ELDK for Armv8.2

ELDK for Armv8.2

[Ron Eggler]

Hi,

I'm working on a BSP that features the Reesas RZ/G2L & RZ/V2L CPUs which
have a Cortex-A55 core onthe  Arm8.2 architecture. I don't see it listed
under https://www.denx.de/wiki/view/ELDK-5/WebHome#Section_1.4. and was
wondering if there's a way to use ELDK for this Aarch64 architecture at all?

Thanks,
Ron

I would recommend you use Buildroot <https://buildroot.org/> to build a
cross compiler and pretty much everything else you need to boot and run
linux (or your custom code) on your CPU. It takes a bit to configure it and
a while to build from scratch, but it works very well. Buildroot makes
building a cross compiler extremely simple. Building a whole (linux based)
system is complicated only because there are many, many choices to make -
the actual building is trivial.

Oh, and if you are only looking for an ARM cross compiler,
Debian/Ubuntu/variants have an apt package for that which includes all the
libraries and binutils etc.
(RedHat flavors probably do too)

Instead of Buildroot, I have now built a distribution that I can use on the
platform with Yocto and it does give me U-Boot as well as an SDK with it as
well.

Thanks!
