Sorry for the delay in replying, I'm off sick atm, and not really checking
work email.

Which UART are you connected to?

Fairly recently ATF, U-Boot and the Linux kernel all switched to a UART
on the low speed connector by default. I wonder if you are still connected
to
the UART exposed on J16 where you have to solder on the connector?

The UARTs on the low speed connector can be easily accessed with
this daughter board https://www.96boards.org/products/mezzanine/uarts/

It is useful to have both connected, as depending on what versions of ATF,
U-Boot and kernel you use, you may get output on both UARTS, and things
will appear to not work.

Last version I tested was 2015.10 with the latest versions of ATF at that
point. I will try and test latest version of U-Boot and ATF at some point
when I return beginning of March.
