[Gumstix-users] GPIO 34 and 39

[Chris S. <chr...@gm...>]

The robostix I/0 page says that the gumstix GPIO lines 34 and 39 are
brought out through the HiRose to the robostix.  In experimenting with
them, it seems that 34 is *only* a recieve pin and 39 is only a
transmit pin.  I can't reconfigure them through /proc/gpio/GPIO34 and
39.

It seems that there is no way to configure them as general GPIO pins.=20
This doesn't work for GPIO39.

echo GPIO in >/proc/gpio/GPIO34
echo GPIO in >/proc/gpio/GPIO39

Is this the case?  I need two GPIO input ports on the gumstix/robostix
combination.
