Installation
- configure your Linux kernel:
$ make linux26-menuconfig
Device Drivers --->
[*] USB support --->
<M> USB Gadget Support --->
- and activate all USB Gadget drivers you need:
- save your configuration and then rebuild your kernel image:
$ make
now you should have the following drivers in your kernel source tree:
/lib/modules/`uname -r`/kernel/drivers/usb/gadget/gadgetfs.ko For test /lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_ether.ko Ethernet emulation on USB /lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_file_storage.ko Mass storage /lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_serial.ko Serial emulation on USB /lib/modules/`uname -r`/kernel/drivers/usb/gadget/g_zero.ko For test /lib/modules/`uname -r`/kernel/drivers/usb/gadget/imx_udc.ko i.MXL USB device Core Controller
- reflash your RootFS or manually copy imx_udc.ko, g_file_storage.ko & g_serial.ko to your target in /lib/modules/...
Usage
First, load the core controller driver on your board:
# modprobe imx_udc usb: imx_udc version: 0.5
