create-jetson-nano-sd-card-image.sh fails with no space left on device while creating image

I’ve updated the DeviceTree and am trying to create a new SD card image. I’ve performed the following steps:

  1. Updated the device tree files
  2. Re-build the kernel using the following commands:
TEGRA_KERNEL_OUT=build
export CROSS_COMPILE=${NVGCC}/bin/aarch64-linux-gnu-
make ARCH=arm64 O=$TEGRA_KERNEL_OUT tegra_defconfig
make ARCH=arm64 O=$TEGRA_KERNEL_OUT -j8

  1. This appears to update the DTB file located <SDK_install_directory>/nvidia_sdk/JetPack_4.2_Linux_P3448/Linux_for_Tegra/bootloader

  2. I then ran apply_binaries.sh (not really sure what this does)

  3. I then ran create-jetson-nano-sd-card-image.sh

sudo ./create-jetson-nano-sd-card-image.sh -o sd-blob.img -s 16G -r 200

This runs for a while and then prints out the following messages towards the end:

EALLY setting name!

The new table will be used at the next reboot or after you
run partprobe(8) or kpartx(8)

I should have plenty of room to create this image. Any ideas?

For some reason, my boot.img is 34 MB, the create-jetson-nano-sd-card-image.sh only allocates 655360 bytes for that partition.

Somewhere along the line some script grew the boot.img. I can’t find what would create that image. apply_binaries.sh appears to take the zImage and Image and puts them into the rootfs. But I can’t find what creates the boot.img.

Has anyone else seen this problem?

hello Shadowmind,

the script file create-jetson-nano-sd-card-image.sh generate the system image as a blob and save locally.
could you please run below commands to check if “–no-flash” options works.
thanks

$ sudo ./flash.sh --no-flash jetson-nano-qspi-sd mmcblk0p1

I can’t run this because I can’t get the Jetson LT4 installed. I removed everything and started with a clean slate, but now when I try and reinstall everything through the SDK Manager I get the following error messages:

You might be running into an Ubuntu bzip2 update bug. Haven’t verified it myself, but take a look here in case this is the issue:

Hi,

I don’t want to reopen this issue, but just share my experience.
I’m preparing a Jetson Nano SD card image inside a ubuntu18.04 docker container.
I download all the packages via sdkmanager cmdline and run apply_binaries.sh inside it.
This is working fine.
But, when I run

tools/jetson-disk-image-creator.sh -o sd-blob-b01.img -b jetson-nano -r 300

I get the following error:

dd: writing to '/dev/loopXp1': No space left on device

I run the container with --privileged.
I don’t know why (my host is running an up to date ubuntu 18.04 too), but “losetup -f -P” inside the create-jetson-nano-sd-card-image.sh script is not showing correct size when I do gdisk -l /dev/loop20p1, it’s something like 62MB instead of 4.7GB.

So my solution has been to patch the script with:
losetup -f instead of losetup -f -P
and use kpartx -a that will map the partitions to /dev/mapper/loopXpY
and kpartx -d /dev/loopX before losetup -d /dev/loopX

This solution is working inside my docker container and I can generate an image that is working fine on my jetson nano devkit.

Running jetson-disk-image-creator.sh on my host directly is working fine without any patch.

Here is my simple Dockerfile for people who are interested:

FROM ubuntu:18.04

ENV DEBIAN_FRONTEND noninteractive

RUN apt-get update && \
    apt-get install -y --no-install-recommends \
        pigz \
        lbzip2 \
        python \
        gdisk \
        sudo \
        kpartx \
        patch \
        zip \
        qemu-user-static && \
    # Cleanup
    rm -rf /var/lib/apt/lists/* && \
    rm -rf /var/log/* && \
    rm -rf /var/tmp/* && \
    rm -rf /var/cache/apt/archives/*.deb && \
    rm -rf /tmp/*
RUN useradd -m docker && echo "docker:docker" | chpasswd && usermod -aG sudo docker
RUN echo 'docker ALL=(ALL) NOPASSWD:ALL' >> /etc/sudoers

USER docker
CMD /bin/bash

“I am not a docker guy”, but once the image is covered by loopback (using the “-P”) you might want to run “lsblk -f” and see what it thinks of the device as a whole.

@tvlanaccess @Shadowmind

/dev is out of space

check by

df -h

you can increase /dev tmpfs by command for example:

mount -o remount,size=2G /dev
