.g., a graphical desktop environment:
|
|
```bash
|
|
./platform-scripts/install_desktop.sh mate # installs mate desktop
|
|
```
