Failed to restart Jetson Nano developer kit after cuda installation

[user160379]

Hello all!

I’m using jetson nano development kit for my project. I was installing cuda from the official website. I Download Installer for Linux Ubuntu 18.04 arm64-sbsa and it was installed without errors but while rebooting the jetson nano dev board shows an error message and the screen appears blank. I would like to get some help to recover all my files and solve this issue. Kindly help

This was the cuda installer
https://developer.nvidia.com/cuda-downloads?target_os=Linux&target_arch=arm64-sbsa&Compilation=Native&Distribution=Ubuntu&target_version=18.04&target_type=deb_local

Error message after restarting after the installation of Cuda

If you downloaded CUDA or other content from any source other than JetPack/SDK Manager (or the URL JetPack/SDKM points to), then you’ll probably need to reinstall. JetPack/SDKM is the only official site for Jetsons. The “official” (but general use) site is for different hardware even in the case where it is ARM architecture. The GPU those other packages are expecting is for a PCI based discrete GPU, but the GPU of a Jetson is integrated directly into the memory controller. The two drivers do not mix.

Note that JetPack/SDKM is not just for flashing. If the flash step is unchecked, and if you connect it with the USB cable while fully booted, then JetPack/SDKM will happily install just the packages without any flash. You’d simply need to be sure that the software release flashed matches the version of the JetPack/SDKM you are using. See:

I recommend just using the most recent JetPack/SDKM, and if you have an older release, then start it with this from the host PC:
sdkmanager --archivedversions

If your release is too old, then you might have to actually go to the older release SDKM.
