Jetson Orin Nano Tutorial: SSD Install, Boot, and JetPack Setup
The NVIDIA Jetson Orin Nano Developer Equipment can boot from a Solid State Drive (SSD). You may arrange your Orin Nano in underneath 45 minutes from the command line. Looky right here:
Background
The Jetson Orin Nano Developer Equipment has two M.2 Key M slots which permit set up of PCIe SSDs. You may boot the system from the SSD, bypassing the SD card. A SSD is far sooner than the default storage medium of a SD card (5-10X in follow).
Earlier Jetson manufacturing modules within the Nano/NX kind issue use eMMC for his or her principal drive storage. eMMC is a kind of flash reminiscence. The brand new Orin Nano and Orin NX forego the eMMC, and boot immediately from a SSD hooked up through a M.2 Key M slot. This brings alongside a few adjustments. First, there’s a small quantity of flash reminiscence, known as QSPI, on the Jetson module which holds the bootloader and {hardware} configuration particulars. Right here’s an article which speaks extra in depth about that. QSPI is generally used within the SD card model of the earlier era Jetson Dev Kits. QSPI is current on all Orin Nano/NX modules.
The second change is the shortage of eMMC on the manufacturing modules. With ever growing storage calls for for Deep Studying duties, many customers have been working out of reminiscence on their eMMC drives. Reasonably than providing ever bigger eMMC, NVIDIA determined to easily use an exterior SSD. eMMC is dear (and could also be tough to supply), SSD is much less so. One other benefit is that SSDs can be found in a wide range of sizes, 128GB to 1TB can be found at client costs underneath $60 presently.
Deciding on a SSD
Listed here are some issues to bear in mind when shopping for a SSD on your Jetson Orin Nano Developer Equipment. The primary is that you could use a PCIe SSD. SSDs can be found in two flavors, PCIe and SATA. Many PCs use SATA drives, so it’s important to watch out when shopping for. Sometimes SATA drives have two notches on their connector edge, whereas the PCIe drives have just one. The SATA drives no-worky on the Jetson.
The second factor to know is that the Orin Nano Devkit NVMe slot is PCIe Gen 3. Which signifies that you received’t get Gen 4 speeds if you’re utilizing a Gen 4 drive. Most Gen 4 drives are suitable with the Orin Nano, however you normally pay a premium for no additional advantage.
The third factor to know is that you must most likely know the way a lot energy the drive attracts. Within the video for instance, we’re utilizing a 1TB drive with an influence draw of two.5A at 3.3V. That is 8.25W. The Orin Nano Devkit board can present 36 watts whole to the system. Not like a conventional desktop, you should hold observe of your energy funds. Keep in mind that the Orin Nano SoC itself can use 15W (you’ll add just a little extra for a security buffer). When you add in one other 8W, which means you’ve got about one other 8-10 for different peripherals give or take. Smaller capability drives have a tendency to make use of much less energy.
Additionally, keep in mind you’re going to want backups. Proper? So a bigger drive just isn’t all the time a blessing.
Some SSD Suggestions
Right here’s a pair which have labored nicely over time. That is one space the place we’ve seen value decreases!
- Samsung 970 EVO Plus (500GB)
- Essential P3 (500GB)
- Western Digital Blue SN570 (500GB)
The drives can be found in numerous sizes, discover one that matches your wants. When you’re procuring, you might also wish to decide up a jumper to place the Jetson into pressure restoration mode. You’ll additionally want an information succesful USB-C cable to attach your Jetson to your host PC.
The Flashing Course of
NVIDIA gives alternative ways of flashing the Jetson. You could have an x86 host machine, desktop or Linux. The necessities for the distribution are completely different relying on which technique you select. One strategy to set the whole lot up is to make use of the official NVIDIA SDK Supervisor. That is the really useful approach if you’re new to the Jetson ecosystem. SDK Supervisor runs on completely different distributions and underneath Docker.
In case you are just a little extra arduous core, you may flash from the command line. I’ve written some comfort scripts to assist with this. These scripts are derived from directions immediately from the NVIDIA Jetson Linux web site and Jetson Linux Developer Information Fast Begin part.
To be clear, flashing from the command line is severe enterprise. In case you are an expert developer, you will want to be taught the completely different flashing choices. These choices should do with safety, redundancy, and flashing a number of Jetson directly. All necessary in a manufacturing atmosphere.
These scripts, then again, take the commonest use case and automates it.
The method takes ~ 45 minutes, relying in your host pc and community connection speeds. The JetsonHacks scripts present guard code across the NVIDIA equipped flashing scripts. The JetsonHacks scripts confirm that they’re working on the precise machine and that the acceptable Jetson is in restoration mode. Issues like that.
In overview, the scripts do the next:
- Obtain the Board Support Package (BSP, flashing instruments, bootloader, {hardware} definition, and so on)
- Obtain the rootfs (These are the system recordsdata that you simply normally see on a Linux system)
- Assemble the BSP and rootfs
- Copy NVIDIA person area libraries to the rootfs (apply_binaries)
- Set up conditions on the host used for flashing
- Flash the Jetson
- Updates the QSPI
- Flashes the SSD
To obtain the helper scripts and setup the flashing atmosphere:
$ git clone https://github.com/jetsonhacks/bootFromExternalStorage.git
$ cd bootFromExternalStorage
$ ./get_jetson_files.sh
Flashing the Jetson
As soon as the archives are expanded and put within the appropriate place, put the Jetson into Pressure Restoration mode. Comply with the process within the video. Ensure that the ability is off, jumper pins 9 and 10 on the button header collectively, and apply energy. With the USB-C cable hooked up to the Jetson and host, just remember to can see the Jetson utilizing the lsusb command.
You may then use the comfort script within the repository to flash the Jetson:
$ flash_jetson_external_storage.sh
It takes ~ 20 minutes to put in Jetson Linux. After flashing, the Jetson will likely be in ‘oem-config’ mode, able to be setup. At this level, we’re completed on the host facet.
Putting in JetPack
Take away the ability from the Jetson. Guarantee that the jumper pin is faraway from the button header. Join your Jetson to the Web. You may arrange the Jetson headless, or as proven within the video related to a monitor, keyboard and mouse. After going by means of the oem-config sequence, you’ll have a fundamental set up of Jetson Linux. You may then set up JetPack.
JetPack is in NVIDIA repositories, and may be put in through APT.
$ sudo apt replace
$ sudo apt improve
$ sudo apt set up nvidia-jetpack
After about 20 minutes (relying in your connection pace), the entire NVIDIA JetPack goodness will likely be put in.
Notes
- Within the video, the host is working Ubuntu 20.04
- Within the video, Jetson Linux model 35.3.1 is put in
- JetPack 5.1.1 is proven being put in on the Jetson
- Jtop is proven in use within the video
- Within the video, the SSD is unformatted earlier than flashing
