Re: USB boot device

So then why haven't the boot rom version, or at least the USB boot order option already been deprecated out of raspi-config? There are still other use-cases in which it may be necessary to change boot order manually. E.g. for PXE network boot, which unlike USB boot is not enabled by default. (Altho...

Re: USB boot device

There are some other options you will need, like multiple steps in raspi-config, and making sure your eeprom is the right version. To be honest, I'm not sure why there isn't a "one and done" tool to do all this for you since it is easy to automate each check/step of the process so there would be 0%...

Re: ETA for reliable USB flash drive imager?

(2) It seems like the rpi-imager knows if the destination is USB or SD card at least some of the time, since the USB device showed up as a selection in the menu, and my SD card that the OS was running on was not shown as a choice. It can hide system drives (the drive mounted to / or c:\ ). And it c...

Re: ETA for reliable USB flash drive imager?

How could I have saved 8 hours of my time and the time of everyone who read my post and tried to help? By adding a 3rd selection to the rpi-imager -- Pi model for image. That way the rpi-imager could have checked for a legal combination of hardware+destination drive (USB, SD, etc)+OS and only allow...

Re: ETA for reliable USB flash drive imager?

@incognitum: I never said it was Noobs. Reread what I said carefully. I thought Noobs was just an installation program, but maybe I am wrong. No. NOOBS persists and is started on every boot to display the "press shift for recovery mode" thing, and to display a boot selection menu if you installed m...

I got the exact same error using two wildly different OSes.
Don't think so.
The recover4.elf file is pretty unique to NOOBS, and should not come with other images.

You may get a similar error about start4.elf though, if other operating systems like RetroPi have too old files too.

Re: ETA for reliable USB flash drive imager?

Don't think the firmware in the EEPROM is the problem.
If it complains the recover4.elf file on the USB stick is too old, it is reading the USB stick fine.

@incognitum: It would be nice if the rpi-imager and EEPROM boot loader just worked, since they are the official Raspberry Pi OS proiducts!
Doubt any operating system offered by rpi-imager itself installs recover4.elf

What image did you flash?

Re: ETA for reliable USB flash drive imager?

recover4.elf is not compatible Sounds like you are using NOOBS. So, as I originally stated, everything is up to date and the SD card copy did not work. "apt upgrade" only updates Raspbian. Not any other OS that may be on your card. If you are using NOOBS, try if it works better if you fetch a newer...

Re: ETA for reliable USB flash drive imager?

Doesn't the rpi-imager require an SD card rather than a USB flash drive? Imager writes happily to any external storage device. Does require a Pi that has USB mass storage booting enabled though (which on Pi 4 may require flashing EEPROM first, which does require a SD card). And that the image you a...

Re: Qt QApplication constructor taking very long time on Raspberry Pi python3 PyQt5

As far as I know (I haven't been physically in the lab, yet), the board has no mouse connected and the screen is not a touch screen. Don't think that happens just because there is no mouse. On a standard Raspbian install X still displays a mouse cursor even if no mouse is connected. Are you accessi...

Re: Qt QApplication constructor taking very long time on Raspberry Pi python3 PyQt5

Not sure what is up with that.
Think Xcursor is only used to control mouse cursor shapes. E.g. for switching from pointer to hourglass.
Not really a library that should be doing stuff that blocks.

Re: RPiOS32 Imager strange behavior

The "open file dialog" it is trying to display is typically provided by the window manager (LXDE/GTK), rather than drawn by imager itself.

Re: IP setting for Pi server installed in virtualbox to enable network boot for a number of Pi server connected to host

On the virtual Pi Server, the internal network ipv4 IP is 10.0.2.x/24 while the host LAN is 192.168.1.x /24 setting. For example, one of the physical PI3B+ board has an IP 192.168.1.13. Easiest is to use your 192.168.1.x network for everything, and not make things more complicated than that. In the...
