交叉编译后生成 insmod 后可以看到下面的信息 # ifconfig eth0      Link encap:Ethernet  HWaddr B6:63:E1:B8:42:D4             inet addr:192.168.1.20  Bcast:192.168.1.255  Mask:255.255.255.0           inet6 addr: fe80::b463:e1ff:feb8:42d4/64 Scope:Link           UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:976 errors:0 dropped:0 overruns:0 frame:0           TX packets:228 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:1058883 (1.0 MiB)  TX bytes:33700 (32.9 KiB)           Interrupt:56 wlan0     Link encap:Ethernet  HWaddr 00:1D:43:F1:09:AE             UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1           RX packets:0 errors:0 dropped:0 overruns:0 frame:0           TX packets:0 errors:0 dropped:0 overruns:0 carrier:0           collisions:0 txqueuelen:1000           RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B) 但是 iwconfig wlan0     no wireless extensions. 求支招，是哪个地方配置不对？kernel ?

谁能告诉我3520D V200和V300的区别？ 还有人拿到V300的资料了？

Error instantiating RTE components Error #541: 'Keil::Device:Startup:1.0.0' component is missing, pack 'Keil.STM32F0xx_DFP.1.0.0' is not installed 刚刚使用 MDK 4.6的版本报上面的错误，发现4.6没有对STM32F030的支持。所以换成 MDK5.0出现如上错误。 解决方法：到Keil的安装目录下，uv4 下有个PackInstaller的东西 。安装相应的包。

STM32F030 是Cotex-M0的内核，芯片出来不久，所以以前版本的keil是不支持的。 有两种解决方法： 第一种，安装最新的MDK，测试了 5.1里面是有STM32F030的支持的。 其中device是通过 Package Installer安装的。这个注意下， 这个是新版本keil的新特性，就是支持在线安装device支持。   第二种，安装 MDK-ARM_AddOn_STM32F030 ，这个在4.73的版本测试可用。能添加进去f030的支持。 方便大家上传上来。
