Message: 78559

hi everyone!

my target board is ezkit-bf533 and the usb host controller is isp 1362

// ezkit.c

#if defined(CONFIG_USB_ISP1362_HCD) || defined(CONFIG_USB_ISP1362_HCD_MODULE)

static struct resource isp1362_hcd_resources[] = {

{

.start = 0x20330000,

.end = 0x20330000,

.flags = IORESOURCE_MEM,

}, {

.start = 0x20330004,

.end = 0x20330004,

.flags = IORESOURCE_MEM,

}, {

.start = IRQ_PF5,

.end = IRQ_PF5,

.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,

};

static struct isp1362_platform_data isp1362_priv = {

.sel15Kres = 1,

.clknotstop = 0,

.oc_enable = 0,

.int_act_high =0,

.int_edge_triggered =0,

.remote_wakeup_connected = 0,

.no_power_switching = 1,

.power_switching_mode = 0,

};

static struct platform_device isp1362_hcd_device = {

.name = "isp1362-hcd",

.id = 0,

.dev = {

.platform_data = &isp1362_priv,

.num_resources = ARRAY_SIZE(isp1362_hcd_resources),

.resource = isp1362_hcd_resources,

};

#endif

when I reboot the system,I found the error like this:

driver isp1362-hcd, 2005-04-04

isp1362-hcd isp1362-hcd.0: ISP1362 Host Controller

isp1362-hcd isp1362-hcd.0: new USB bus registered, assigned bus number 1

Clock not ready after 100ms

isp1362-hcd isp1362-hcd.0: can\'t setup

isp1362-hcd isp1362-hcd.0: USB bus 1 deregistered

init error, -19

after i added some debug information

I found that the return value of the function isp1362_read_data16 is always 0

I really don\'t know how to solve the problem.

//isp1362-hcd.c

clkrdy = isp1362_read_reg16(isp1362_hcd, HCuPINT) & HCuPINT_CLKRDY;

//isp1362.h

#define isp1362_read_reg16(d, r) ({ \\

isp1362_write_addr(d, ISP1362_REG_##r); \\

__v = isp1362_read_data16(d); \\

RDBG("%s: Read %04x from %s[%02x]\\n", __FUNCTION__, __v, #r, \\

ISP1362_REG_NO(ISP1362_REG_##r)); \\

__v; \\

})

static u16 isp1362_read_data16(struct isp1362_hcd *isp1362_hcd)

{

u16 val;

_BUG_ON(!irqs_disabled());

DUMMY_DELAY_ACCESS;

val = readw(isp1362_hcd->data_reg);

//printk("val= %d\\n",val);

return val;

}

after I remove the codes:

//isp1362-hcd.c

//if (!clkrdy) {

//ERR("Clock not ready after //%lums\\n", timeout);

//ret = -ENODEV;

//}

new problem appeared : Invalid chip ID 0000

//isp1362-hcd.c

spin_lock_irqsave(&isp1362_hcd->lock, flags);

chipid = isp1362_read_reg16(isp1362_hcd, HCCHIPID);

spin_unlock_irqrestore(&isp1362_hcd->lock, flags);

if ((chipid & HCCHIPID_MASK) != HCCHIPID_MAGIC) {

ERR("%s: Invalid chip ID %04x\\n", __func__, chipid);

return -ENODEV;

}

I assume you meant 120MHz?

What hardware are you using?

I recently tested the ISP1362-hcd driver and it worked ok.

Message: 78603 Hi Fan,

So far you failed to tell me you're Hardware.

I tested the ISP1362-HCD driver on BF533-EZKIT with the Blackfin USB

Extender Card.

docs.blackfin.uclinux.org/doku.php?id=3Dhw:cards:usb_ez-extender

See my setup below - I jumpered JP3 to J2-44 for IRQ_PF14.

See config and kernel messages below - it works great.

What you're describing can be caused be two things -=20

1) No hardware present=20

2) You use the wrong base address=20

I get exactly the same thing in case I remove the ISP1362 card from my

EZKIT and then start the kernel.

Your ISP1362_CS chip select is controlled by some glue logic inside the

CPLD on your board - I would start looking there if the ISP1362_CS

really toggles when you access ISP1362 registers.

OK.It works OK.just because the CS pin didn't toggle.

thank you very much Michael.

Hi, Chunbo Fan, I'm using the same platform with and meet the same problem with you.

Can you explain the "CS pin didn't toggle" and how do you solve the problem??

Thanks very much,,,
