Stephan, sorry for the delay
No problemo. Clearly, it's not an emergency. Thx for your reply.

Hello,
Small issues, today, with dtoverlay gpio-shutdown/poweroff
[root@mypi ~]# dtoverlay gpio-shutdown su: user pi does not exist * Failed to apply overlay '1_gpio-shutdown' (kernel) su: user pi does not exist [root@mypi ~]# dtoverlay gpio-poweroff su: user pi does not exist su: user pi does not exist [root@mypi ~]#
That seems to come from here (https://github.com/raspberrypi/userland/blob/master/host_applications/linux/...). If you run as root, it tries to run as the user "pi", as a normal user(any), you shouldn't have that problem
well ... not so sure :-)
[stephan@myrpi ~]$ dtoverlay gpio-poweroff * Must be run as root - try 'sudo dtoverlay ...' [stephan@myrpi ~]$ sudo dtoverlay gpio-poweroff [sudo] password for stephan: su: user pi does not exist su: user pi does not exist [stephan@myrpi ~]$ dtoverlay -l Overlays (in load order): 0: gpio-poweroff [stephan@myrpi ~]$
Then, I don't understand why it needs to be run with SUDO from any user to gain ROOT access ?
[root@myrpi ~]# dtoverlay gpio-shutdown su: user pi does not exist su: user pi does not exist [root@CrisalidBox-C9A58C ~]# dtoverlay -l Overlays (in load order): 0: gpio-poweroff 1: gpio-shutdown [root@myrpi ~]#
Just funny :-)
Even if I add a fake user "PI", this does not work better.
[root@mypi ~]# useradd -r pi -p pi [root@mypi ~]# [root@mypi ~]# [root@mypi ~]# dtoverlay gpio-poweroff * Failed to apply overlay '2_gpio-poweroff' (kernel) [root@mypi ~]# dtoverlay gpio-shutdown * Failed to apply overlay '2_gpio-shutdown' (kernel) [root@mypi ~]#
That bit seems to come from here (https://github.com/raspberrypi/userland/blob/2448644657e5fbfd82299416d218396...), it fails to check if the overlay was actually applied
But when I check the overlay list, I get:
[root@mypi ~]# dtoverlay -l Overlays (in load order): 0: gpio-shutdown 1: gpio-poweroff [root@mypi ~]#
At least, something is done :-)
That is a little stranger, why does it say it did something when the command before said it failed???
Last problems: [root@mypi ~]# dtoverlay -h gpio-shutdown * Help file not found [root@mypi ~]# dtoverlay -h gpio-poweroff * Help file not found [root@mypi ~]# dtoverlay -h rpi-rtc * Help file not found [root@mypi ~]# dtoverlay -h rpi-display * Help file not found [root@mypi ~]#
I guess I'll have to add some debugging info and check in my rpi (as time permits)
In case ... [root@mypi ~]# cat /proc/version Linux version 4.14.65-v7.1.el7 (mockbuild@armhfp-03.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-28) (GCC)) #1 SMP Mon Aug 20 19:04:20 UTC 2018 [root@mypi ~]#
[root@mypi ~]# rpm -qa 'raspberrypi-vc*' raspberrypi-vc-demo-source-20170705-502.gitaa39775.el7.noarch raspberrypi-vc-libs-20170705-502.gitaa39775.el7.armv7hl raspberrypi-vc-utils-20170705-502.gitaa39775.el7.armv7hl [root@mypi ~]#
2 questions
- has it ever worked before?
Well... never tried before. I was just comparing the result between CentOS and R@spbi@n...
- which rpi exactly are you using? (don't know if it is really relevant).
Standard RPI 3b.
Thanks. Pablo.
Stephan.
P.S.: Today we built 4.14.71 and will be released as soon as it passes the tests.
Great ! What's new for RPI, I mean compared to 68, 69 and 70 ?
