Can not create image

Question

Can not create image

lhlong opened this issue 4 years ago · comments

Hello,

Thank for your tutorial at https://pythops.com/post/create-your-own-image-for-jetson-nano-board
I follow step by step on your tutorial, create a root is okay.
But, I got the error while trying to create the image with this command sudo -E ./create-image.sh
Jetson nano 32.3.2
Anyone had the same issue?

Did you update the BSP in create-image.sh script ?

BSP=https://developer.nvidia.com/embedded/r32-2-3_Release_v1.0/t210ref_release_aarch64/Tegra210_Linux_R32.2.3_aarch64.tbz2

No, I didn't.
I checked your script. It had the same version r32.2.3

which OS do you use ?
If you are using an OS other than GNU/Linux, I doubt it would work.

@pythops

Same issue as the poster.

Can you clarify how we should be building this? I tried to build this under the WSL platform (Ubuntu 18.04), then under a HyperV Ubuntu 18.04 (x64 also) image, but both fail - (exec format error).

Run debootstrap second stage... chroot: failed to run command ‘/bin/bash’: Exec format error

I was able to get past the bad format exception by building this on the Nano (aarch64 obviously)... but during the ./createimage.sh process it fails on another exec format error

looking at the file its trying to execute:

/jetson_build/Linux_for_Tegra/bootloader# file tegrarcm tegrarcm: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), statically linked, for GNU/Linux 2.6.8, with debug_info, not stripped
Looks as if I need an x86 machine for the create.

Can you post your recommendations for building the image on your blog page? At least then we know we am building using the correct cpu platform / OS.

This is a very useful page you have created - The bloat in the NVidia image is not suitable for a production system at all. Plus adding your ansible components was very helpful. Many props for this how-to.

Thanks!

@lhlong - Can you post what you did to get past this issue? I'm at the same spot. Thanks.

Just a follow up - looks as if I was able to create this on an Ubuntu 18.04 server / x64 system (not virtual).

Does not appear to work via Windows WSL:
Run debootstrap first stage... mknod: /mnt/c/Devel/badhare-jetsonimage_rootfs/test-dev-null: Operation not permitted

And a virtualized Ubuntu 18.04 appears to have trouble running the qemu parts preventing it from being successful.

Just a followup in case someone run into this on their own system.

I had this problem, managed to get around it by doing the first part (create-rootfs and ansible on the jetson nano)
then copying the rootfs to an ubuntu 20 machine (not VM) and do the second part (create-image)
