I'm building a custom image-qt5 using yocto tools. Once the build terminates, there is a file named qt5-image-raspberrypi2.tar.xz in the folder ...build/tmp/deploy/images/raspberrepy2/.

How can we write to sdcard for the raspberrypi?

Your question is a bit vague.

If you were just looking at writing the qt5-image-raspberrypi2.tar.xz file to your SD card; you can use the command: dd to achieve this. Given that it is a tar ball you will need to first handle this before writing it to the sd card.

Example (where /dev/sdX is your mounted SD card on your computer): 

tar -xzOf qt5-image-raspberrypi2.tar.xz | dd of=/dev/sdX bs=1M

If you already have an sdcard image that has been generated within Yocto and you wish to include the qt5-image-raspberrypi2.tar.xz tar ball to the sdcard image, then you will need to modify your recipe to add the file to your SRC_URI list.

Example: 

SRC_URI += '$(DEPLOY_DIR}/qt5-image-raspberrypi2.tar.xz'

Replace the tar ball file name with appropriate variables which are used when generating the name, or you could hard code it, as above.
