P9_14 pinmux file not found! on BB Green but not Black

On the Black I run:

bone$ config-pin -q P9_14
P9_14 Mode: gpio Direction: out Value: 1

But on the BB Green Wireless I get:

bone$ config-pin -q P9_14
P9_14 pinmux file not found!
Pin has no cape: P9_14

What’s the difference here? How do I get the pin mux to work the same on the Green and Black?

please run:

sudo /opt/scripts/tools/version.sh


It was an old boot loader. I posted a fix[1].
