Raspberry Pi 3 B+ Boot & Flash from USB to microSD?

Has anyone figured out how to do this?

I currently have to flash the microSD directly from a laptop, then use it to boot the Pi. That’s far less scalable than having a single USB that I can plug into a new device, flash it, then move on to the next.

The web suggests that B+ enables USB boot by default, but I only get a blank screen if I try to boot with a Resin image burned with Etcher.

Thanks,

Hi, we’re currently looking into this, but it appears that the RPi 3 B+ currently does not enable usbboot with a blank SD-card by default.

What the RPi 3 B+ does enable by default though, is booting from a USB attached mass-storage device instead of from the SD-card – if that’s what you mean?

Regarding the blank screen – what Resin image are you flashing?

@jhermsmeier I just tested again - flashed a USB stick with v2.12.5+rev2 in production mode and tried to boot with a fresh SD-card in the slot but it never initializes the display. The power to the display never comes on. If I flash the SD-card with the image, it powers up fine.

ok I’m having the opiset thang happen to me. etcher will not take the noobs os and put on a flash or a sd. gives me there error say invalid image. I was told this works with zip. files. running v1.4.4 of etcher on a win10 os.

Someone Please Help??
I’ve been trying to simply flash my SD Card and my SSD External Hard Drive and I get nothing. First of all. How do I download ETCHER so I can flash it?? The file I downloaded will not allow me to do anything. Can someone please HELP ME??

@Omega NOOBS is not a disk image, but an archive of files which requires a different installation mechanic (see https://www.raspberrypi.org/learning/software-guide/quickstart/ for details on that) – if you want to flash Raspbian with Etcher, you’ll need to download one of the full disk images available from https://www.raspberrypi.org/downloads/raspbian/

Hey @bob.srw

How do I download ETCHER so I can flash it??

You can download Etcher from https://etcher.io, selecting the fitting download for your operating system from the dropdown, or the “Downloads” section at the bottom of the page.

The file I downloaded will not allow me to do anything.

Which file did you download and from where?

Hi,
did someone find a way to flash RPI SD card by plugin an USB stick? like process used to provision up-board devices.
