I loaded it with Linux 2.6.15 + latest omap patch. Loading the kernel shows no problem. My g_ether options is following: ------------------------------------------------------------- # USB Gadget Support # CONFIG_USB_GADGET=y # CONFIG_USB_GADGET_DEBUG_FILES is not set CONFIG_USB_GADGET_SELECTED=y # CONFIG_USB_GADGET_NET2280 is not set # CONFIG_USB_GADGET_PXA2XX is not set # CONFIG_USB_GADGET_GOKU is not set # CONFIG_USB_GADGET_LH7A40X is not set CONFIG_USB_GADGET_OMAP=y CONFIG_USB_OMAP=y # CONFIG_USB_GADGET_DUMMY_HCD is not set # CONFIG_USB_GADGET_DUALSPEED is not set # CONFIG_USB_ZERO is not set CONFIG_USB_ETH=m CONFIG_USB_ETH_RNDIS=y # CONFIG_USB_GADGETFS is not set # CONFIG_USB_FILE_STORAGE is not set # CONFIG_USB_G_SERIAL is not set --------------------------------------------------------------- When I modprobe the g_ether it shows ------------------------------------------------------------ Using /lib/modules/2.6.15-omap1/kernel/drivers/usb/gadget/g_ether.ko usb0: Ethernet Gadget, version: May Day 2005 usb0: using omap_udc, OUT ep2out-bulk IN ep1in-bulk STATUS ep3in-int usb0: MAC d2:4d:8a:2d:38:ce usb0: HOST MAC 00:dc:c8:f7:75:05 usb0: RNDIS ready otg: b_idle, SWITCH to gadget, ctrl 098021 isp1301_omap 0-002d: ready for dual-role USB ... ------------------------------------------------------------- Everything seems fine. Then I use USB cable to connect the board to another Linux box. The linux box recognize it as a ethernet device. After simple network configration, I ping the board from linux box and the board hang. Anyone have the same problem? I have try this feature with other latest Linux kernel + omap patch and they all have the same problem. Regards, Yuh-Jye
