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] = {

           .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!

 

Peter Luan
