== Warning ==
 
 
Trying write to an SD card seems to always end up having it corrupted. And even worse: Also the internal memory seems to get corrupted. I have not tested if already reading an SD card can cause memory corruption.
 
 
== Installation ==
 
 
Follow the general installation instructions in [[Installation_guide]]. The <code>system</code> partition is rather small, so one might want to install to the <code>userdata</code> partition instead via
 
 
<source lang="bash">$ pmbootstrap flasher flash_rootfs --partition userdata</source>
 
 
== Setting the date ==
 
 
Since the rtc driver is read only you need to use ntp to set the date
 
 
<source lang="bash"># Install openntpd
 
$ sudo apk add openntpd
 
 
# Write the current system time to the hardware clock
 
$ sudo ntp -s</source>
 
 
== PostmarketOS kernel ==

== Graphics ==
 
 
Running X on the current version of the above kernel is very unstable, X usually crashes after a few minutes. The most recent kernel where X is more stable is qcom-msm8974-5.12.13, which is in commit [https://gitlab.com/postmarketOS/pmaports/-/commit/2ebc93b43e92b4eada0cefba70561642508b191d 2ebc93b43e92b4eada0cefba70561642508b191d] in pmaports. However, that version does not include a patch which makes the external power supply work.
 
 
So, if you want have both a mostly stable X and a functioning charger, change to pmaports commit
