Wrecked my RPi 3B+ boot is looping now.

[McMelloW]

Dear forummers,

It is not Domoticz, but more the Raspberry Pi that is used to run domoticz.

I hope there is a Raspberry Guru out there to help me. I did the following commands

Code: Select all

sudo apt-get update
sudo apt-get full-upgrade
sudo rpi-update
sudo reboot now

The rpi did not boot but appears to be in a boot lopping, starting over and over again.
It is a headless Pi so I connected a screen and keyboard. The last thing I see is polkit.servce just below the RPi logo and the flash a blue-screen and starting again.
Flashed a new SD-card with the Raspberry Pi Imager, used this card to boot but no change. Is the Pi really wrecked? Who can help?

HI @McMellow.

Did you already try: https://www.raspberrypi.org/documentati ... -update.md?

If so, have a look at this Youtube movie: https://www.youtube.com/watch?v=aWYPVN2pekE

HI @McMellow.

Yes, I did this, but it did not solve my problem. But also with a fresh clean Buster the RPi is in boot looping.

I can try this, but I have to copy the image back on another SD card. Not available yet.

Huh?

But also with a fresh clean Buster the RPi is in boot looping.

Did you check the raspberrypi forum as well?
And how is it when you prepare an SD card with NOOBS?

Yes I did, I am searching since monday all over internet.

When I put this card in an older RPi 2B it boots like a charm.
So what is wrong with the card? Does a 3B+ uses other files then a 2B to boot? Is this an fstab problem?

And how is it when you prepare an SD card with NOOBS?

Can do that, what is the advantage of NOOBS (Never used it before.)

Hi, @McMellow,

Perhaps you can look to this thread as well: https://www.raspberrypi.org/forums/view ... 28&t=58151@

You can check the 3V3 voltage. If this has gone, I think you have to contact your supplier.

Hi folks, thanks for your support so far.
@HvdW I did the init=/bin/sh in the cmdline.txt There is no problems with the fstab file. No change, still a looping boot.
Haven't created a NOOBs sd-card yet. Have no spare cards left.

@FireWizard Checked the 3V3 value. This is OK. Studying at the https://www.raspberrypi.org/forums/view ... 28&t=58151 topic, this takes some more time.

Still wondering, I understand there is no flash memory at all on the RPi. How can it have boot problems with a brand new installed Buster?

[McMelloW]

Finaly!! It boots (headles) again, altough it is not very stable. Fortunately, I ordered a new RPi 3B+ so my Domomticz is up and running again.

After the looking at the fstab file and studying the https://www.raspberrypi.org/forums/view ... 28&t=58151 topic, I realized the 5V power supply is an issue. Attaching a keyboard and a mouse might consume to much power to get the RPi booting OK.

It is a more delicate board then I thought at first.

Everybody thanks again for all your effort and pointing me to right direction
