Loading the u-boot-dtb.img binary via USB

Embedded Linux Discussions

Hello everyone,

I’m new to linux.

At this section: Bootloader: imx_usb_loader

I received different behavior on my local ubuntu host and ubuntu on vm(windows host, virtual box V6.1.18). Anyone knows what’s wrong with my local ubuntu?

On my vm ubuntu, it ran successfully:

That’s very odd, what release version of ubuntu? I can test it in the lab here…

(normally i don’t trust VM’s, just odd it worked for you…)

Hi Robert,

It’s very odd indeed. I create both vm and local machine recently, I am pretty sure they are running the same install. Could it be hardware/driver issue?

This is my vm ubuntu
