I have built an embedded linux using buildroot. after generating
rootfs.tar file system, I have tested the embedded linux and figured out
that every change I made to the linux is not taking place after reboot.
my question is: how to enable buildroot linux to have a persistence file
system and can save changes?
I have generated: rootfs.tar , rootfs.cpio , bzImage of kernel.
any help appreciated.

Which one are you using? If you've generated a rootfs.cpio, maybe
you've enabled the initramfs option, which as its name suggest is a
filesystem in RAM, which explains why your changes disappear after a
reboot.
Use a filesystem stored on persistent storage, such as a SD card, eMMC,
NAND flash or USB key.
Best regards,
Thomas
