I need some help getting this thing to power up. I am on my third Nano with none of them illuminating a single pixel! The first two were RMA 'ed and I am afraid the third one is junk as well.
I am using the the Adafruit 5V4A power supply recommended and have set the jumper J48 to the correct position. I get nothing. The green power LED is illuminated, but that’s it. USB keyboard mouse or not, no difference. I have an ONN 128GB microSD card installed and have formatted it as exFAT and just straight dd dump of the image to card. No difference.
How would I connect a serial port? From the documentation, when J48 is set to take power from the barrel jack, the mini USB port should function as a serial console, but I get no data from the port. The system it is connected to does not see a USB device connect/disconnect. So how are you supposed to get serial data. Please do not send me links for the older style board, with a single camera port; mine has 2 and no serial port header located near the camera port.
In brief, please try sdkmanager and dump serial log. Also, I am not sure what link did you see… the serial log is not from the usb port but from specific pin.
Fellow Noob here. I spent a while scratching my head over what looked like a dead board too. Green LED but nothing else.
I had downloaded an SD card image from the site and DD’ed the image onto an SD card. Powered up. Nothing. About to send it back.
I don’t know what possessed me, but I decided to try the SDKManager / recovery mode technique and to my surprise it worked.
Here’s my rough step by step. Maybe it can get you going. It’s a really nice board. Worth the effort.
download sdkmanager
run sdkmanager
select the right board (presuming Nano w/Dev Kit)
let it do its downloading
then it will put together a set of images for a set of partitions for the SD card
it will ask if it can flash your board.
power from the DC jack (or GPIO pins)
power jumper on
put Force Recovery jumper on pins 3 & 4 under the module
power up
remove Force Recovery jumper
connect host to micro USB port
confirm NVIDIA usb device (lsusb)
you say yes to the sdkmanager flashing your board
15mins of flashing happens
at the end CONSOLE ON SCREEN, followed shortly after by glorious Ubuntu setup
sdkmanager will want to continue downloading all the lovely CUDA etc. stuff. You can say yes or no to that.
That method of download can be accessed from inside the SDKManager install (see ~/nvidia…) as flash.sh. One problem is that the resulting sd setup can’t get bigger than 16G without more fiddling.
I’m now 3 days into my Nano experience. Happily remembering how to build the kernel!
Your suggestions led me to the resolution. And am posting from the jetson nano!!! One thing to note, on the B01 boards, it is jumper J50 and pins 9 and 10 … from the user guide.
• [J50] Carrier Board Rev B01 only: 12-pin button header; brings out system power,
reset, UART console, and force recovery related signals:
• Pin 1 connects to LED Cathode to indicate System Sleep/Wake (Off when system
is in sleep mode).
• Pin 2 connects to LED Anode.
• Pins 3 and 4 are respectively UART Receive and Send.
• Pins 5 and 6 disable auto power-on if connected.
• Pins 7 and 8 reset the system if connected when the system is running.
• Pins 9 and 10 put the developer kit into Force Recovery Mode if they are
connected when it is powered on.
• Pins 11 and 12 initiate power-on when connected if auto power-on is disabled.
