Booting from USB stick

Is it possible to boot from USB stick instead of SD card?

Would it be faster to boot from USB than SD? SD max rate is 10 MB/s.

 

from what I know, it might be possible eventually. but as of right now, you can only boot from the sd card, you can place the filesystem on the usb stick though, same as you can on the quads to put it on the sata drive..

its achieved the same way, getting to the uboot menu, and setting the root enviroment variable. and then saveenv

 

As Fire says, boot from SD card only until further notice (but you can put the Filesystem/OS on SATA/USB etc).

SD isn't limited to 10MB/s, but the reasonably cheap cards (8GB UHS-I HC £4.50/€5/$7.50) do give you 18MB/s read & 7MB/s write... which is actually plenty for an enjoyable experience.

 

Has there been any headway on booting from the USB. Am starting to get more interested in running the Udoo more and really would like to use my 64gb usb key instead of the MSD cards

 

Same as before for the moment, you still need a microSD card for booting the board.

 

That being said, though, you CAN still set it up where you start the boot from the microSD (which should be completely read-only) and then have it kick over to a rootFS that is on a USB thumb drive.... Just set it up the same way that we do for the SATA drives...

 

What is it that make the processor boot from SD?

Because I'm developing bare-metal code and I'd like to be able to boot from USB. I have no problems booting the bare-metal code from SD, I just was wondering how can I boot from USB because to be inserting and removing the SD could damage the slot.

Thanks!!

 

For a Udoo Dual/Quad perhaps you can change this procedure to USB instead of SATA.
For a Neo this is not possible.

 

Another option for a Neo is perhaps booting from a network (netboot): http://www.udoo.org/forum/index.php?posts/15672

 

That solution doesn't work for me because I'm developing bare-metal code for both the A9 and the M4. The reason I'm looking at the possibility of booting via USB is because I don't want to break the microSD card slot due to excessive insertion and removal of the memory.

 

Why does netbooting not work? On what OS is your A9 running (I don't completely understand the "bare metal" here)? If it is Linux you can add netboot to your image.
Perhaps you better ask this on the NXP forum https://community.nxp.com/community/imx Here are most users working with the Udoo environment.

 

Bare-Metal essentially means no OS, or in this case no Linux at all, nevertheless, we are planning on using an RTOS (threadX or FreeRTOS) so without Linux anything applying to Linux is going to work here.

I'm already participating in the i.MX6 Freescale community but I haven't received all the answers there, that is why I'm posting here as well because it allows me to reach a bigger user base. Maybe the i.MX community does not have the answers and here I can find help from another person that is not in the Freescale community.

 

As a mechanical alternative you could use a "micro SD card extender"

The X86 is hyped as a 'normal' PC. Selecting the order of available boot devices is a configurable thing for every PC I have work with. Usually holding down one of the function keys while booting gets you to a menu for this and other configuration functions. Guess that isn't available on the UDOO X86? It would be nice to be able to boot from a USB drive.
