Jorijn van der Graaf 738148b51a All checks were successful image / image (push) Successful in 2h13m32s Details camera: enable the FP6 main camera stack (kernel config) milos-linux combined-stable now carries the camera-main merge (af49850e65bd): camss C-PHY support, the IMX896 main sensor, the DW9784 AF controller and the board DTS for all three (the VL53L3 ToF node is DTS-only for now, its driver is future work). Kernel config gains CONFIG_VIDEO_IMX896=m + CONFIG_VIDEO_DW9784=m - the camss core, CAMCC and CCI are on since the ultra-wide commit, and the libcamera side (IMX896 tuning, contrast AF, AWB stabilization) already ships since aport r8.

fp6-img

Flashable postmarketOS images for the Fairphone 6, built nightly from the Catcrafts milos-linux combined-stable kernel branch, with imsd (userspace VoLTE) preinstalled.

Maintained by Jorijn van der Graaf (TheMightyCat) at Catcrafts.

Caution

Emergency calling is unverified. Calls (including 112/911) go through imsd, whose emergency path is spec-shaped but has never been verified against a live network.

What works

Everything on the combined-stable branch: display, touch, wifi, cellular data, NFC (reader), speaker audio, microphone, IMU, magnetometer, barometer, ambient light/proximity — plus VoLTE calls (both directions) through imsd.

Verified on exactly one device / one carrier (KPN NL). Reports from other carriers are very welcome.

Flashing

Download fp6-img.tar.xz from the latest release and unlock the bootloader (Fairphone's official process).

Install: with the phone in fastboot mode,

tar xf fp6-img.tar.xz
cd fp6-img
./install.sh

install.sh erases dtbo, flashes the rootfs, RAM-boots the kernel, writes the boot partition from inside Linux where the bootloader's NV-wipe cannot see it, then reads the modem NV back and reports the result. The bootloader never writes boot.

Default login: user / 147147 (same as official postmarketOS images — change it). Never re-lock the bootloader with a custom image installed.

VoLTE configuration

imsd is installed but needs your carrier's P-CSCF address:

# /etc/imsd.env
PCSCF=<your carrier's P-CSCF IPv6 address>

Find it in a stock-firmware capture or your carrier's IMS documentation, then systemctl restart imsd (the service is enabled at boot and waits for this file to exist). See the imsd README for the full variable reference and carrier assumptions.

How it builds

build.sh drives pmbootstrap with the aports/ overlay in this repository:

device/linux-postmarketos-qcom-milos — the pmaports kernel aport, repointed at combined-stable with the exact kernel config the development FP6 runs.
modem/imsd — imsd, packaged from source. Its provides=81voltd keeps the conflicting modem-firmware IMS helper off the image (two IMS stacks cannot share one PDN).
main/postmarketos-config-nftables — adds the -imsd subpackage accepting imsd's IPsec-protected SIP ports on the IMS PDN (auto-installed alongside imsd).
device/catcrafts-fp6-repo — subscribes the installed system to the Catcrafts apk registry (signing key + /etc/apk/repositories entry). CI publishes every built package there, so apk upgrade delivers kernel/imsd/GNSS updates between image releases.
