Thanks Emmanuel!
I ran: make=C2=A0 -j4 buildkernel KERNCONF=3DPPSGENERIC
Then installed with: make installkernel KERNCONF=3DPPSGENERIC
The sun50i-a64-pine64.dts has the modification already suggested:
/* On Pi-2 connector */
&uart2 {
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 pinctrl-names =3D "default";
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 pinctrl-0 =3D <&uart2_pins>;
=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0=C2=A0 status =3D "okay";
};
Running: ls -l /boot/dtb/allwinner/

The dtb files have been created and installed by the 'installkernel'=20
command.
Unfortunately though nothing shows up in dmesg or /dev again outside of=20
the standard uart0?
dmesg |grep uart
uart0: <16750 or compatible> mem 0x1c28000-0x1c283ff irq 23 on simplebus0
uart0: console (115384,n,8,1)
Is there an additional step which needs to be done to get this to work?
Regards,
Kaya
