Hi, I am currently working on building a completely customized rootfs following your documentation. I have managed to do that successfully using the QEMU emulator, creating the entire setup on an x86 host machine for my board. I am sure you know how slow the QEMU emulator is compared with a native…

So currently there’s no way to do that without QEMU, right? What if I wanted to build it directly on a Jetson? I think it’s feasible on ARM Linux/Jetson, but we don’t have the experience doing so. You may try if removing copying the QEMU executables from the scripts works.

I can install it, but not sure if I need it. I’m compiling everything on a ARM64 machine (Macbook M2) already, why would I need QEMU in that context?

Hi, the point is that even though you have a native ARM machine, and do not have to use QEMU to emulate an AArch64 architecture, binary formats on Mac and Linux are still not the same (Mach-O/ELF), so you cannot run executables (like dkpg for extracting packages) in the BSP’s rootfs. In short, I t…

Hi, is this also true if I’m compiling everything inside of a docker container arm64v8/ubuntu ?

I don’t know much about docker, but in theory, you wouldn’t need QEMU if your docker is correct. However, the l4t_create_default_user.sh uses QEMU and expects to be run from an amd64/x86_64 Linux host PC in order to execute ARMv8-a code. Going from Mac to Linux on Mac might differ versus Linux on an…

Hi, I think you may do it using Docker (though you’d still need to modify the script to bypass QEMU stuff), but Docker on Mac are done via virtual machines, not like the container mechanism on Linux, so there will be degradation in performance, which is also seen on x86 with QEMU. Given that, it m…

Are you unable to install qemu-user-static? You might find this of interest:

He’s installing that and binfmt-support:
sudo apt install qemu-user-static binfmt-support

Sometimes I think qemu-user-static might need to be installed first, not sure.
