How to download Jetpack 4.3

I am trying to install the 121-IMU/MCU carrier board firmware for a Jetson TX2 module. My issue, the download instructions for the firmware require JetPack 4.3 (L4T 32.3.1). After downloading the SDK manager, there is no option for Jetpack 4.3.

Hi lostlonkey5,

Please run below command to download JetPack-4.3:

$ sdkmanager --archivedversions
