> RPi 4 from about a month or so ago onwards will do this out of the box Are you saying you don't need an SD card at all and it will just boot off USB?

  Yes, it can do that now.

    I buy quite a few of them as a tinkerer and recent (~two months) ones don't need firmware/BIOS fiddling to boot off USB. Make sure you get reasonably recent stock.

    Is the documentation outdated? https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/bootflow_2711.md https://www.raspberrypi.org/documentation/hardware/raspberry... says “USB booting is still under development“ and https://www.raspberrypi.org/documentation/hardware/raspberrypi/bootmodes/README.md https://www.raspberrypi.org/documentation/hardware/raspberry... says “The Pi 4B bootloader currently only supports booting from an SD card.”

      Two minutes ago I plugged in a RPi 4 with no SD Card in it. It does have a USB stick plugged in.
