您好,我现在2410开发板上做USB gadget.在加载s3c2410_udc.ko后有如下信息: 0.00 USB: s3c2410_udc: version 07 Apr 2005 0.01 USB: s3c2410_udc_probe 0.02 USB: udc_disable called Unable to handle kernel paging request at virtual address f0a00140 pgd = c25b0000 [f0a00140] *pgd=00000000 Internal error: Oops: 805 经过查找发现是由disable_udc函数引起.现在不知道怎么解决.能不能发一份s3c2410_udc.c 和s3c2410_udc.h给我吗.trtzrdb at 163.com 谢谢!

你好!现在正在做2440开发板在LINUX下模拟成U盘作为从设备与PC机通信,也就是USB gadget驱动 通过2.6内核下2410_udc.c,file_storage.c得到加载的驱动模块 板子启动系统后: [root@FriendlyARM udc]# insmod s3c2410_udc.ko s3c2410_udc: version 28 Aug 2005 0.00 USB: s3c2410_udc_probe 0.01 USB: udc_disable called [root@FriendlyARM udc]# insmod g_file_storage.ko file=/dev/scsi/host0/bus0/target0/lun0/part1 stall=0 removable=1 0.02 USB: usb_gadget_register_driver() 'g_file_storage' 0.03 USB: binding gadget driver 'g_file_storage' 0.04 USB: s3c2410_set_selfpo
