说明
之前有拿到一个mf831的4G网卡移植过，但最近发现另外一个mf831使用不了，找到了原因特此在来写一篇。具体原因是上一篇的mf831转化之后id为19d2.0017，现在拿到的转化之后是19d2.1405.貌似是国行版和国际版的区别
查看手中的网卡
插入网卡后系统将自己转化网卡，待转完后使用lsusb查看网卡（这次是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驱动
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
编译内核
# make ARCH=arm CROSS_COMPILE=arm-linux- zImage -j8重新烧录内核；插上sim卡，插到开发板上
可以看到已经分配mac地址
# ifconfig -a
