hi3518e移植USB-WiFi RT3070 STA驱动

/**************************************************************************************************/

                                       步骤    1    （USB PHY被禁用）

/**************************************************************************************************/

热插拔usb无反应（没有打印一下信息）：

# usb 1-1: new high speed USB device number 3 using hiusb-ehci

1、查看你是否加载了hi3518e的驱动。

2、查看hi3518e的驱动脚本

insert_ko(){    # low power control    source ./lowpower.sh > /dev/null。。。。

3、查看是否是驱动脚本中的lowpower.sh，禁止了热插拔。

#!/bin/sh#....USB PHY..........0x20050080 [12]bit......0himm 0x20050080 0x000121a8#....USB PHY............0x20050084 [22]bit......1himm 0x20050084 0x005d2188#....NANDC..0x200300D0 [1:0]......2'b01himm 0x200300D0 0x5。。。

4、果然禁用了USB PHY，这里我们只需要注释掉，做如下更改：

#....USB PHY..........0x20050080 [12]bit......0#himm 0x20050080 0x000121a8#....USB PHY............0x20050084 [22]bit......1#himm 0x20050084 0x005d2188#....NANDC..0x200300D0 [1:0]......2'b01himm 0x200300D0 0x5。。。

/**************************************************************************************************/

                                       步骤    2  （内核配置）

/**************************************************************************************************/

复制hi3518e的配置文件到.config

#cp arch/arm/configs/hi3518e_mini_defconfig ./.config

配置内核参数

#make menuconfig   [*] Networking support  --->        -*-   Wireless  --->                   <*>   cfg80211 - wireless configuration API                       [*]     enable powersave by default                      [*]     cfg80211 wireless extensions compatibility                      [*]   Wireless extensions sysfs files                                              <*>   Common routines for IEEE802.11 drivers                 <*>   Generic IEEE 802.11 Networking Stack (mac80211)                                 [ ]   PID controller based rate control algorithm                                   [*]   Minstrel                                                                        [*]     Minstrel 802.11n support                                                             Default rate control algorithm (Minstrel)  --->                               [ ]   Select mac80211 debugging features  --->                   Device Drivers  --->   [*] Network device support  --->         [*]   Wireless LAN  --->               <*>   USB ZD1201 based Wireless device support   [*] USB support  --->           -*-   Support for Host-si        [*]hiusb(ehci/ohci) family usb host device support  --->         <*>   EHCI HCD (USB 2.0) support                [*]     Root Hub Transaction Translators         <*>   OHCI HCD support#make uImage

/**************************************************************************************************/

                                       步骤   3  （编译RT3070驱动）

/**************************************************************************************************/

1、修改Makfile,如下:

ifeq ($(TARGET),)    TARGET = LINUX        / /目标平台endififeq ($(CHIPSET),)    CHIPSET = 3070        //使用芯片endif    .....#PLATFORM = PCPLATFORM = 5VT        //选择平台    ....ifeq ($(PLATFORM),5VT)LINUX_SRC = /root/hi3518/linux-3.0.y            //刚刚编译好的内核的目录（一定要编译好内核才行）CROSS_COMPILE = arm-hisiv100nptl-linux-        //HI编译工具链#LINUX_SRC = /home/ralink-2860-sdk-5vt-distribution/linux-2.6.17#CROSS_COMPILE = /opt/crosstool/uClibc_v5te_le_gcc_4_1_1/bin/arm-linux-endif     .... 

2、修改os/linux/config.mk

     修改参数

# Support Wpa_Supplicant#HAS_WPA_SUPPLICANT=n HAS_WPA_SUPPLICANT=y# Support Native WpaSupplicant for Network Maganger#HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=nHAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y

    搜索5VT

ifeq ($(PLATFORM),5VT)#WFLAGS += -DCONFIG_5VT_ENHANCE   //屏蔽flags参数，hi3518e引脚是3.3vendif    。。。ifeq ($(PLATFORM),5VT)#CFLAGS := -D__KERNEL__ -I$(LINUX_SRC)/include -I$(RT28xx_DIR)/include -mlittle-endian -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -O3 -fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-omit-frame-pointer -mapcs -mno-sched-prolog -mabi=apcs-gnu -mno-thumb-interwork -D__LINUX_ARM_ARCH__=5 -march=armv5te -mtune=arm926ej-s --param max-inline-insns-single=40000  -Uarm -Wdeclaration-after-statement -Wno-pointer-sign -DMODULE $(WFLAGS)  EXTRA_CFLAGS := -D__KERNEL__ -I$(LINUX_SRC)/include -I$(RT28xx_DIR)/include -mlittle-endian -Wall -Wundef -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -O3 -fno-omit-frame-pointer -fno-optimize-sibling-calls -fno-omit-frame-pointer -mapcs -mno-sched-prolog -mno-thumb-interwork -D__LINUX_ARM_ARCH__=5 -march=armv5te -mtune=arm926ej-s --param max-inline-insns-single=40000  -Uarm -Wdeclaration-after-statement -DMODULE $(WFLAGS) //参数和cflags一样，但是要去掉 -mabi=apcs-gnu和 -Wno-pointer-sign 两个参数#export CFLAGSexport EXTRA_CFLAGS        //将cflags 修改为 extra_cflags, 不然编译不通过。

3、修改  ./chips/rtmp_chip.c 文件，如下：

...#ifdef RT30xx if (IS_RT30xx(pAd)) {/*  if (IS_RT3390(pAd))   RT33xx_Init(pAd);  else*/   RT30xx_Init(pAd); }#endif /* RT30xx */...

4、修改./include/iface/rtmp_usb.h文件，如下：

...//#define RXBULKAGGRE_SIZE 12#define RXBULKAGGRE_SIZE 6...

5、编译

 

   #make

6、生成os/linux/rt3070sta.ko

7、复制运行配置文件（可自己修改配置），到板端文件系统

 

  #cp RT2870STA.dat  /etc/Wireless/RT2870STA/RT2870STA.dat

8、加载驱动

 #insmod   rt3070sta.ko rtusb init rt2870 --->=== pAd = c2a78000, size = 509944 ===<-- RTMPAllocTxRxRingMemory, Status=0<-- RTMPAllocAdapterBlock, Status=0usbcore: registered new interface driver rt2870

注：

    1、请严格按照步骤进行，因为两步之间相互有影响。

    2、如果重新编译内核后，驱动不可用，可以尝试重新编译驱动。

    3、邮箱网卡不可用，可修改内核，如下：        

Device Drivers  --->   [*] Network device support  --->         [*]   Ethernet (10 or 100Mbit)  --->             <*>   hieth(switch fabric) family network device support  --->                    (1)   hieth mii/rmii mode for up port (mii:0/rmii:1)                       (1)   hieth mii/rmii mode for down port (mii:0/rmii:1)
