Am 19.05. um 19:30 Uhr ist es wieder so weit: #GoeLinuxOnMobile-Treffen im Strandhaus in #Göttingen/#Weende.

Wie auch beim letzten Termin werde ich #Mobiltelefon​e mit #Linux zum Ausprobieren mitbringen.

Mitunter ein #Shift6mq aus Falkenberg, auf dem sowohl #Android/#ShiftOS als auch alternativ #Linux gestartet werden kann.

🚀 Big milestone for the SHIFT 6MQ!

Just got it running through dockstation with:
✔️ keyboard
✔️ mouse
✔️ ethernet
✔️ ...DisplayPort output 🎉

Full external display support is now working, thanks to some hands-on implementation and a few extra patches on top of sdm845 Linux.

Plug it in, and you’ve got a proper desktop experience.

Running: https://codeberg.org/sdm845/linux + few custom patches which I'll try to finish today.

Got the camera working — then gave it focus. Always focus 😉

SHIFT6mq now has proper 📷 focus, and it finally feels usable.

Build it yourself (for now): https://codeberg.org/sdm845/linux

#SHIFT6mq #MobileLinux #LinuxMobile #sdm845

On a bit of a streak today 🔥

Work in progress, but already a big milestone: the camera sensor on my SHIFT6MQ is up and running 📷

Still a lot to refine, but seeing the first photo come through feels great. Sharing the very first shot taken on mainline Linux with it 👇

#RabbitHole: @okias is doing a lot work to mainstream #sdm845 patches to the #linux kernel. During a meeting of Phosh.mobi e.V. members I learned that there seem to be not many testers for #Shift6mq #axolotl. I still had a broken Axolotl sitting on my desk…

• repaired the phone that originally had been bought as part of a #ShiftPhone8 deal
  • cleaning inside (residue from water contact)
  • new display (two lines of broken pixels)
  • new usb-c pcb (didn't charge, data broke during testing)
• learned about edl to recover if phone wouldn't boot to fastboot anymore (yes, really had that situation later 😉)
• learned about the difference of fastboot and fastbootd mode
• learned about u-boot and the boot chain on the phone
• learned about dynamic partitions used in Android and how to use them from #linux
• learned about pmbootstrap
  • to build my own device images (mixture of existing axolotl and sdm845 to be compatible to the phone and the usage with u-boot and dynamic partitions)
  • changed pmbootstrap to build small (92M) boot image for boot_a/b partition
• tried to get more space for out of the phone for boot & root than provided by boot_a/b and system_a/b
  • resized userdata of Android
  • created two additional partitions for postmarketOS
• learned how to recover from kernel not booting without re-flashing
  • u-boot usb mass storage mode exports the mass storage of the phone over usb-c
  • phone connected to an aarch64 system (#Librem5 running #Mobian)
  • mounting encrypted partition, boot and what-else is needed
  • installing kernel packages via apk while in chroot on Librem5
• learned how to compile a kernel using ./envkernel.sh and pmbootstrap

Now I'm quite sure I can recover from any failure I will encounter while testing sdm845 kernels and I have the following setup on my Shift6mq:

• ShiftOS-L with small userdata partition in slot_b
  • applications for demoing the phone installed
  • work profile to contain closed source applications
• postmarketOS edge installed on partitions behind userdata
  • u-boot on rescue_a
  • 1GB pmOS_boot
  • 60GB pmOS_root
  • applications for demoing
  • multi-user: my testing user, demo user
  • everything except cameras work
• dual-boot possible on-the-go: enter fastboot (by holding vol-up at start), change slot, reboot

I put my notes on the postmarketOS wiki.

I started two merge requests:

• support audio configuration when started through u-boot in alsa
• add support for booting using u-boot and dynamic partitions to axolotl

I'll carry the phone at #clt2026 - Chemnitzer Linux Tage 2026 - on saturday 28th this month. I'll mostly be around the "Linux on Mobile" booth.

Broken #shift6mq #postmarketos phone - oops I did it again...

Be very careful with #qbootctl because it can brick your phone.
