NVIDIA Jetson Linux 35.6.0 flash failed -- boot/extlinux/extlinux.conf is not found

I wouldn’t use SDK Manager. As I said I don’t have a specific computer to run SDK manager. And I’m quite sure it would not take that much resource to install only a system.

I perfer to use following command line sequence:

$ sudo tar xvf jetson_linux_r35.6.0_aarch64.tbz2
$ sudo tar xvpf tegra_linux_sample-root-filesystem_r35.6.0_aarch64.tbz2 -C Linux_for_Tegra/rootfs/
$ sudo ./apply_binaries.sh
$ sudo ./nvautoflash.sh 

Do you mean the above sequence has trouble to use nvautoflash.sh ?
