Hi Team,

I using 8 GB SD card for flashing .wic image with expand-on-first-boot 
added in  */conf/machine/imx6ull-14x14-evk.conf file .*
*It gets expand up to 6.5 GB*
 Is there any where we can change manually the size how much *like 5 GB or 
4 GB* after flashing it to SD Card in ISAR 
please suggest us for that without expand-on-first-boot , is there any way 
we can alter the SD card size manually and build  in ISAR

expand-on-first-boot is designed to expand the *last* partition to the
available maximum. If you want a fixed size you can modify your
partition layout (.wic file) accordingly.

^^ This doesn't make sense on a public mailing list...

Right, i.e. --fixed-size 4G or --size 4G

see https://docs.yoctoproject.org/ref-manual/kickstart.html

And you want to not install expand-on-first-boot in that case, or add
another last partition to become the subject of growing.

That whole on first boot growing is meant for cases where one does not
know how big the storage medium is going to be and use all of it. If
you know how big it is going to be, or if you do not need the space ...
it is likely better to avoid such dynamic resizing.
