[Librem-5-dev] Birch image flashing

[Angus Ainslie]

Hi All,

These instructions will flash a full image onto the Birch devices. They
will wipe out anything already contained on the eMMC.

First you need to get the latest version of the uuu scripts. So clone
the librem5-devkit tools repo

angus at midas:/tmp$ git clone
https://source.puri.sm/Librem5/librem5-devkit-tools

Then grab the latest image and u-boot. They will end up here
https://arm01.puri.sm/job/Images/job/Image%20Build/ as "next librem5
amber-phone"

Then install uuu from mfgtools using 1 of the methods below

1) on PureOS

apt-get install mfgtools

2) on other debian based distros

angus at midas:/tmp/librem5-devkit-tools$ wget
https://repo.pureos.net/pureos/pool/main/m/mfgtools/uuu_1.2.31-0%2Bpureoslibrem5.2_amd64.deb

angus at midas:/tmp/librem5-devkit-tools$ sudo dpkg -i

Setting up uuu (1.2.31-0+pureoslibrem5.2) ...

3) On other Linux distros

angus at midas:/tmp/librem5-devkit-tools$ sudo ./scripts/build_uuu.sh -i

Ok now we're ready to flash the phone. Not doing these steps in this
order could cause the flashing to fail.

1) Take out the battery AND disconnect the USB C cable.

2) Hold VOL+ then insert the battery.

3) Plug the USB C cable in. The phone should now show up with "lsusb"

angus at midas:/tmp/librem5-devkit-tools$ lsusb | grep NXP
Bus 003 Device 024: ID 1fc9:012b NXP Semiconductors

4) Now do the actual flashing

angus at midas:/tmp/librem5-devkit-tools$ uuu uuu_scripts/flash_librem5.lst
uuu (Universal Update Utility) for nxp imx chips -- libpureos/1.2.91+0git6b465-62-g9c56e46

Success 1    Failure 0

5) Now power cycle the phone by removing the USB C and battery. Then
install the battery first before plugging in the USB C.

Your phone should now be running the latest image

Cheers

Angus
