Zynq-7000 - Errors when running PS USB Peripheral Driver Examples in (Xilinx Answer 58277)


I am following the steps in (Xilinx Answer 58277) to run PS USB Peripheral Driver Examples in OSL 2014.2.
However, I am receiving the following errors:
root@zynq:/mnt# insmod g_mass_storage.ko file=/tmp/my_file
g_mass_storage: Unknown symbol fsg_common_set_ops (err 0)
g_mass_storage: Unknown symbol fsg_common_set_sysfs (err 0)

insmod: can't insert 'g_mass_storage.ko': unknown symbol in module, or unknown parameter


The example in (Xilinx Answer 58277) was running on an older kernel version.

For later branch kernels, (for example xilinx-v2014.2) some .ko files should be inserted first.

Refer to below wiki link for more information on the Zynq Linux USB Device Driver.



Below are the required commands for the USB examples for mass storage and Ethernet in OSL 2014.2.

Mass storage:

insmod configfs.ko

dd if=/dev/zero of=/tmp/my_file bs=1024 count=4096
insmod /mnt/g_mass_storage.ko file=/tmp/my_file
insmod configfs.ko

insmod libcomposite.ko
insmod u_ether.ko
insmod usb_f_ss_lb.ko
insmod usb_f_ecm.ko
insmod usb_f_ecm_subset.ko
