Re: Pi4 won't cold-boot occasionally (since lately)

Thanks also to MP and Fruit for your experience reports and ideas.

Re: Pi4 won't cold-boot occasionally (since lately)

This problem which I (and others) see, the "boot fails before BIOS/bootloader prints any messages, and red power LED stays on and green activity LED stays off and no blinking happens" , is this mentioned in some official FAQ? I read the sticky boot-problem thread , but I didn't see any men...

Re: Pi4 won't cold-boot occasionally (since lately)

This is pretty much a known problem with the Pi4. This is why I try to reboot my machine as rarely as possible, and I accept that when I do need to reboot it, it will take at least 2 or 3 tries to get it back up and running. This is very bad to hear. But thanks for answering, and for showing that I...

Re: Pi4 won't cold-boot occasionally (since lately)

Now as a hardware noob I'm surprised. I didn't know Pis could be that sensible. :-| So you're both saying that my new power-supply and its on-off-switch could cause the ~5% cases of cold-boot failures which I experience with my Pi4 (rev 1.1) ? (It's this Miuzei Pi 4 Power Supply by the way.) Now why...

My Pi4 run for two years with another power-suply (5V 3A USB-C) which also had an on-off-switch, without any problems. (I never used an official Pi foundation PSU with my Pis.) Also, the new power-supply works fine when the Pi4 boots, also under CPU/GPU intensive tasks. No indicator symbol appears o...

Re: Is Java Swing a good choice for these three things?

Since JavaFX replaces the out-dated Swing, and both JavaFx and Swing are new to you, it's better to start with JavFX. Also JavaFX's Opensource GUI designer tool Scene Builder is very professional. You can create stable and complex GUIs with it (in contrast to Netbean's Matisse Swing GUI designer, wh...

Dear Pi users and makers, My good old Pi 4B (Rev 1.1) with 4 GB of RAM and 64 GB µSD card run fine with standard up-to-date Raspbian for about two years and basically every day usage, rock solid i.e. stable. But since a few weeks it sometimes won't cold-boot in the following way ("sometimes&quo...

Re: Backup of µSD with Rsync works, but restoration doesn't boot?

rsync -aAXxv Thanks, with your additional rsync switches it works. So the method is: 1) create a backup with rsync, 2) rsync the backup to an empty card. or use rsync --delete to delete obsolete files, 3) In case of a new card, change its fstab's PARTUUID like HawaiianPi described.

Thank you HawaiianPi for this important hint. I'm going to try that. However, because my effort to restore from the rsync-backup didn't work in the first instance, I created with gnome-disks an mirror.img file of the entire source SD-card, and wrote this image file to the replica/target SD-card.
