How to copy zImage and imx7d-sdb.dtb files into sd card

We are interesting the model, and will purchase it:

MCIMX7SABRE: SABRE Board for Smart Devices Based on the i.MX 7Dual Applications Processors


I see the system is boot up from the sd card.

Now I recompile the source codes and have new zImage and imx7d-sdb.dtb files.  Can I just copy over the SD card by following steps, and will it replace with a new kernel image ?


# mkdir /media/boot

# mount /dev/sde1 /media/boot

# cp zImage /media/boot

# cp x.dtb /media/boot


Please tell me what to do to with a new zImage and imx7d-sdb.dtb files?

Do I need to flash the SD card? And how?


Thank you so much.
