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......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，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'b01
himm 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 ($(TARGET),)
TARGET = LINUX / /目标平台
endif
ifeq ($(CHIPSET),)
CHIPSET = 3070 //使用芯片
endif
.....
#PLATFORM = PC
PLATFORM = 5VT //选择平台
....
ifeq ($(PLATFORM),5VT)
LINUX_SRC = /root/hi3518/linux-3.0.y //刚刚编译好的内核的目录（一定要编译好内核才行）
CROSS_COMPILE = arm-hisiv100nptl-linux- //HI编译工具链
#LINUX_SRC = /home/ralink-2860-sdk-5vt-distribution/linux-2.6.17
#CROSS_COMPILE = /opt/crosstool/uClibc_v5te_le_gcc_4_1_1/bin/arm-linux-
endif
....
2、修改os/linux/config.mk
修改参数
# Support Wpa_Supplicant
#HAS_WPA_SUPPLICANT=n
HAS_WPA_SUPPLICANT=y
# Support Native WpaSupplicant for Network Maganger
#HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=n
HAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y
搜索5VT
ifeq ($(PLATFORM),5VT)
#WFLAGS += -DCONFIG_5VT_ENHANCE //屏蔽flags参数，hi3518e引脚是3.3v
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) //参数和cflags一样，但是要去掉 -mabi=apcs-gnu和 -Wno-pointer-sign 两个参数
#export CFLAGS
export 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=0
usbcore: 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)
