But I found it's different from the reference design that xilinx provided for edk8.1i. So which design should I choose? In datasheet of opb_epc, I found that we should add the irq manually. So I added the irq and reset according to xapp925. After that, I patched my linux kernel using the patch by Peter Korsgaard. But when I pluged in the usb camera, it can't probe it. What should I do additionally? 2) I can't find where to initialize the base registers and irq in the usb driver for cy7c67300 provided by Peter Korsgaard. In the function usb_c67x00_drv_probe, I found it called platform_get_resource(pdev, IORESOURCE_MEM, 0). So I think I should add some register codes for usb like uartlite or temac in virtex.c. I added the following codes: #ifdef XPAR_USB_0_BASEADDR [VIRTEX_USB_0] = { .name = "xilix_usb", .id = 0, .num_resource = 2, .resource = (struct resource[]) { { .start = XPAR_USB_0_BASEADDR, .end = XPAR_USB_0_HIGHADDR, .flags = IORESOURCE_MEM, }, { .start = XPAR_INTC_0_USB_0_VEC_ID, .end = XPAR_INTC_0_USB_0_VEC_ID, .flags = IORESOURCE_IRQ, } } }, #endif and define the following macro in xparameters_ml403.h. #define XPAR_INTC_0_USB_0_VEC_ID XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR #define XPAR_USB_0_BASEADDR XPAR_CYPRESS_USB_PRH0_BASEADDR #define XPAR_USB_0_HIGHADDR XPAR_CYPRESS_USB_PRH0_HIGHADDR After that, it still can't prob the usb device. So could you give me some suggestion about making usb work on ml403? Thank you very much!

Hi First of all, I'm a beginner, so my = questions may be funny .... sorry for that.

Any how your ideas are very valuable for me. = I'm going to have the usb work on ML403.

I have two questions about the usb on ml403 = board.

1) In EDK9.1i, we can use the wizard to build = a new design with usb. But I found it's different from the reference design = that xilinx provided for edk8.1i. So which design should I choose? In = datasheet of opb_epc, I found that we should add the irq manually. So I added the irq = and reset according to xapp925. After that, I patched my linux kernel using = the patch by Peter Korsgaard. But when I pluged in the usb camera, it can't = probe it. What should I do additionally?

2) I can't find where to initialize the base registers and irq in the usb driver for cy7c67300 provided by Peter Korsgaard. In the function usb_c67x00_drv_probe, I = found it called platform_get_resource(pdev, IORESOURCE_MEM, 0). So I think I = should add some register codes for usb like uartlite or temac in virtex.c. I added = the following codes:

#ifdef = XPAR_USB_0_BASEADDR

[VIRTEX_USB_0] = =3D {

= ; .name =3D "xilix_usb",

= ; .id =3D 0,

= ; .num_resource =3D 2,

= ; .resource =3D (struct resource[]) {

= ; = {

= ; = .start =3D XPAR_USB_0_BASEADDR,

= ; = .end =3D XPAR_USB_0_HIGHADDR,

= ; = .flags =3D IORESOURCE_MEM,

= ; = },

= ; = {

= ; = .start =3D XPAR_INTC_0_USB_0_VEC_ID,

= ; = .end =3D XPAR_INTC_0_USB_0_VEC_ID,

= ; = .flags =3D IORESOURCE_IRQ,

= ; = }

= ; }

= },

#endif

and define the following macro in xparameters_ml403.h.

#define XPAR_INTC_0_USB_0_VEC_ID XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR

#define XPAR_USB_0_BASEADDR XPAR_CYPRESS_USB_PRH0_BASEADDR

#define XPAR_USB_0_HIGHADDR XPAR_CYPRESS_USB_PRH0_HIGHADDR

After that, it still can't prob the usb = device. So could you give me some suggestion about making usb work on = ml403?

Thank you very = much!
