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 = 0x2C000000,
.end = 0x2C000000 + 0x7F,
.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 2c000000,2c000004 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。
