how can we update kernel image?we think as follows:

1、there are two zImage patitions on emmc,one is old version and another is new version.

2、download the new kernel version and save in a partion,then uboot guide one of the two zImage to start

3、if succeed,update succeed,else the uboot will guide another zImage

Is it right?

You can use the TFTP to update the zImage and file system.

FTP service will be used to transfer the kernel image from host to target every time the system reboots.
