You can already move most of the OS to a USB drive or USB hard disk using any version of the RPi. Then even an old 256 or 512MB micro SD card can be used for the boot files with very little effort.latinhawk wrote:What is the use of announcing a feature that is not available. The only reason I ordered a pi 3 was to have use of USB drive without the need of the sd card.
You must be pretty new to computers. This isn't a pi thing but it is common and always has been for marketing to trumpet the best possible outcomes while engineering is still trying to figure out how to make them work. And releasing before the software can do what marketing is already marketing, since we'll just fix with an update, is so common that I'd say it's pretty much guaranteed. It's nothing worth getting angry about, it just is what it is.latinhawk wrote:When a product is sent to market and it says it will do certain things I just expect them to happen or at least to tell me how to make it happen.
That made me laugh. Let's see, let's say you don't want to plug in an sdcard but you don't mind plugging in a USB flash drive, then there would be an advantage to booting straight from the USB. This might be due to having an extra USB flash drive but not having an extra sdcard. This might be even more of a problem if you've just got in your ten pack of pi Zeros.klricks wrote:I don't see any real advantage of having a USB only boot.
I never saw any official announcement that it was possible to boot without SD. Do you have a link?latinhawk wrote:Like I said I'm a user. I'm not competing with you guys. I just want a product I purchased to work as advertised or someone to tell me how. I'm a retired old man.

USB AND PXE NETWORK BOOT
Even with the chip designed and
taped out in March of last year, the
Foundation had some final input
for Broadcom in order to add two
new features: direct USB mass
storage and PXE network boot
capabilities. “Gordon rewrote the
boot ROM for the chip and then
provided an updated boot ROM to
Broadcom, saying ‘shove this in
the chip, it’ll work’,” Eben laughs.
“And it does!
“The other interesting thing
about the chip is for all other ones
the implementation work was done
entirely in Cambridge; this one was a
collaboration with Broadcom’s set
top box engineering group in Aztec
West [business park] in Bristol.”
Eben readily admits that not all
the capabilities of the new parts
are going to be used at launch,
It's possible but not yet with the current firmware and kernel.
The "small multi color square in the upper right hand corner" is (one of) the low voltage indicator(s). Does the red PoWeR led also flicker?latinhawk wrote:I finally recieved my Rpi 3. I updated my current sd card which is working on my pi2 but it won't start on the pi3. I get the multi color box with a small multi color square in the upper right hand corner. Of the two board lights only the red goes on. I tried with a different card withe the latest noobs but even though it starts it gives errors half way through the installation. Any new on the boot from usb? Any and all help will be appreciated.

The way you frame it, it doesn't make any sense.0xFF wrote:So, for cardless booting from the USB/ PXE we have to wait for new firmware and kernel... on the sdcard?DougieLawson wrote: It's possible but not yet with the current firmware and kernel.
I don't get it.
What if the reason it doesn't work now isn't that it isn't trying to do these things at the, I'm not sure what to call it because firmware is already used for the binary on the sdcard, call it firmerware, at the firmerware level. Maybe when it does try to do these things at that level, the higher level code doesn't know what to do. What I mean is that there is likely some sort of interface between the firmerware and the firmware that allows it to work, just putting the old firmware on the USB drive might not be enough.If there is PXE code in the RPi ROM, then should be some activity on the Ethernet interface when powering device up.
At lest a DHCP and TFTP request. The same fot USB boot.
