6.12 is the latest LTS supported by evl, so yes, this may be a good
choice in your case. The grub installation issues you are seeing are not
related to evl which has no influence on the aspects you mentioned, you
would have the same with a plain stock linux kernel. You may want to
refer to other online resources explaining how to build and install a
mainline kernel in place of the one shipped by your linux
distro.

In the early stage of bringing up your target system, you may want to
disable CONFIG_EVL, CONFIG_DOVETAIL and CONFIG_IRQ_PIPELINE options in
your Kconfig, until you get a v6.12 kernel properly booting your box, in
order to rule out any issue with evl.

Once this kernel boots with a working console in order to get the
information you need to progress, then you could enable these options
back one by one in reverse order, discussing on this mailing list any
issue observed while doing so.
