說明
之前有拿到一個mf831的4G網卡移植過，但最近發現另外一個mf831使用不了，找到了原因特此在來寫一篇。具體原因是上一篇的mf831轉化之後id爲19d2.0017，現在拿到的轉化之後是19d2.1405.貌似是國行版和國際版的區別
查看手中的網卡
插入網卡後系統將自己轉化網卡，待轉完後使用lsusb查看網卡（這次是1405的卡）：
[root@FriendlyARM /]# lsusb
Bus 2 Device 1: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 1 Device 5: ID 19d2:1405 ONDA Communication S.p.A.
Bus 1 Device 2: ID 0424:2514 Standard Microsystems Corp.
Bus 1 Device 1: ID 1d6b:0002 Linux Foundation 2.0 root hub修改kernel
1- 修改option.c文件(drivers/usb/serial/option.c)
static const struct usb_device_id option_ids[] = {
{ USB_DEVICE(0x19d2,0x1405) }, /*add by wenyi 20170423*/
{ USB_DEVICE(0x19d2,0x0017) }, /*add by wenyi 20170323*/
{ USB_DEVICE(OPTION_VENDOR_ID, OPTION_PRODUCT_COLT) },2- make menuconfig ARCH=arm添加cdc驅動
i-
-Device Drivers —>
—[*] USB support —>
—–<*> USB Modem (CDC ACM) support
ii-
-Device Drivers —>
–[*] Network device support —>
—USB Network Adapters —>
—-<*> CDC Ethernet support (smart devices such as cable modems)
—-<*> CDC EEM support
—-<*> CDC NCM support
編譯內核
# make ARCH=arm CROSS_COMPILE=arm-linux- zImage -j8重新燒錄內核；插上sim卡，插到開發板上
可以看到已經分配mac地址
# ifconfig -a
