Hey Denys,

Wow, I wasn't expecting support to be dropped.  I'm sure there is still a
bunch of people using it.  I guess I could maybe maintain it if someone
would give pointers on how to go about it.

OK, so how about this ... I use the same u-boot and kernel that I'm
currently using (but built with the same toolchain to build the rootfs ...
meta-toolchain) but use am180x-evm to build the rootfs & packages of other
stuff I need?  I mainly need to have the packages kept relatively up to
date (security patches etc.).

Do you see anything wrong with that approach?  Same ABI right?

Regards,

Brian
