GPIO rules about raspberrypi-ua-netinst HOT 17 CLOSED

Thanks, testing it now.

from raspberrypi-ua-netinst.

I have another rule 92-local-vchiq-permissions.rules with contents:

SUBSYSTEM=="vchiq",GROUP="video",MODE="0660"

But maybe this is Qt-ish related and doesn't necessary need a new setting.

from raspberrypi-ua-netinst.

Why belongs the vchiq rule to gpio? As I know, it's only needed if a user application needs direct access to the GPU. Please give a short explanation.

from raspberrypi-ua-netinst.

No the 2nd comment is another udev rule i had to add but it's not related to gpio, no. Should i open a new ticket for that?

from raspberrypi-ua-netinst.

Im using an eglfs Qt 5.7 app and without this vchiq rule the app wouldn't start.

from raspberrypi-ua-netinst.

I did a bit research and I'm pretty sure, that the vchiq udev rule is redundant.
Group video is set already without the rule:
crw-rw---- 1 root video 248, 0 Aug 5 15:05 /dev/vchiq
So adding the user to the group video should be enough.

Try the new commit dbba3ba, which has the two new installer variables. Feel free to close this issue if it fits to your conception!

from raspberrypi-ua-netinst.

Here's the problem I ran into without the vchiq rule: https://raspberrypi.stackexchange.com/questions/19436/how-can-i-permanently-fix-dev-vchiq-permission-errors. I'll do a fresh install and see what happens without the rule. Thanks for all the enhancements!

from raspberrypi-ua-netinst.

That would be curious because the rule doesn't change anything in result. Permissions and owners keep absolutely the same.
Maybe this was changed during the last 2 years... I'm expecting your report.

from raspberrypi-ua-netinst.

I found a c/p-mistake which didn't add the user to the system groups correctly and belongs to this, too.
So please checkout to 39ea9e2.

ha @FooDeas I was about to report an error my build ends with "/etc/init.d/rcS: line 885: syntax error: bad substitution". There we go again..

from raspberrypi-ua-netinst.

@FooDeas it's failing again (on a different line) with etc/init.d/rcS: line 880: syntax error: bad substitution. My configuration is:

disable_root=1
username=foo
userpw=bar
usersysgroups=lpadmin,input
user_is_admin=1
timezone=Europe/Amsterdam
locales="en_US.UTF-8 nl_NL"
system_default_locale="en_US.UTF-8"
gpu_mem=512
sound_enable=1
camera_enable=1
camera_disable_led=1
usergpio=1
usergpu=1

from raspberrypi-ua-netinst.

I used bash instead of ash for testing my code. That has led me to the usage of the wrong syntax.
Did you try it again with the new commit 7712ae3? This should fix all the substitution issues.

from raspberrypi-ua-netinst.

@FooDeas just tried again and everything installed fine. Unfortunately it seems sudo is missing and I have no way to install other packages.

foo@bar:~$ sudo apt-get install nano
-bash: sudo: command not found
foo@bar:~$ apt-get install nano
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
foo@bar:~$ /sbin/s
setcap             shadowconfig       slattach           sulogin            swapoff            switch_root        
sfdisk             shutdown           start-stop-daemon  swaplabel          swapon             sysctl   

See my config in prev comment.

This was broken with 39ea9e2. 9fb81c6 should finally do the trick.
I'll add some code sanitation because inconsistencies (from base repository) this afternoon and fully test it before merging that to master branch.
Nevertheless, you could use 9fb81c6 because the sanitation doesn't change functionality.

from raspberrypi-ua-netinst.

Tried again but still no sudo. I saw that during installation the following message was printed: Can't find package libraspberrypi-bin for inclusion. Is this maybe the issue?

from raspberrypi-ua-netinst.

I fixed everything and tested it (bf797fa) successfully, using your config.

(Notice, that disabling root has changed in current master branch.)

@FooDeas awesome it worked! And you were right, the vchiq rule isn't needed any longer.
