Hi,

just a little question. I am using 2.6.24-rc3 (secretlab) and I would
like to use c67x00 driver from Peter Kosgaard for USB-Host in my Xilinx ML403 board. Is there support to use USB Host in Arch=ppc Apparently I cannot select CONFIG_USB_ARCH_HAS_HCD=y option. What should I do to get the USB working? Is there any backport for hcd support in arch=ppc? Should I upgrade to powerpc ( painful ) ?

Thx,

/Albert

just a little question. I am using 2.6.24-rc3 (secretlab) and I would

The problem of not being able to select the c67x00 driver, may be solved by simply pretending that ARCH=ppc "has a HCD" ... e.g.:

drivers/usb/Kconfig +1 -0
index 755823c..eea0277 100644

 # many non-PCI SOC chips embed OHCI

BTW: For a long time I'm wondering about what is the reason for making it not selectable by default ...

C67x00 reset problems

Hi,

I am using 2.6.24-rc3 ( secretlabs git) in an ML403 where I want to
use the USB c67x00 based host with Peter Kosgaard driver. I am using it together with the sysace device for CF access ( in the ML403 those two share lines, but I managed to insert some logic to multiplex both devices). I have been able to use the c67300 without OS, but when I try to boot the kernel I am getting driver reset problems (the whole log is at the end)

[    6.882540] c67x00 c67x00.0: Device reset
failed                           
[    6.889278] c67x00: probe of c67x00.0 failed with error 65531

And of course the device cannot get probed. I think this has happened to other people before but I can't find the solution in the archive. My virtex_devices.c initialization looks like this:

#define XPAR_C67x00_USB(num) { \
.name = "c67x00", \
.id = num, \
.num_resources = 2, \

 .resource = (struct resource[]) { \
         { \
         .start = XPAR_C67X00_USB_PRH##num##_BASEADDR, \
         .end = XPAR_C67X00_USB_PRH##num##_BASEADDR + 0xf, \
         .flags = IORESOURCE_MEM, \
         }, \
         { \
         .start  = XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR, \
         .end    = XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR, \
         .flags  = IORESOURCE_IRQ, \
          }, \

}, \
.dev.platform_data = &(struct c67x00_platform_data) { \
.sie_config = C67X00_SIE1_HOST | C67X00_SIE2_PERIPHERAL_A, \
.hpi_regstep = 0x02, /* A0 not connected on 16bit bus */ \
}, \
}

/* Cypress USB C67x00 instances */
#if defined(XPAR_C67X00_USB_PRH0_BASEADDR)
XPAR_C67x00_USB(0),
#endif

and my xparameters_ml403.h like this:

/* Definitions for peripheral C67X00_USB */
#define XPAR_C67X00_USB_PRH0_BASEADDR 0xA5000000
#define XPAR_C67X00_USB_PRH0_HIGHADDR 0xA500FFFF
#define XPAR_C67X00_USB_PRH1_BASEADDR 0xA5010000
#define XPAR_C67X00_USB_PRH1_HIGHADDR 0xA501FFFF
#define XPAR_C67X00_USB_PRH2_BASEADDR 0xA5020000
#define XPAR_C67X00_USB_PRH2_HIGHADDR 0xA502FFFF
#define XPAR_C67X00_USB_PRH3_BASEADDR 0xA5030000
#define XPAR_C67X00_USB_PRH3_HIGHADDR 0xA503FFFF

#define XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR 0
#define XPAR_SYSTEM_USB_HPI_INT_MASK 0X000001

I don't know what could be wrong here. Any clues?

Re: C67x00 reset problems

Unfortunately, the 2.6.24-rc3 stuff in my git tree is really old. I've been getting all of my recent work into mainline. The CF driver is in much better shape there. The c67x00 driver is merged into mainline, but I haven't tested it at all in the last year so I don't know how well it will work.

Cheers,
g.

Hi,

=A0I am using 2.6.24-rc3 ( secretlabs git) in an ML403 where I want to use the USB c67x00 based host with Peter Kosgaard driver. I am using it together with the sysace device for CF access ( in the ML403 those two share lines, but I managed to insert some logic to multiplex both devices). I have been able to use the c67300 without OS, but when I try to boot the kernel I am getting driver reset problems (the whole log is at the end)

[ =A0 =A06.882540] c67x00 c67x00.0: Device reset

[ =A0 =A06.889278] c67x00: probe of c67x00.0 failed with error 65531

And of course the device cannot get probed. I think this has happened to other people before but I can't find the solution in the archive. My virtex_devices.c initialization looks like this:

Re: C67x00 reset problems

I have upgraded to the latest John Linn's stable PPC kernel (2.6.25rc9) and I have applied the patch v11(latest) from Peter Korsgaard for the c67x00. I get the same problem with that, plus an added "feature" of my Xilinx Temac driver not working anymore :/

Unfortunately, the 2.6.24-rc3 stuff in my git tree is really old. I've been getting all of my recent work into mainline. The CF driver is in much better shape there. The c67x00 driver is merged into mainline, but I haven't tested it at all in the last year so I don't know how well it will work.

