Error when updating to 8.9

Troubleshooting
27

I have attached a SSD external drive, nothing else.

There’s an error here:

[    2.268315] gpio-backlight backlight: Error: The gpios parameter is missing or invalid.
[    2.268859] gpio-backlight: probe of backlight failed with error -16
[    2.272478] gpio-10 (i2c@0): enforced open drain please flag it properly in DT/ACPI DSDT/board file
[    2.274057] gpio-11 (i2c@0): enforced open drain please flag it properly in DT/ACPI DSDT/board file

:flushed: yes I changed the LED config using DietPI-led_control (disabled all), but I already tried to reset it.

Could the led service be the cause for dev hang?

I found another very weird thing, the command that I use every day and with cron to turn on-off the attached screen in the night…doesn’t work anymore :open_mouth:

root@Pi-Hole:~# echo 0 > /sys/class/backlight/rpi_backlight/bl_power
-bash: /sys/class/backlight/rpi_backlight/bl_power: No such file or directory

But I’ve never deleted, or modified, or even touched something related to it!

How can I install-reinstall the package/s related to backlight for LEDs, screen, etc…? I have no idea which apt packet is because I’ve never deleted it? (is not the RPi-backlight python module, I’ve never installed it). Or something to check if all the packages are installed, repair DietPI, I don’t know… otherwise I have to reinstall all I think.

29

Hmm that sysfs entry must exist. It’s created by the kernel at boot. It is used by official RPi services as well: raspberrypi-sys-mods/raspberrypi-sys-mods.rpi-display-backlight.service at master · RPi-Distro/raspberrypi-sys-mods · GitHub

How is the external SSD powered, via dedicated PSU or via USB only? Does it work reliably?

It seems you have I2C enabled. Do you require it for something, else could you try to disable it?

30

Exactly, it was there until few days ago. I have no idea why it disappears.

The external SSD is USB powered and it works very well.

Enabled? I’ve never enabled it… DietPI tool reports it as OFF.

What’s is going on in my Pi-Hole? :joy: maybe a clean install and a restore of Pi-Hole data will fix it… but I still would try to fix it if possible.

31

Let’s try to reinstall the kernel:

apt install --reinstall raspberrypi-kernel raspberrypi-bootloader

Also can you show:

grep -v '^[[:blank:]]*#' /boot/config.txt

EDIT: While currently nothing indicates it explicitly, at least you could try to put the SSD into a self-powered hub/docking station. The RPi USB ports are not designed to power 2.5" drives. The overall 6 W max power are easily hit on usage peaks and during boot, causing possible issues.

Done it, without success… at the boot is still stucked for 2 minutes.

Here it is (I removed the huge blank spaces), as you can see I have never enabled the I2C interface.

Yes, sorry, what a stupid, this RaspberryPI 4 doesn’t have anything attached to it, is another RaspberryPI that I’m using as a Prometheus and Grafana server that has the NVME disk attached.

(PS: the RaspberryPI with the SSD is running perfect with DietPI and the latest update… only this RaspberryPI/Pi-Hole has this weird issue)

33

Okay… I was annoyed and

I’ve just reinstalled everything :slightly_smiling_face: and I found the issue! Finally

The trouble is that when I enable the driver for the Pimoroni HyperPixel screen it hangs at boot!

As soon as I add to config.txt

dtoverlay=vc4-kms-dpi-hyperpixel4,rotate=270
dtoverlay=vc4-kms-v3d

The boot hangs for 2 minutes. I have no idea why. Just comment the lines above and it starts in few seconds (but obviously the screen doesn’t work without the two lines/drivers).

I see from the changeling that you @MichaIng have changed something in raspberrypi-sys-mods with 8.9. So this is the issue:

The raspberrypi-sys-mods package has been replaced with an own one, using only the small subset of the contained tweaks, which are useful on DietPi as well. A recent update of the package added a large number of dependencies, required for rpi-imager setup steps on Raspberry Pi OS only: MichaIng/DietPi#5734

If you want I can help you to investigate the issue, reporting logs, info, etcc… but at least I found the issue.

I can wait two minutes at boot, there’s no problem, I reboot it once in months but this issue should be fixed, because it can cause issue also with other displays I think!

tvservice is not supported when using the vc4-kms-v3d driver.

Okay, great that root found it.

The tvservice thing is known, but easier to just run compared to always first check whether KMS is enabled.

I’ll have a look into the raspberrypi-sys-mods package. Probably I missed something to port over.

Just to give another help, few minutes after the boot these errors appear:

IMG_7722.HEIC
IMG_7722.HEIC2000×1304 455 KB

This should be also why it enables i2c interface also if it’s set to off.

PS: the display is touch but I’m not using the touch, I don’t need it, I can disable the touch and test, but I don’t know how :smiley:

36

Ah, the issue then is that I2C is disabled while the touch screen driver attempts to use it. To disable it, set the overlay to:

dtoverlay=vc4-kms-dpi-hyperpixel4,rotate=270,disable-touch

Great thanks, this worked for the boot hanging but I’m still unable to turn the display ON/OFF using my “normal” command, do you know why by chance?

root@Pi-Hole:~# echo 1 > /sys/class/backlight/rpi_backlight/bl_power
-bash: /sys/class/backlight/rpi_backlight/bl_power: No such file or directory
38

I guess you need to activate the dtoverlay=rpi-backlight first. Just place it to the end of /boot/config.txt.

39

Great! This worked thanks!

But why with the release 8.9 all the dt-overlays are disabled/messed up?

40

I don’t know. At least from our side we did not touch the /boot/config.txt.

41

Uh, that’s weird!

Anyway sorry but I was wrong, your suggestion doesn’t work, if I add the

dtoverlay=RPi-backlight

then

echo 1 > /sys/class/backlight/rpi_backlight/bl_power

doesn’t give me the error but the display stay ON, doesn’t turn OFF. The command does nothing… :frowning:

42

I found in german RPi forum a post from 2017 (I know, it’s quite old) where they say, it doesn’t work when touch is disabled.

43

Thanks! No the touch now is disabled, but before 8.9 I was using both touch and I was able to turn off the display.

44

Found the solution to turn on-off the display! :partying_face:

That is too stupid to be real…but… something is different in 8.9, in order to turn on/off the display, the path is different

from

/sys/class/backlight/rpi_backlight/bl_power

to

/sys/class/backlight/backlight/bl_power

I spent days to try to load different driver from vc4-kms-dpi, the old vc4-fkms-dpi etc… but all that was needed was just to change the path :sweat_smile:

45

but this has no real relation to our DietPi version. We don’t maintain in /sys/class/backlight/backlight/bl_power or /sys/class/backlight/rpi_backlight/bl_power. Probably some other apt packages (like kernel) got updated in parallel.

46

I know! But for some reason something has changed,

I suspect this is something related to the

raspberrypi-sys-mods

Package that has been updated. Or the kernel or eeprom as you said!
