How to install
The Librem 5 is not able to boot from SD card for now, so you must flash Mobian to the internal eMMC.
To do so, there are 2 options, both requiring that you install NXP's uuu
utility, for which you can download the latest release from Github (you can either build from source, or directly download the uuu
binary for Linux/x86_64).
Using Purism scripts
First, download the librem5-devkit-tools repo:
git clone https://source.puri.sm/Librem5/librem5-devkit-tools.git
Then, navigate to the librem5-devkit-tools
directory, and create a mobian
sub-folder containing the (uncompressed) Mobian image, renaming it librem5r3.img
.
Next, download the latest u-boot-librem5.imx
file from Purism's CI, and move it to the mobian
folder too.
Finally, put your Librem 5 in USB download mode by following the instructions provided by Purism, and execute the following command:
./scripts/flash-image --board librem5r3 --dir mobian
(Replace librem5r3
with librem5r2
if you have an Aspen/Birch/Chestnut Librem5, or with devkit
if you have the Librem 5 development kit)
Using Jumpdrive
Purism developer Sebastian Krzyszkowiak has an experimental version of Jumpdrive available for the Librem 5. In order to use it, you first need to install an ARM64 cross-compilation toolchain:
sudo apt install gcc-aarch64-linux-gnu
Then clone the repository and its submodules:
git clone https://source.puri.sm/sebastian.krzyszkowiak/jumpdrive.git cd jumpdrive git submodule init git submodule update
You can now build using the following command:
make initramfs-purism-librem5.gz
Finally, put your Librem 5 in USB download mode by following the instructions provided by Purism, and execute:
uuu src/purism-librem5.txt
Your Librem 5's eMMC should now appear as a USB drive on your computer and can be flashed using bmaptool
, dd
or Etcher the usual way.
