How to boot from usb

Could I use an usb drive to be a boot device?
Need a micro sd card inserted to Nano?
Thanks.

I am not sure if the sd image is able to work on usb drive.
Below is the workflow from Xavier.

List boot from USB steps as below:
1. Check your USB disk is /dev/sda or /dev/sda1 on nano first.
2. Copy the root file system to USB disk
# insert your pen drive into Host PC. in most cases it will detected as /dev/sdb
# format the first partition as ext4
$ sudo mkfs.ext4 /dev/sdb1
# mount the pen drive
$ sudo mount /dev/sdb1 /mnt
# copy the root filesystem
$ cd rootfs/
$ sudo tar -cpf - * | ( cd /mnt/ ; sudo tar -xpf - )
$ sudo umount /mnt
$ cd ../
3. Flash:
$ sudo ./flash <borad name> sda (sda1)

I tried, but it failed.
There is no usb in boot_targets, and “usb start” cannot bring up the USB drive.

Then I found the following topic, does that mean I cannot use USB3 ports to load rootfs now?
https://devtalk.nvidia.com/default/topic/1049281/usb-3-boot-on-jetson-nano/
Thanks!

Did you put rootfs into usb drive?
I don’t think u-boot is able to drive xhci device now.

yes

It is a situation that your system roofs is not able to be ready because usb firmware is on usb drive itself…

sudo ./flash.sh jetson-nano-qspi-sd sda1

This flashes all partitions to the micro sd card, and uboot loads kernel from micro sd and kernel tries to use rootfs on /dev/sda1. The flash command only flashes extlinux.conf, Image, and dtb to APP partition on the micro sd card; however, tegra21x_xusb_firmware is on the usb drive. So should I copy drivers and libraries to the micro sd card manually?



Does tegra21x_xusb_firmware in my log equal to rp4.blob in RP4 partition?

If yes, when using “sudo ./flash.sh jetson-nano-qspi-sd sda1” command to do flashing, flash.sh does create all partitoins to the micro sd card, so I think rp4.blob also flashes to RP4 partition of the micro sd card. Am I right?

Then u-boot loads kernel from the micro sd card to memory and jumps to Linux kernel. When is rp4.blob read from RP4 partition?

In usb boot case, which device is rp4.blob read from, micro sd card or USB drive?

If rp4.blob is read from the micro sd card, why kernel cannot find it?

Thanks!

lonesomesnow,

Yes, you are right, rp4.blob is the xusb firmware. The current status is just simple.Just because u-boot does not support it yet and our developer is still working on it.

OK, wait for your update.
Thanks again!

L4T r32.2.0

I tried to flash boot from USB, it appeared a lot of failed services after I set user information at first boot time. But it still can boot successfully after I reboot it manually.
Is there something wrong in boot from USB?

Steps:

  1. Format my USB stick on host pc

$ sudo mkfs.ext4 /dev/sdb1 -L nano

  1. Flash Nano

$ sudo ./flash.sh jetson-nano-qspi-sd sda1

  1. Copy rootfs to my USB stick

$ sudo cp -a rootfs/* /media/victor/nano/ && sync

  1. Insert my USB stick to Nano and boot

Thanks!

Hi lonesomesnow,

For r32.2, external is being used as identification is solely on UUID based and not type of media.
