Hello All,

I want to explore gadgetfs for file trasnfer, i have googled so many links but I am not clear about the exact procedure to follow.

All examples states, run usb.c, but how to make an executable for my target board (iMX6 SabreSD).

Also the controllers stated in autoconfig() functions doesnt match with the one used in SabreSD.

If i follow the procedure
1) mkdir /dev/gadget
2) modprobe gadgetfs
3) mount -t gadgetfs none /dev/gadget

I get an error "nop ci_hdrc.0: failed to start (null): -120"

If anybody can guide with step by step procedure, I would be thankful

Thanks and Regards

So, if the hardware/controllers don't match, then you will have to modify them, won't you??? If the devices aren't configured correctly, why would you think it would work?
Please don't ask us to post the how-to guides for a product...you can find them on their website, and by reading their documentation. Also, if you had just tried putting that EXACT error message into Google, you would have found something from the SabreSD site that deals with this:

You don't say what version/distro of Linux you're using, what the "many links" you've looked at are, what you've done/tried, what you're trying to connect, or give us much in the way of details at all.
