I followed these ( Install Jetson Software with SDK Manager :: NVIDIA SDK Manager Documentation) steps for using sdk manager.
==> sdk manger in NX Dev kit
Installed succesfully in my NX dev kit , Display connected to dev kit (hdmi) showed authentication (user id , password and other settings) steps. Hence everything was perfect.
==> sdk manager in NX SoM custom carrier board.
attached SD card (with bootable image in it) + activated recovery mode + connected display + used ethernet as well ,
but installation process after 34% , get stuck in (whereas download process is completed)
even the display (connected via hdmi) is also not working.
