boot from the usb ports

Thu Dec 21, 2017 7:11 pm

Hi all
I have another post, Can I put the sd card into the usb sd card reader that came with my kit and put it in one of the usb slots on the board and boot from that? if so what is the procedure for this (sorry i'm new to this.).

Thanks all for putting up with my simple requests

The quick answer is no, the more correct one is "not easily/simply" . In effect you're wanting to boot from a USB stick/drive**, which can be done, but, IIRC, depends on the type of pi you have and may not gain you much since, again IIRC, the uSDHC card slot can no longer be used for "data storage etc." if that's what you were hoping to achieve. To put it another way, whilst there are good reasons to enable/use USB booting, AIUI either the uSDHC card slot (+ uSDHC card) is still needed for the early boot stages or is effectively made "redundent". Do you have a specific need to boot from USB via a uSDHC card (eg. perhaps to improve physical card access) or were you just curious?

Still running Raspbian Jessie or Stretch on some older Pi's (an A, B1, 2xB2, B+, P2B, 3xP0, P0W, 2xP3A+, P3B+, P3B, B+, and a A+) but Buster on the P4B's. See: https://www.cpmspectrepi.uk/raspberry_pi/raspiidx.htm

Yes I have a reason for wanting to boot from the usb port. this is my daughers pi and she got it for xmas and I was hooking it up to her tv and I inserted the sd card too hard and broke the sd card holder. I thought i could put the sd card in the usb reader-writer that came with the kit and I would be out of hot water but I guess i'm not lol .well I'll have to buy another mother bd. thanks anyway
thanks

Unfortunately the answer is no, like Trev says.

There is a way to enable booting from USB on the Pi 3B (and possible recent Pi 2B), but to set it up you would need to boot once using an SD card with a special option in config.txt. After doing that you wouldn't need to use the SD card ever again.

If you have good soldering skills perhaps you can solder on a temporary external SD card socket using short wires and boot the Pi once with that?
