Describe the bug
PINN is continually rebooting. It won't load an operating system This happens when I press nothing -screen recording.

It also happens when I manually select RetroPie from the menu and click "boot" - screen recording.

I also went to the fix menu for RetroPie (the default boot OS), selected all 4 checkboxes, and everything seemed normal, I think - screen recording.

To reproduce
Plug in the RPi and wait.

Expected behaviour
After the timeout, RetroPie loads

Actual behaviour
PINN reboots infinitely, never loading an operating system.

System
Add answers to the following questions:

• Which model of Raspberry Pi? Pi4B
• Which version of PINN? 3.9.2, I think - log file shows "(Buildroot p3.9.2-4-g386d682d)"

Logs
Log file on pastebin

There are a few things I can suggest:

1. PINN v3.9.2 has a small mistake in its configuration, which is normally benign, but please see https://forums.raspberrypi.com/viewtopic.php?p=2290901#p2290901 for a small recommended fix.

There may be a problem with your bootloader as I see it is dated from 2020. I have only seen such repeated bootloops on a Pi5 which was due to an omission in the early firmware (see https://forums.raspberrypi.com/viewtopic.php?p=2173713#p2173713 for details), but you can do some quick tests as follows:

2. When the PINN menu appears, move your mouse to cancel the remotetimeout timer you have set, then press Ctrl-Alt-F2 to get to the command shell. Login with root/raspberry then enter rebootp 6 and see if your Pi boots into Retropie or PINN.
3. A further test is to create a file on PINN's recovery partition (/dev/mmcblk0p1) called autoboot.txt. Add one single line to that file that says: boot_partition=6. When you next boot your RPi, it should bypass PINN altogether and boot straight into Retropie. Does that happen? Please delete autoboot.txt afterwards.
4. Finally, once you have completed those tests, please see https://www.raspberrypi.com/documentation/computers/raspberry-pi.html#raspberry-pi-boot-eeprom for details on how you can update your bootloader to the latest version. You'll need a spare SD card, and possibly an installation of raspios-lite, depending on your choice of method to use.
