Compile linux with Buildroot [odroidXU4 batocera gamming station + some packages]

Hey, I need help on selecting the right options when building Batocera. It is a linux image that flashes into a small boards like a raspberry, but im using an OdroidXU4 (hardkarnel).

My issue is to find the target architecture and the packages needed to compile.

Batocera contains lots of utilities like emulators, kodi tv, samba, torrent clients, etc which is pretty handy.

list: https://github.com/batocera-linux/ba...master/package

By default Batocera includes all I need but ctorrent package.

Following the instructions on the gh readme I do:

Code:$ make menuconfigAfter that Im quite lost and I don't know what options do I have to select.

Target options?
Build options?
etc

For instance on "target options":

Code: a" a" Target Architecture (ARM (big endian)) ---> a" a"
a" a" Target Binary Format (ELF) ---> a" a"
a" a" Target Architecture Variant (cortex-A7) ---> a" a"
a" a" Target ABI (EABIhf) ---> a" a"
a" a" Floating point strategy (VFPv4-D16) ---> a" a"
a" a" ARM instruction set (ARM) --->no clues xd

Thanks!
