Boot Raspberry pi via USB

Wed Sep 11, 2013 7:47 pm

Hi,

I have a raspberry pi model B, and I want it to boot from USB instead of SD card.

Is there any way to boot without any kind of SD card?

Thanks,
Raspberrymaniack

Nope. Sorry.

AFAIK No, the bootloader can only read the SDHC card.
Why do you wish to do without a card? (Just curious).

@FTrevorGowen

As all of the SD cards I have right now are used for my cameras.

Also I am only 13 - I can't really afford to buy SD cards. I know that might sound stupid, but to get a class 10 SDHC card with a reasonable amount of storage, that can cost £15+ who only gets £5 from a paperround a week, it can be quite expensive.

If you have a small sd card you can have the bootloader on it and have it then boot from the USB card. Basically you would have nothing but the fat partition on the sdcard and root and home and whatnot on the USB.

Actually...you are probably better off staying away from Class 10 SD cards for the Pi. The sweet spot for speed and reliability appears to be around Class 4 to Class 6. Class 10 are "tuned" to handle large blocks of data at once, and that is not the sort of behavior that an SD card in a Pi will see.

I fully understand. However you only really need something like a 4Gb Class4 SDHC or micro-SDHC card + adapter to start with, especially if you already happen to have a spare USB flash drive about. You should be able to find 4Gb ones from, for example, amazon or an amazon store for around £5 or less if you're lucky. Many of mine are Kingston brand and I've had no problems with them.

If you are going to run with the Pi file system on another device then you can get away with really small SD cards for the boot partition as there is less than 50MB on the boot partition. I have managed to repurpose some I had lying around that are now too small to be useful for anything else.
