On RaspPi 3B+..why can’t boot PiStar from USB

[KI5MEF]

Raspberry Pi 3B+ supports booting from USB drive .. and will using Raspberry Pi OS .. However, a Pi-Star image will not boot the Pi from a USB drive .. Why not?

Hi,

None of the Pi can boot USB devices, you need tweak the bootloader config for this:

I've done that on a Pi 4, to make it boot an SSD.

None of the Pi can boot USB devices, you need tweak the bootloader config for this:

From the documentation you referenced. Booting from USB mass storage is possible.

Code: Select all

On the Raspberry Pi 2B v1.2, 3A+, 3B, and Compute Module 3, 3+ you must first enable USB host boot mode. This is to allow USB mass storage boot, and network boot.

Yes, after changes to the bootloader config. But by default, a Pi boots the SD card only.
With a Raspbian, you can now use the raspi-config tool, which handles all of this.

Not a RPi 3B+. It is listed right in the document you posted.

Code: Select all

Raspberry Pi 3B+
The Raspberry Pi 3B+ supports USB mass storage boot out of the box.

Ah. I might test this tomorrow.
