所用的开发板上带了一片DM9000的网络芯片,这个芯片的驱动在uclinux中自带了,所需要做的就是将它的资源添加到arch/blackfin/mach-bf561/boards/ezkit.c中。

首先添加资源定义:

static struct resource dm9000_bfin_resources[] = {

       {

              .start = 0x 2C 000000,

              .end = 0x 2C 000000 + 0x 7F ,

              .flags = IORESOURCE_MEM,

       }, {

              .start = IRQ_PF10,

              .end = IRQ_PF10,

              .flags = IORESOURCE_IRQ | IORESOURCE_IRQ_LOWLEVEL,

       },

};

 

static struct platform_device dm9000_bfin_device = {

       .name = "dm9000",

       .id = -1,

       .num_resources = ARRAY_SIZE(dm9000_bfin_resources),

       .resource = dm9000_bfin_resources,

};

然后修改ezkit_devices的定义:

static struct platform_device *ezkit_devices[] __initdata = {

…………………………………..

       &dm9000_bfin_device,

…………………………………..

};

在工程中加上net目录下的相关文件,编译运行,在启动信息中多了以下几行:

NET: Registered protocol family 16

Blackfin DMA Controller

ezkit_init(): registering device resources

NET: Registered protocol family 2

IP route cache hash table entries: 1024 (order: 0, 4096 bytes)

TCP established hash table entries: 2048 (order: 2, 16384 bytes)

TCP bind hash table entries: 2048 (order: 1, 8192 bytes)

TCP: Hash tables configured (established 2048 bind 2048)

TCP reno registered

dm9000 Ethernet Driver

eth%d: Invalid ethernet MAC address.  Please set using ifconfig

eth0: dm9000 at 2c 000000, 2c 000004 IRQ 83 MAC: 00:00:00:00:00:00

不过还不是很清楚为什么MAC地址会全部为0。需要再研究一下。
