I updated the CUDA tools on the NVIDIA JETSON TX2 4GB module that I’m using. Then, when I reboot the system, although the power light of the device is ON, there is no signal from the HDMI interface to the display screen, so I can’t connect the device to the screen. What should I do about it? (No problem with HDMI cable)
You will want to get a serial console boot log. See:

Assuming your device runs on an SD card (a dev kit, versus an eMMC model on third party carrier board), then you might plug the SD card in to a host PC and check to see if it ran out of space.
Hi,
The CUDA version has to fit Jetpack version. It is not suggested upgrade only CUDA but leave other packages in old release versions. Suggest install the SDK Components through SDKManager.
Thank for reply. How can I install SDK components? Currently I can’t turn on the display from the HDMI interface. Can I connect the device to the host computer via the serial port and install the SDK?
Hi,
You can connect the developer kit to host PC(in Ubuntu 16.04 or 18.04) through type-A t micro-B adapter. Connect type-A port on host to micro-B port on developer kit. Please follow the steps:
- Install SDKManager on host PC
- Press and hold recovery button on developer kit. In the meantime press reset button to let TX2 enter recovery mode
- Re-flash the system image and then install SDK Components through SDKManager
Hi DaneLLL
I did these operations. The HDMI port is working good, but the USB ports are still faulty and not read the USB connections. Why might this be caused? Which version should I use for JETPACK?
Please use the JetPack 4.6.3 which is the latest version for TX2.
I’m using JETPACK 4.6.3. I installed the UBUNTU 18 operating system, but I cannot proceed because the USB interface connection not working. What could be the reason for the USB interface not working?
Hi,
For the USB interface connection not working, which step do you get stuck:
- Install SDKManager on host PC
- Press and hold recovery button on developer kit. In the meantime press reset button to let TX2 enter recovery mode
- Re-flash the system image and then install SDK Components through SDKManager
TX2 cannot enter recovery mode in step 2?
Hi, DaneLLL
I installed SDKManager on the computer with Ubuntu 18 operating system. Then I kept the recovery button pressed and started the Jetson TX2 module and pressed the reset button and released it. SDKManager detected the TX2 device and started to install. Then I came across the figure 5 in the step 3 in the attached link and I opened the Jetson TX2 module for Ubuntu installation, but when I connected the keyboard and mouse to the device via the USB interface, the TX2 module did not read USB connection and I coulnd’t continue.
Hi,
The board may be physically broken in HDMI part. Please try this to create a default set of user/password, flash the system, and then see if you can boot to Ubuntu:

Thnak for reply.
Do I need to connect from the debug interface to do these operations?
Do you have any comment on this error?
Hi,
Could you try Jetpack 4.6 or 4.5.1? If it happens on different software releases, the board should be physically broken.
