Flashing the SD card is different than flashing the Jetson. The SD card is only the operating system, while the module itself has QSPI memory which contains the equivalent of a BIOS (in software only) and bootloader (it is a custom boot chain). The Jetson itself must be flashed when it is a dev kit with an SD card (but the Jetson itself only needs to be flashed once with a compatible major release version, and then you can install any number of SD card releases on it so long as they are the same major version).
There are 4 usb connections on the front and 1 micro usb. Please be more clear as to which one I need to connect to. Tell me step by step what you want me to do, and I will. I am getting frustrated with this thing already as it worked for a while, then not.
mentioned here. J28 micro usb port is the flash port.
It looks like your board is not powered on in this setup.
Please power on the board by using power barrel instead of of USB port because your USB port needs to be used by flash.
Put a jumper on J48 to make the board get power from power jack.
I just checked the whole photos you shared of this board.
Actually that carrier board is not a NV devkit. Thus, what @linuxdev and I shared are not applicable to that board.
In brief, the carrier board you are using is made from some other unknown vendors.
Is there any power LED on that board to indicate your board is powered on?
Just to clarify. When you connect micro usb port to host, if your board could power on, then we don’t need you to try power barrel. However, if it does not, then you need to get power barrel work.
Yes, when I plug in the power barrel I get a led light. But my sdk manager still does not see the board.
Do you see any new log in your host PC’s “dmesg” command when you plug in the usb cable from Jetson to host?
Also, could you clearly take a photo of what is the exact pin you put the jumper on your board?
Your host PC could only detect your Jetson when it is in recovery mode and you have to use micro usb connected.
Please be aware that your photos didn’t show that thing at all. We only saw a wire is there.
I don’t want to say it must be such mistakes but we did see some users put the jumper in the wrong pin before…
I don’t see how you really connect things after you changed to use power barrel. Show that photos as well.
If:
- The Jetson is unpowered;
- The jumper for recovery is shorted;
- And you have USB connected;
- You now monitor the host PC with “
dmesg --follow”…
Do you see any log from the “dmesg --follow” if you now add power to the Jetson?
None of the developer kits come with a battery backup. Can you say where this was purchased? If we can figure that out, then the information for flash will likely come from that vendor (and the firmware/device tree would also differ; perhaps a patch to NVIDIA’s flash software, or perhaps their own flash software).
I ordered it from Amazon. The seller was WayponDev according to Amazon.
Could you take a photo of all the things connected together when you attempted to flash your board?
I assume power barrel/micro usb cable/ jumper should all be connected there.
What is your method to run sdkmanager on a Windows machine?
That could be the problem that your Jetson is not able to get detected…
I downloaded the app from NVIDIA for Windows.
Please check this table from sdkmanager tool page.
Windows machine is not able to install Jetpack… so please move to a native Ubuntu 18.04 host.
Ok this is on the Ubuntu side. It shows to see a Jetson but doesn’t give any sdk pack options I can click on.
Tried the archived version but then it doesn’t see the board again.
