There is a faster way to install the system environment required by the l4t API,?and to compile and run the examp1 quickly
4:does any help for this issue with intsall Jetpack 4.3?
Please help,thanks

Hi Rico,

The JetPack SDK is the most comprehensive solution for building AI applications. Use NVIDIA SDK Manager to flash your Jetson developer kit with the latest OS image, install developer tools for both host computer and developer kit, and install the libraries and APIs, samples, and documentation needed to jumpstart your development environment.
See https://docs.nvidia.com/sdk-manager/install-with-sdkm-jetson/index.html

thanks Kay,we will try this first

Hi Rico, to enable all 8 CPU cores, you need to change your nvpmodel power profile to 0 (MAX-N) or 3 (30W_8CORE). You can run this command to change it to MAX-N:

sudo nvpmodel -m 0

See here for a table of the built-in power profiles for Jetson AGX Xavier:
