1. 修改uClinux-dist/linux-2.6.x/arch/blackfin/mach-bf561/boards/ezkit.c文件,添加ISP1362设备驱动

代码
// Add ISP1362
#if defined(CONFIG_USB_ISP1362_HCD) || defined(CONFIG_USB_ISP1362_HCD_MODULE)
static struct resource isp1362_hcd_resources[] = {
    [
0= {
        .start 
= 0x2C030000,
        .end 
= 0x2C030000,
        .flags 
= IORESOURCE_MEM,
              },
    [
1= {
        .start 
= 0x2C030002,
        .end 
= 0x2C030002,
        .flags 
= IORESOURCE_MEM,
              }, 
    [
2= {
        .start 
= IRQ_PF46,
        .end 
= IRQ_PF46,
        .flags 
= IORESOURCE_IRQ | IORESOURCE_IRQ_LOWLEVEL,
          },
};

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

 

在static struct platform_device *ezkit_devices[] __initdata结构体中添加ISP1362

 

#if defined(CONFIG_USB_ISP1362_HCD) || defined(CONFIG_USB_ISP1362_HCD_MODULE)
    
&isp1362_hcd_device,
#endif

 

2. 修改uClinux-dist/linux-2.6.x/drivers/usb/host/ISP1362.h,添加延时语句asm("ssync;");

3. 配置内核,选中ISP1362,编译内核,内核启动完成后,插入U盘会有信息回写。
