# Building a Mobian Image for the Pixel 3a
|
||||
|
||||
## Prerequisites
|
||||
|
||||
Cloning the repositories
|
||||
|
||||
Kernel: https://salsa.debian.org/erebion/sdm-670-linux
|
||||
|
||||
Mobian Recipes does not have the changes merged, as the kernel is not yet part of Mobian: https://salsa.debian.org/Mobian-team/mobian-recipes/-/merge_requests/113
|
||||
|
||||
Take my temporary fork of Mobian Recipes instead, for now: https://salsa.debian.org/erebion/mobian-recipes/-/tree/erebion/sargo-build?ref_type=heads
|
||||
|
||||
The fork will be maintained until there are official Mobian images for the Pixel 3a.
|
||||
|
||||
## Compiling the Kernel
|
||||
|
||||
First `cd` to the kernel repo.
|
||||
|
||||
Then:
|
||||
|
||||
```bash
|
||||
gbp pq import # import the patches to a patch-queue branch with the patches applied
|
||||
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make defconfig sdm845.config sdm670.config usb-gadget.config # make kernel config, usb-gadget ist required for SSH via USB Cable
|
||||
ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- make -j$(nproc) bindeb-pkg # make Kernel deb (one directory level up)
|
||||
```
|
||||
|
||||
## Building the Image
|
||||
|
||||
First `cd` to the Mobian repo.
|
||||
|
||||
Copy the kernel deb to `devices/qcom/packages`, so that it gets installed onta the image we are about to build.
|
||||
|
||||
Temporary workarounds:
|
||||
|
||||
- Comment `loupe` in `include/packages-phosh.yaml` as that is currently not available in the repo. The image viewer can be installed later.
|
||||
- Comment `mobian-phosh` because of a broken dependency and insert `phosh-core`, the metapackage just installs things like an XMPP client and nothing important we couldn't install later.
|
||||
- Add your SSH authorized keys file to `overlays/ssh/authorized_keys`, important so you can log in later
|
||||
|
||||
```bash
|
||||
./build.sh -t qcom -s -u mobian | tee mobian-build.log # -s for SSH, which we need later
|
||||
```
|
||||
|
||||
(If you replace `mobian` with your own username, you will have to use that one for SSH later, of course)
|
||||
|
||||
Wait. It takes a while. Make sure the internet connection is stable, as the build fails if it cannot download all packages successfully.
|
||||
|
||||
Note: Your SSH Host Keys currently get generated while building the image, please don't give your image to anyone else.
|
||||
|
||||
## Flash to device:
|
||||
|
||||
```
|
||||
fastboot --set-active --slot a
|
||||
fastboot flash boot_a mobian-qcom-phosh-20240614.boot-bonito-sdc.img
|
||||
fastboot flash userdata mobian-qcom-phosh-20240614.rootfs.img
|
||||
fastboot erase dtbo
|
||||
```
|
||||
|
||||
Boot up the device. Connect it via USB.
|
||||
|
||||

# sargo-temp
|
||||
|
||||
Temporary fixes that make Mobian work on sargo
|
||||
Temporary fixes that make Mobian work on sargo.
|
||||
|
||||
Please note that the MIT license does not apply to `qcom-firmware`.
|
||||
|
||||
## What to do
|
||||
|
||||
### Build Image
|
||||
|
||||
Instructions can be found in IMAGE.md in this repo.
|
||||
|
||||
### Flash image
|
||||
|
||||
First flash the image. Boot the phone.
|
||||
|
||||
Connect via SSH: `ssh mobian@10.66.0.1`
|
||||
|
||||
Accept the host key.
|
||||
|
||||
### Roll out workarounds using Ansible
|
||||
|
||||
You have to have `ansible-playbook` installed.
|
||||
|
||||
Go to the Ansible folder: `cd ansible`
|
||||
|
||||
Roll out workarounds: `./workarounds.sh`
|
||||
|
||||
Reboot phone via SSH.
|
||||
|
||||
Connect to wifi.
|
||||
|
||||
Rolling out the workarounds for audio requires installing packages from the repo, so we need an internet connection.
|
||||
|
||||
Roll out audio workarounds: `./audio.sh`
|
||||
|
||||
## Project Status
|
||||
|
||||
### This Works
|
||||
|
||||
- booting
|
||||
- display
|
||||
- touch
|
||||
- modem
|
||||
- plymouth
|
||||
- battery/charging
|
||||
- mobile data
|
||||
- wifi
|
||||
- torch
|
||||
- suspend
|
||||
- SMS (only receiving was tested, but I don’t have reason to believe sending wouldn’t work)
|
||||
- vibration (udev rule needs to be added to the corresponding package)
|
||||
- audio (ALSA config not packaged, but can be manually added using the playbook in this repo)
|
||||
- Bluetooth™ (mac address currently has to be set manually after each boot, udev rule in this repo does not look right yet)
|
||||
- eSIM (supported, but needs a bit more testing)
|
||||
- camera (front camera buggy, back camera works but patches not in git yet)
|
||||
- GPS (needs some improvements to accuracy)
|
||||
|
||||
### This Does Not Work (Soon)
|
||||
|
||||
- USB host mode
|
||||
- call audio (requires packaging q6voiced to get audio from the modem, but of course VoIP would already work)
|
||||
- full disk encryption (no installer images yet, once the other stuff is done this will magically be there)
|
||||
|
||||
### This Has An Unknown Status
|
||||
|
||||
- Fingerprint Sensor
|
||||
- NFC (no idea what software I could use for testing, but should work, does so on pmOS)
|
||||
|
||||
### This Is Missing And Will Come Later
|
||||
|
||||
- accelerometer
|
||||
- magnetometer
|
||||
- ambient light sensor
|
||||
- barometer
|
||||
|
||||
### The Main Issues That Prevail
|
||||
|
||||
- A systemd unit with a hard-coded value, that has to be manually edited for now (`droid-juicer.service`)
|
||||
- ALSA config not yet packaged, has to be manually copied for now
|
||||
- few things to do for kernel packaging and then submitting that to Mobian
|
||||
- no call audio yet, as the daemon (q6voiced) is not yet packaged, but can be manually added for now using the playbook in this repo
|
||||
- simple script that brings up Bluetooth has to be added somewhere
|
||||
|
||||
### The Sources (Use The Source, Luke)
|
||||
|
||||
- My efforts of packaging a device-specific kernel: https://salsa.debian.org/erebion/sdm-670-linux (which will be used until all patches are part of upstream Linux and we can finally use a regular mainline kernel)
|
||||
- `mobian-recipes`, which is used to build images: https://salsa.debian.org/Mobian-team/mobian-recipes
|
||||
- `droid-juicer`, which retrieves some important files from some partitions: https://gitlab.com/mobian1/droid-juicer
|
||||
- https://wiki.postmarketos.org (lovely folks, thanks for sharing everything you found out the hard way :D)
|
||||
|
||||
### Thanks For All The Fish
|
||||
|
||||
Huge thanks to be sdm670-linux project and flamingradian who runs the project (just one person!) to make sure the Kernel works on those devices! :)
|
||||
|
||||
I don’t know how Kernel development works, so I would have never started porting without this project.
