Jetson Nano does not boot up

english0815 · June 14, 2019, 6:25am

Hi,

I meet a problem when the Jetson Nano boot up.
When I try to boot up my Jetson Nano, it show below messages and then get stick.
My micro SD card is “SanDisk Extreme microSDXC UHS-I (V30)(A2)128GB” and the power supply is 5V4A.

Any thing I can do for this? Any help is appreciated.
Thanks.

Hi english0815,

Did you use sdkmanager to flash your sdcard?
Did you format the sdcard before setup?

english0815 · June 14, 2019, 8:18am

Hi WayneWWW,

I used “SD Formatter 4.0” to flash the sdcard and then used “Win32 Disk Imager” to burn the image.
Is it necessary to use sdkmanager to flash the sdcard? Or I can use the tool “SD Formatter 4.0” to instead of “sdkmanager” to flash the sdcard.
May I know how to use sdkmanager to flash the sdcard?

Thanks.

Hi,

Be sure to supply enough power to the Nano using a short and good USB cable or use the plug. I used a long (and not so good) cable first. I had trouble booting and the Nano destroyed three SD cards before I found that my cable was not good.

I have no knowledge about the way the Nano boots nor the errors shown in your log, but since it complains about an invalid partition your SD card may be broken too.

When I enter a broken SD card into a linux computer and look at the partion table using fdisk and command p the SD card only has a capacity of 12G, about the length of the Nano image written on it. Originally they had a capacity of 16 and 32 Gb.

Best regards,
Luc

When the Nano first boots, it’s / partition is expanded to fit the extents of the drive using resize2fs. It is 100% normal that there be a bunch of partitions not fitting the whole drive before the first boot. This happens on Pi as well. It’s a problem unique to flashing an image to a card of arbitrary size. Easy way to fix is simply to expand the last partition on boot so that’s what the distros do.

Hi WayneWWW,

I try to use sdkmanager to flash the sdcard and install sdk on Ubuntu 18.04.
Many errors occur like below messages when I execute sdkmanager command.
Any comments are appreciated. Thanks.

If you are using a VM, then this will cause failure. There is no official support for using a VM host, but people do get this to work if they manage to bind the USB to the VM. During flash USB will disconnect and reconnect…if the VM loses the USB and does not reacquire it, then this will fail.

Another issue is that the flash software does not necessarily detect that the host has all necessary packages. Python2 is one such package which is needed but not tested for. If you are on your host PC, then try this prior to flash:

sudo apt update
sudo apt --fix-broken install
sudo apt-get install libgconf-2-4 libcanberra-gtk-module
sudo apt-get install python

WayneWWW · June 19, 2019, 6:40am

Any update? Is this issue resolved?

english0815 · June 20, 2019, 7:56am

Hi linuxdev,

Thanks for you reply.
I finally to change the environment from VM to physical PC.

english0815 · June 20, 2019, 7:57am

Hi WayneWWW,

I follow the below steps to flash mmcblk0p1, then the Jetson Nano can boot up successfully.

May I ask you two questions?

What is included in eMMC (mmcblk0p1)? Why do we need to flash the eMMC by flash.sh?
Is there other ways to obtain flash.sh in addition to download it by running sdkmanager?

Copy the image to your sdcard first
Put device into recovery mode
Flash with below command:
$ sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1

WayneWWW · June 20, 2019, 9:15am

Hi

Sorry that there are still no standalone tarball for jetson nano driver package.
It is not emmc on Nano. It should be the sdcard.

english0815 · June 20, 2019, 9:57am

Hi Wayne,

In flash.sh, I saw the usage to describe how to use the script “flash.sh”.
As you said, the mmcblk0p1 should be sdcard.
I am confused that what difference between the mmcblk0p1 and mmcblk1p1?

# Examples:
# ./flash.sh <target_board> mmcblk0p1                   - boot <target_board> from eMMC
# ./flash.sh <target_board> mmcblk1p1                   - boot <target_board> from SDCARD
# ./flash.sh <target_board> sda1                        - boot <target_board> from USB device
# ./flash.sh -N <IPaddr>:/nfsroot <target_board> eth0   - boot <target_board> from NFS
# ./flash.sh -k LNX <target_board> mmcblk1p1            - update <target_board> kernel
# ./flash.sh -k EBT <target_board> mmcblk1p1            - update <target_board> bootloader

WayneWWW · June 20, 2019, 10:10am

Hi english0815,

flash.sh is a general tool for nano/xavier/tx1/tx2. What the comment says is not always right to Nano.

mohammed.ashraf · November 3, 2019, 1:19pm

Hello Wayne,
We have the Jetson Nano Production version which has only an eMMC , no SD card onboard.
When we try to flash it with L4T using the command $ sudo ./flash.sh jetson-nano-qspi-sd mmcblk0p1

The log as shown below stops at this point

[ 1.5030 ] Applet is not running on device. Continue with Bootloader
[ 2.2460 ]
[ 2.2504 ] tegradevflash --oem platformdetails storage storage_info.bin
[ 2.2534 ] Cboot version 00.01.0000
[ 2.2599 ] Saved platform info in storage_info.bin[/code][/code]

Do you have any clarification for this issue ?

WayneWWW · November 4, 2019, 3:28am

Hi,

What carrier board are you using?
" jetson-nano-qspi-sd" is not for the nano with emmc. You have to flash it with jetson-nano-emmc.

mohammed.ashraf · November 4, 2019, 9:29am

I’m using the Auvidea JN30B Carrier board
and right now I tried flashing it using this command$ sudo ./flash.sh jetson-nano-emmc mmcblk0p1 but stuck for more than an hour at

Making system.img…
populating rootfs from /media/muhammed/Me/NVIDIA/target/JetPack_4.2.2_Linux_GA_P3448-0020/Linux_for_Tegra/rootfs …

Any advice ?

WayneWWW · November 4, 2019, 9:40am

Populating system.img requires almost 15 mins. Stuck at here for one hour sounds abnormal.

Could you share the environment of your host?
Do you have sufficient size of disk?
Is this a pure jetpack/sdkmanager driver package?
