How to enter flash mode

Installation

Make the following changes in the EFI setup application:

EFI Config Option Value
Secure Boot Disabled
Linux Boot Enabled


Note The Linux Boot option must be enabled, see pmaports!5027 for more info.

Use pmbootstrap to build your own installation image.

$ pmbootstrap init
$ pmbootstrap install --fde

The most straight forward way to install pmOS to the local nvme disk, as least until ondev2, is to build a USB drive with a pmOS install, boot it, then use pmbootstrap to build/flash an image to the nvme disk. The process looks something like this:

$ pmbootstrap install --disk /dev/<usb disk> --add pmbootstrap
# Boot the usb disk on the laptop
$ pmbootstrap init && pmboostrap install --disk /dev/nvme0n1

WWAN / Mobile Data

With pmaports!4718, mobile data should be working after you enable the FCC unlock script for the modem. The most straight forward way to do this is by just enabling all scripts by:

$ sudo ln -sft /etc/ModemManager/fcc-unlock.d /usr/share/ModemManager/fcc-unlock.available.d/*

GPS

Some initial support for GPS seems to be working, though I haven't been able to get geoclue to use it as a source yet:

$ mmcli -m 0 --location-enable-gps-raw --location-enable-gps-nmea
successfully setup location gathering
$ watch mmcli -m 0 --location-get

It might be working fine on UIs that configure/start geoclue by default, that's TBD.

Camera

Camera is now supported with custom kernel branch with camss patches and custom libcamera. The Spectra DSP is not supported so the RAW images have to be processed on the CPU using soft IPA.

$ cam -l
