Message: 79427   




i 'm using bf533-ezkit,i want to use isp1362(usb controller),i choose the usb surport option and isp1362 as the host controller when i comile the image,the boot information display


"driver isp1362-hcd, 2005-04-04                                                       

bfin-wdt: initialized: timeout=20 sec (nowayout=0) "




and then i used "lsusb" to display something ,but there be nothing.I think whether is my isp1362 addresss(in my board the isp1362 addr is 0x20330000) is dirrent with the compiled driver,because my "ezkit" board is not the real ezkit board,so should i need to chang the driver or there is some other problems?




thank you for you repy!

Message: 79428    You need to add struct platform_device isp1362_hcd_device to


static struct platform_device *ezkit_devices[]


as a reference take a look at:

thank you Michael,i have followed you instruction and add  the "struct resouce" like this :






static struct resource isp1362_hcd_resources[] = {


        .start = 0x20330000,

        .end = 0x20330000,

        .flags = IORESOURCE_MEM,

    }, {

        .start = 0x20330002,

        .end = 0x20330002,

        .flags = IORESOURCE_MEM,

    }, {

        .start = CONFIG_USB_ISP1362_BFIN_GPIO_IRQ,

        .end = CONFIG_USB_ISP1362_BFIN_GPIO_IRQ,







but the last item about IRQ is the problem when i make it ,i don't know how to config the IRQ when i "make menuconfig",i can't find relative option about IRQ ,please give some instructions, thank you  again!

thank you Mike.My ISP1362 have work.Actually i connect it with a WebCam, i have compiled  ISP1362 HCD and V4L2 driver,and i inserted my WebCam ,it show some message :


root:/> usb 1-2: new full speed USB device using isp1362-hcd and address 2     

usb 1-2: configuration #1 chosen from 1 choice                                 

usb 1-2: New USB device found, idVendor=04fc, idProduct=2700                   

usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0              

usb 1-2: Product: USB2.0 WebCam                                                

usb 1-2: Manufacturer: WebCam Co Ltd   




it can instruct  that the USB driver and V4L2 have work ,but int the /dev it was no video0,so i  "mknod  /dev/video0  c 81 0" ,but in my application it can't open the devices,the  error was " No such device or address ",what can the problem was?


is the driver not really work?

Did you enable the V4L USB drivers suitable to your camera?

i have seen this doc many times  :), i don't know weather it suitable. but i inserted my WebCam  in my PC linux(2.6.28), the 2.6.28 kernel  have  integate the UVC driver,and my WebCam is UVC ,it can work perfect when i run luvcview application. so it can instruct my WebCam is  a standard UVC video class? it should work in my uclinux, i think there will be another problem. please give some help.
