we bought an NVIDIA Jetson TX2 and just tried to power it up and test everything.
We connected every cable according to the manua.
After plugging in the power connector and pressing in the PWR-button on the Jetson the following lights went on:
CR1 and CR2: green, CR5 and CR6: red.
We are receiving no signal on our HDMI monitor and also the USB-periphery is not showing any signs (on the keyboard, all lights are off).
We tried different periphery and different monitors. Also every periphery and monitor we tested worked on a Raspberry Pi.
Can you help us?
The lights are normal.
If you are using a module which was not in a developer kit (meaning it didn’t arrive with a carrier board), then this is an empty module needing flash.
If this is a dev kit, then it isn’t uncommon for HDMI issues to not show on the GUI, but still have the unit otherwise correctly booted.
If you have the unit connected to a router, then you might try to ping its address or ssh in.
The best method to know what is going on is to use serial console. See:
Even if the GUI fails it might be possible to get to a text console via CTRL-ALT-F2.
We do have a developer kit, so there must be an OS already installed.
We have the Jetson connected to a network and were unable to find the IP adresse and therefor were unable to connect with SSH.
Because the keyboard is not working, we can not open a text console.
we tried to read the serial data with the serial monitor from our arduino uno. Here it is:

Okay thank you.
We will test this in the next days and then reply back here.
You were right.
Flashing the Jetson solved the problem. Thank you!
