usb boot on pi3

Mon Feb 29, 2016 10:03 pm

I know this is probably everywhere but with the release of pi3 could someone indicate how to set the system upto to run noobs of a usb drive is this even possible or is it just the os that runs on the usb drive? And you still need something on the sd card?

you can boot from USB and from network on the Pi3 without a MicroSD at all
The tools are still not public though

Tools to make a bootable image perhaps?

Maybe just a suitable bootcode.bin file needs to be created.

I don't believe that will ever work on a Pi3, because of the USB hub. Maybe on a pure A3 or a compute module.

AFAIA the LAN9514 does have the PXE feature if implemented: http://www.microchip.com/wwwproducts/en/LAN9514

There are references to "BCM2710 Boot" (the old USB boot with updated part number) & "Raspberry Pi Boot Generic STORAGE DEVICE 0250" in bootrom, suggesting two USB boot modes, but surely only relevant to 3A or CM3, or user-modified 3B.

Unless the base USB data lines are brought out to the micro USB power connector.

You could be on to something there, PP2 / PP5 perhaps, needs confirmation?

The bootrom on Pi3 supports USB mass-storage class booting as well as tftp/PXE boot. What isn't in place yet is a bootcode.bin that understands it's been loaded from a USB device (and therefore should go look for a USB device/listen on tftp for start.elf).

Hi,

are there some news?

When could we probably be able to boot from USB only?

Kind Regards

Sometime between now and infinity. The Foundation never releases a time line or progress and the latest is they are still working on it.

Hi,

so you also don't know it.
Let's them post it when they know it or release it.

Kind regards

That is not the same as booting from a USB device, you will still need an SD card to boot from...

BTW: you don't need to use berryboot to have the root filesystem on a USB HDD

I suspect the local star (known as "The Sun") will go to a red dwarf before we reach infinity (or the Restaurant at the End of the Universe). Hopefully the RPI3 USB boot driver will appear sometime before that event.

It's probably ready now.

The probability may be very low. But probable none the less.

I've hooked up Pi3 to Ethernet and power up without SD card. I don't see any DHCP request packet usually initiated by PXE boot. In fact, the Ethernet link LED is not blinking at all without SD card. How does the bootrom on Pi3 load anything from tftp server?

I think that it's BOOTP

Yes, the PI doesn't even enable link on the LAN port.
I have sniffed on the port with wireshark and couldn't see any packets as well.

That doesn't look good for one of my most wanted features ):
