I'm currently using gbridge / tcpip with the IID1-simple-gpio-module.mnfs example to hook up a fake module that just responds to socket I/O.
A couple of small changes were required, but everything seems to be parsed, bundles, cports are all created.
However, for some reason, greybus does not seem to automatically bind the device to the gb-gpio driver, nor does it probe the device. I only see pings after the svc has inserted my fake module and handshake is complete.
Is anyone aware if a separate step that is required to bind the device to the driver? I've tried
sudo sh -c 'echo -n 1-2.2.1 > /sys/bus/gbphy/drivers/gpio/bind'
but that gives me -ENODEV
It should "just work" if the manifest signatures match the what the greybus gpio driver expects.
Do you get any logging messages in your kernel log when you do this?
