I noticed that booting my FP2 takes quite a long time. I use FP-open with an encrypted phone and no SD-card. When switching the phone on, it takes more than one minute until the password prompt for the decryption pops up. I created a bootchart, the pdf file is attached to this post.
bootchart.pdf (61.0 KB)
As you can see, in the beginning almost nothing is happening. Still it takes so long. Is this normal or expected? (I think not. Other phones boot much faster.)
If anyone is interested to record a bootchart themselves, I did it in the following way:
- I use termux to work with a terminal on my phone.
- I become superuser with
su
and then I modifyecho 240 > /data/bootchart/start
. This tells the system to record 240 seconds of data after the next boot. (When I’m done below, I remove this file againrm /data/bootchart/start
.) - I reboot the phone. Some files (
proc_ps.log
and others) are created in the folder/data/bootchart
. - I copy all these files to an empty folder on my PC and I pack them into a tar archive:
tar -czf bootchart.tgz *
. - I run
pybootchartgui bootchart.tgz
to create an image showing the boot process.
