I would know if they is a way to add usb device capability to a OLinuXino board. Is it possible to add trough an external chip ? Sorry but i am beginner in uC world and in hardware design. i have no idea how to add this feature.
I know they is usb OTG and ethernet possibility, but i would like have a real usb device.
i have seen SAM9-L9260, SAM9-L9261 chip look old. And OLinuXino look an easier step for begining.
But i have a good experience with linux (fedo,gentoo,slackware,and suse).
So i would like have
lcd capability tought GPIO
OLinuXino look pretty good , just missing USB device.
Any suggestion / opinion are wellcome
So you want the gadget interface? If all you want is for the Olinuxino to be a USB peripheral to some external host you can do this with a simulated ethernet interface via PL-25A1 type USB transfer cables.
