JetPack 4.2 flashing with VMware on Jetson AGX

[romeofilippo95]

I am using ubuntu on VMware and using the SDK to do the installation, but at around 30% stops and I cannot get the agx flash, so I had to navigate to

cd ~/nvidia/nvidia_sdk/JetPack_4.6_Linux_JETSON_AGX_XAVIER_TARGETS/Linux_for_Tegra
and run

sudo ./flash.sh jetson-xavier mmcblk0p1

So to get the AGX flashed and booted, but after I cannot install Cuda, Deepstream, Tensor and so on and I m using this script to proceed.

@linuxdev

cd ~/Downloads/nvidia/sdkm_downloads
# We will make a mirror of this directory on the Jetson, though only for Jetson related files.
ssh ubuntu@<tx2>
cd Downloads
mkdir -p nvidia/sdkm_downloads
exit
# You are now back on the PC. "arm64" is the Jetson architecture, amd64 is the PC architecture.
scp *arm64*.deb ubuntu@<tx2>:~/Downloads/nvidia/sdkm_downloads/
ssh ubuntu@<tx2>
sudo -s
cd Downloads/nvidia/sdkm_downloads
dpkg -i cuda*repo*.deb
apt update
# At this point you have the CUDA repos and apt can use them. Now add the VisionWorks repos:
dpkg -i libvisionworks*repo*.deb
apt update
# At this point you also have the VisionWorks repos and can add those packages.
# Now add what remains (those back quotes are important and executes the ls command and
# substitutes the result):
dpkg -i `ls *.deb | grep -v repo`

It broke a couple of times and had to do a sudo fix broken all. Now seems to be ok but I want to be sure that it is properly installed. At the moment I am running some cuda example and seems to be ok. Now I need to install OpenCV and I am referring to this script. Which I tried before and did not end up well.

My questions are:

How do I check that my installation is valid?
How do I install OpenCV without NVMe?

At the moment OpenCV 4.5 is installed and seems to work, I installed darknet from this tutorial and seems to work. Now I need to add YOLO and I might have to start over with this other repo

The “script” is probably a bit outdated, but might work ok.

You should know that the failure to complete a flash is due to the VM not being set up correctly to always pass the USB device (the recovery mode Jetson) through even if it disconnects and reconnects. That would be something to ask the VM people’s support about.

If your system is already flashed, then you can skip all of that manual install information and simply use JetPack/SDKM. What you’d do is to fully boot the Jetson without recovery mode, and then in JetPack/SDKM you would deselect flash and deselect any host side install and simply enable install of the components to Jetson. In this case it uses ethernet. The default is the IP address of the virtual wired ethernet on the USB-C, and this would then have to be set up in the parent host PC o/s to pass through to the child Ubuntu o/s (this is a “standard” USB ethernet device with no special drivers, so if it reaches the VM, then it could be set up).
