Hi we have our imx6ul Target board. USB OTG host mode is working fine.

But to check the USB OTG device mode, we are inserting the modules: configfs.ko, libcomposite.ko and g_mass_storage.ko.

 

While doing "insmod g_mass_storage.ko", it is giving the following errors:

g_mass_storage: Unknown symbol fsg_common_set_ops (err 0)
g_mass_storage: Unknown symbol fsg_common_set_sysfs (err 0)
g_mass_storage: Unknown symbol fsg_common_run_thread (err 0)

insmod: ERROR: could not insert module drivers/usb/gadget/legacy/g_mass_storage.ko: Unknown symbol in module

 

Please suggest something on this.
