This is to inform you that, I have purchased Jetson Nano module along with carrier board and heat sink combo from Rarecomponents (https://rarecomponents.com) of Rs.20,461/- (Copy of Bill attached herewith) on 20 April 2022.
After receiving the device, We tried to boot the device under the guidance of experts in the similar fields, but its not responding ( Screenshots of during booting attached herewith)
I spoke to the rarecomponents representative and he said that he will replace the components only when you approve my request
so, it is my humble request to you kindly go through my request and do the needful on an urgent basis.
There are different models, and instructions to flash differ between models. Flash is quite often mandatory for first boot. Jetsons do have modules which are either an eMMC version (built in storage) or an SD card version (root filesystem on SD card and no eMMC, but the module has QSPI memory used in boot). The first thing is to identify which model you have.
Is there a URL you can post to the exact model you have? If it is a developer kit, then it is easy to support here. If it has a custom carrier board, then it has to use the board support package software designed for that carrier board to flash it.
Most every carrier board will make available a serial console. Usually a 3.3V TTL logic level serial UART set to 115200 8N1, or else using a built-in micro-B USB cable (many Nano models have a micro-B USB connector for popwer, but use separate discrete pins for the UART; some models do have a serial UART simply with the micro-B USB cable). You won’t necessarily need this if flashing is all that is required, but if any kind of diagnosis is required, or if you plan to do any development, then you’ll want serial console access. Knowing which model will help to identify which flash software to use and which serial console cable type to use.
An eMMC module will always need a third party carrier board. It’ll be important to know what carrier board it is, and most likely what software support the manufacturer of the carrier board provides. If that carrier board is an exact lane routing match to the development kit carrier board, then the ordinary NVIDIA flash software would be sufficient, but most of the time the manufacturer will provide its own board support package (which would be a different device tree, but otherwise a near match to the developer kit software). So an exact carrier board model number would be very useful.
It looks like a developer kit carrier board, but I couldn’t say from the picture. If you have a URL which actually states what model the carrier board is it would help. It might work with ordinary Jetson developer kit software, but I can’t confirm. Whatever web site URL you might be able to provide for an exact ID of the carrier board would help.
The content visible from the attempt to boot does not mean a lot, but if it is going to recovery mode just from powering up, then it probably means this has never been flashed before and a simple flash with the right software would solve the problem. I just don’t know what the right software is without knowing exact details of the carrier board.
What is the carrier board model? Is there a web page which shows the exact product, including specification of the carrier board? The module is standard and easy to deal with, the carrier board is the other half of knowing what to flash. If it is a development kit, then it is easy to work with, but if anything is different for the carrier board, then the flash has to change.
Although this is not a dev kit it looks like the carrier board is possibly pin compatible. I did not see any links to special software, but I think you’d have to be a customer to see that content. Most likely you can just flash it with the dev kit software, and if it doesn’t work correctly, no harm.
The eMMC module always ships unflashed, and so it makes sense that all you need to do is flash. You would use the most recent JetPack/SDK Manager in the 4.x release: https://developer.nvidia.com/embedded/jetpack-archive
For reference, JetPack/SDKM is flash software you run on an Ubuntu 18.04 host PC. L4T is just Ubuntu plus NVIDIA drivers. A version of L4T is what actually gets installed, and is tied to a particular release of JetPack/SDKM. The Nano should use an R32.x L4T release, and thus a JetPack 4.x.
If you get a 5.x release you could start it with: sdkmanager --archivedversions
(the “--archivedversions” causes older releases to be visible; L4T R34.x is only available with JetPack 5.x, and so to see L4T R32.x from JetPack 5.x you’d have to start it with that option)
If for some reason that does not work with your carrier board, then you can probably flash on command line. Avoid using a VM on the host PC.
