Hello Alern San, Thank you so much for your reply, I will make sure that I forward these questions to linux-usb mailing list (CC'ed). I successfully cross complied usb.c on my Ubuntu machine, also I changed my controller to the SabreSD specific (ci_hdrc_imx), after executing it on target, it gave me following output : ---------------------------------------------------------------------------------------------------------------------------------------------- gadgetfs: bound to ci_hdrc_imx driver /dev/gadget/ci_hdrc_imx ep0 configured serial="xce5r4f5wv60w958rm8yqv71ur7bk6nwmvoy87o7q0gimixl55lck514kbtj0bv" ---------------------------------------------------------------------------------------------------------------------------------------------- Thank you for your guidance, I am exploring it more for image transfer. In case of any further question I will post it to you with linux-usb CC'ed. Thanks and Regards Ashwin Deshpande ________________________________________ From: Alan Stern [stern@xxxxxxxxxxxxxxxxxxx] Sent: 04 February 2015 23:16 To: Ashwin A Deshpande Cc: USB list Subject: Re: USB Gadgetfs On -1 xxx -1 ashwin.deshpande@xxxxxxxxx wrote: > Hello Alern San, > > This is with reference to http://libusb.6.n5.nabble.com/How-to-send-receive-data-using-gadgetfs-bulk-endpoint-td5076584.html Questions like this should be sent to the linux-usb mailing list (CC'ed). > I am trying to configure freescale's iMX6 SabreSD board as device and > UBUNTU Desktop as a host and transfer images over USB using gadgetfs, > 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). Compile usb.c. Or cross-compile it on a different computer, if you don't have a compiler that runs on the SabreSD. > Also the controllers stated in autoconfig() functions doesn't match > with the one used in SabreSD. I don't think that matters very much, so long as your controller provides the necessary endpoints. > 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" Somebody who is more familiar with the ci_hdrc driver will have to answer this. > If you can guide with step by step procedure, I would be thankful > > Thanks and Regards > Ashwin Deshpande Alan Stern ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Disclaimer~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Information contained and transmitted by this e-mail is confidential and proprietary to IGATE and its affiliates and is intended for use only by the recipient.
