Xiaomi dipper PostmarketOS

0. Clone the repositories

cd ~
git clone https://github.com/evil-hero/postmarketos.git

1. Install pmbootstrap

cd ~/postmarketos
git clone --depth=1 https://gitlab.com/postmarketOS/pmbootstrap.git
mkdir -p ~/.local/bin
ln -s "$PWD/pmbootstrap/pmbootstrap.py" ~/.local/bin/pmbootstrap

2. pmbootstrap init

pmbootstrap init

3. Update config

rm -rf ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/linux-xiaomi-dipper
rm -rf ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/device-xiaomi-dipper
cp -r ~/postmarketos/linux-xiaomi-dipper ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/
cp -r ~/postmarketos/device-xiaomi-dipper ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/
cp -r ~/postmarketos/firmware-xiaomi-dipper ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/

4. Build linux

You should fix the warnings generated by kconfig yourself.

cd ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/linux-xiaomi-dipper
pmbootstrap checksum linux-xiaomi-dipper
pmbootstrap kconfig edit

Build

!!! A very important step, you need to copy this file and grant execution permission when the ~/.local/var/pmbootstrap/chroot_native/home/pmos/build/src/linux-749b0d4ab2a325e11a8aba7105a0f678a8ecf404/arch/arm64/boot/dts/qcom/sdm845-xiaomi-dipper.dtb file exists.

pmbootstrap -j8 build linux-xiaomi-dipper

Open a new terminal and execute pmbootstrap log to view the log.

5. Build device

cd ~/.local/var/pmbootstrap/cache_git/pmaports/device/testing/device-xiaomi-dipper
pmbootstrap checksum firmware-xiaomi-dipper
pmbootstrap checksum device-xiaomi-dipper
pmbootstrap build device-xiaomi-dipper

6. Install

Now you need to copy or move the sdm845-xiaomi-dipper.dtb file you saved to the ~/.local/var/pmbootstrap/chroot_rootfs_xiaomi-dipper/boot/dtbs/qcom directory. If the directory does not exist, you can execute pmbootstrap install first.

To install to the system partition of an image file:

pmbootstrap install

Fix error

pmbootstrap chroot apk fix --rootfs

Or create an Android recovery zip package:

pmbootstrap install --android-recovery-zip --recovery-install-partition=data
pmbootstrap flasher --method=adb sideload

Export

pmbootstrap export
cd $(dirname $(readlink /tmp/postmarketOS-export/pmos-*.zip))
adb sideload pmos-xiaomi-dipper.zip

7. Flash

pmbootstrap flasher flash_rootfs --partition userdata

If you have a device that works with fastboot, you can boot the kernel now without flashing it:

pmbootstrap flasher boot

Otherwise, you will need to flash the kernel to the device boot partition:

pmbootstrap flasher flash_kernel

8. Now use the USB network for ssh connection

# Get the network interface name, usually the last one.
ip a
# Activate the network interface.
sudo ip address add dev enp0s20f0u1 172.16.42.2/24
# Now start the ssh connection.
ssh [email protected]

9. Now complete your system

sudo nmcli device set wlan0 autoconnect yes

Fix time zone

# type: Asia/Shanghai
