ISP1362 - DE2-70 - kernel 2.6.30

Question

After upgrading to 2.6.30 uClinux-dist and using ISP1362 component  ISP1362_CTRL.v from http://www.nioswiki.com/@api/deki/files/131/=isp1362_ctrl.v (http://www.nioswiki.com/@api/deki/files/131/=isp1362_ctrl.v)  The  only way i found for getting work full USB Host with Mass Storage Support, it was ommitting clock  check at function isp1362_hc_reset  
static int isp1362_hc_reset(struct usb_hcd *hcd)
{
	int ret = 0;
	struct isp1362_hcd *isp1362_hcd = hcd_to_isp1362_hcd(hcd);
	unsigned long t;
	unsigned long timeout = 100;
	unsigned long flags;
	int clkrdy = 0;
        
	 /*Se omite la revisión del reloj*/
	return 1;
        ..........................

Hi,

I don't know if it is the best post to write about this, but I do it because it is about the ISP1362 and also I work with a de2-70 fpga.

I use linux with MMU and the component is the one of nioswiki, ISP1362_control.v

When I boot uclinux in the initialization screen appear two lines with an error.

1-isp1362-hcd isp1362-hcd: can't setup

2-isp1362_probe: init error, -19

--- Quote Start ---

isp1362_hc_reset:

Clock not ready after 100ms

isp1362-hcd isp1362-hcd: can't setup

isp1362-hcd isp1362-hcd: USB bus 1 deregistered

isp1362_probe: init error, -19

Initializing USB Mass Storage driver...

usbcore: registered new interface driver usb-storage

USB Mass Storage support registered.

--- Quote End ---

I think that it has relationed with the address of the component(ISR1362) and the irq, I have checked that were the same as in custom_fpga.h.

I would appreciate if someone can suggest some idea about which thing I do wrong.

Thanks a lot

Hi,  I have look for the function that gives this error. It is usb_add_hcd in hcd.c   This is the peace of code that not fulfill, but I don't know which is the source    --- Quote Start ---       printk(KERN_ERR "Valor menor que uno PUFF: %d
",hcd-&gt;driver-&gt;reset(hcd));     if (hcd-&gt;driver-&gt;reset &amp;&amp; (retval = hcd-&gt;driver-&gt;reset(hcd)) &lt; 0) {         dev_err(hcd-&gt;self.controller, "can't setup
");         printk(KERN_ERR "Peta aki
");         goto err_hcd_driver_setup;     }   --- Quote End ---  Thanks for help
