hi3518e移植USB-WiFi RT3070 STA驅動

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

                                       步驟    1    （USB PHY被禁用）

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

熱插拔usb無反應（沒有打印一下信息）：

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

1、查看你是否加載了hi3518e的驅動。

2、查看hi3518e的驅動腳本

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

3、查看是否是驅動腳本中的lowpower.sh，禁止了熱插拔。

#!/bin/sh
#....USB PHY..........0x20050080 [12]bit......0
himm 0x20050080 0x000121a8
#....USB PHY............0x20050084 [22]bit......1
himm 0x20050084 0x005d2188
#....NANDC..0x200300D0 [1:0]......2'b01
himm 0x200300D0 0x5
。。。

4、果然禁用了USB PHY，這裏我們只需要註釋掉，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'b01
himm 0x200300D0 0x5
。。。

                                       步驟    2  （內核配置）

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

複製hi3518e的配置文件到.config

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

配置內核參數

#make menuconfig
   [*] Networking support  --->
        -*-   Wireless  --->  
                 <*>   cfg80211 - wireless configuration API

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

                                       步驟   3  （編譯RT3070驅動）

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

1、修改Makfile,如下:

ifeq ($(TARGET),)
    TARGET = LINUX        / /目標平臺
endif
ifeq ($(CHIPSET),)
    CHIPSET = 3070        //使用芯片
endif
    .....
#PLATFORM = PC
PLATFORM = 5VT        //選擇平臺
    ....
ifeq ($(PLATFORM),5VT)
LINUX_SRC = /root/hi3518/linux-3.0.y            //剛剛編譯好的內核的目錄（一定要編譯好內核才行）
CROSS_COMPILE = arm-hisiv100nptl-linux-        //HI編譯工具鏈
#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

     修改參數

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

    搜索5VT

ifeq ($(PLATFORM),5VT)
#WFLAGS += -DCONFIG_5VT_ENHANCE   //屏蔽flags參數，hi3518e引腳是3.3v
endif
    。。。
ifeq ($(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) //參數和cflags一樣，但是要去掉 -mabi=apcs-gnu和 -Wno-pointer-sign 兩個參數
#export CFLAGS
export EXTRA_CFLAGS        //將cflags 修改爲 extra_cflags, 不然編譯不通過。

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、編譯

 

   #make

6、生成os/linux/rt3070sta.ko

7、複製運行配置文件（可自己修改配置），到板端文件系統

 

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

8、加載驅動

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

注：

    1、請嚴格按照步驟進行，因爲兩步之間相互有影響。

    2、如果重新編譯內核後，驅動不可用，可以嘗試重新編譯驅動。

    3、郵箱網卡不可用，可修改內核，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)
