Can we flash the zImage only?

when we want to flash the zImage.
we will use the command :sudo ./flash.sh -S 14580MiB jetson-tk1 mmcblk0p1

but the command will flash the system.img too .so it will takes us a long time to wait for it .

so I want to know is any command for us to flash the zImage only.

Thank you very much.

Kernels were only flashed back when fastboot was used. All of the current L4T uses u-boot…flash is for entire partitions, kernel update is a mere file copy (with a possible alternate name) to “/boot” and optional edit of extlinux.conf.

so when we use the L4T,we can’t flash the zImage by flash?

Thank you for your reply.

There is no need to flash. U-boot reads regular files on an ext4 file system. Fastboot did not understand ext4 or any file system, thus it had to be flashed as binary data. U-boot reads “/boot/extlinux/extlinux.conf”, and looks for files pointed at by the configuration key/value pairs. No flash required.

NOTE: Simple copy via scp or sftp is a nice way to transfer a zImage.

I got it .

Thank you very much.