Cheers,
g.

Hi,

I am using 2.6.24-rc3 ( secretlabs git) in an ML403 where I want to
use the USB c67x00 based host with Peter Kosgaard driver. I am using it together with the sysace device for CF access ( in the ML403 those two share lines, but I managed to insert some logic to multiplex both devices). I have been able to use the c67300 without OS, but when I try to boot the kernel I am getting driver reset problems (the whole log is at the end)

[    6.882540] c67x00 c67x00.0: Device reset
failed
[    6.889278] c67x00: probe of c67x00.0 failed with error 65531

And of course the device cannot get probed. I think this has happened to other people before but I can't find the solution in the archive. My virtex_devices.c initialization looks like this:

#define XPAR_C67x00_USB(num) { \
.name = "c67x00", \
.id = num, \
.num_resources = 2, \

 .resource = (struct resource[]) { \
        { \
        .start = XPAR_C67X00_USB_PRH##num##_BASEADDR, \
        .end = XPAR_C67X00_USB_PRH##num##_BASEADDR + 0xf, \
        .flags = IORESOURCE_MEM, \
        }, \
        { \
        .start  = XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR, \
        .end    = XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR, \
        .flags  = IORESOURCE_IRQ, \
         }, \

}, \
.dev.platform_data = &(struct c67x00_platform_data) { \
.sie_config = C67X00_SIE1_HOST | C67X00_SIE2_PERIPHERAL_A, \
.hpi_regstep = 0x02, /* A0 not connected on 16bit bus */ \
}, \
}

/* Cypress USB C67x00 instances */
#if defined(XPAR_C67X00_USB_PRH0_BASEADDR)
XPAR_C67x00_USB(0),
#endif

and my xparameters_ml403.h like this:

/* Definitions for peripheral C67X00_USB */
#define XPAR_C67X00_USB_PRH0_BASEADDR 0xA5000000
#define XPAR_C67X00_USB_PRH0_HIGHADDR 0xA500FFFF
#define XPAR_C67X00_USB_PRH1_BASEADDR 0xA5010000
#define XPAR_C67X00_USB_PRH1_HIGHADDR 0xA501FFFF
#define XPAR_C67X00_USB_PRH2_BASEADDR 0xA5020000
#define XPAR_C67X00_USB_PRH2_HIGHADDR 0xA502FFFF
#define XPAR_C67X00_USB_PRH3_BASEADDR 0xA5030000
#define XPAR_C67X00_USB_PRH3_HIGHADDR 0xA503FFFF

#define XPAR_OPB_INTC_0_SYSTEM_USB_HPI_INT_INTR 0
#define XPAR_SYSTEM_USB_HPI_INT_MASK 0X000001

I don't know what could be wrong here. Any clues?

Re: C67x00 reset problems

In reply to Grant Likely

I have been using the mainline c67x00 driver on our boards for a while.

I am running 2.6.26-rc4 - basically the last arch/ppc version. I can only detect devices on the first port of the first host but
otherwise it has been working.

Quoted 8 lines · Grant Likely

Unfortunately, the 2.6.24-rc3 stuff in my git tree is really old. I've been getting all of my recent work into mainline. The CF driver is in much better shape there. The c67x00 driver is merged into mainline, but I haven't tested it at all in the last year so I don't know how well it will work.

Cheers,
g.

Hi,

Quoted 5 lines · A. Nolson

just a little question. I am using 2.6.24-rc3 (secretlab) and I would
like to use c67x00 driver from Peter Kosgaard for USB-Host in my Xilinx ML403 board. Is there support to use USB Host in Arch=ppc Apparently I cannot select CONFIG_USB_ARCH_HAS_HCD=y option. What should I do to get the USB working?

The problem of not being able to select the c67x00 driver, may be solved by simply pretending that ARCH=ppc "has a HCD" ... e.g.:

That sounds weird... how do other SoCs do ?

If you don't have PCI, look at the embedded section.

Ben.
