Ok thanks for the info, here's about, sdcard.img
I have made two partitions from buildroot, those are files
(output/image) I got from buildroot, I extracted and copied them manualy
with "cp"

What is a "sdcard.img" ? Elaboration is required.
But typically, no it wont work. Typically, you'll want to use dd,
or tar. Then the partition that is meant to be bootable, needs to
be marked as bootable using a suitable tool. Such as fdisk, or
perhaps sfdisk.
Such a workflow, would look something like this:

<https://eewiki.net/display/linuxonarm/BeagleBone+Black#BeagleBoneBlack-RootFileSystem%28smallflash%29>
Keep in mind this is Roberts build guide for the beaglebone
black, and is not intended in this context to be an exact steps
example of what you need to do. But it should give you a rough
idea of what all needs to be accomplished over all. *If* you're
familiar enough with the Linux command line, and tools used.
Additionally, if you search the internet for "debootstrap how to"
You'll probably find a lot of information on how one would create a
rootfs, from scratch, and how to apply that knowledge for this
purpose. But again, in this context, there will be a lot of
superfluous information. So you'll have to parse what you read,
understand what's going on, and take away what you need from it.
