Hi everyone, Nano will continue to be supported with updates to JetPack 4.6 - please refer to Jetson Software Roadmap for 2H-2021 and 2022 for more info. The latest update was released earlier this month (JetPack 4.6.3/L4T 32.7.3 released). JetPack 5 is for Xavier and Orin only and there aren’t plans to backport it to Nano/TX1/TX2.
Nano 4GB wasn’t EOL and thanks for your patience while it was out of stock due to supply-chain issues (for EOL announcements see the Jetson Product Lifecycle page). Please direct further questions to the Nano forum where they will be more visible to the Jetson team so that we can reply in a more timely manner.
