@晕哥
晕哥这次我终于调试好v3s的esp8089的驱动了呢
（1）下载源码 https://github.com/al177/esp8089
修改Makefile，修改如下的内容：
KVERS_UNAME = 4.13.16-licheepi-zero+
KVERS_ARCH = arm
KBUILD ?=/home/gec/v3s/linux4.13-y/linux
modules:
$(MAKE) ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -C $(KBUILD) M=$(SRC_DIR)
然后直接在文件夹内make 即可生成esp8089.ko文件
（2）参考RTL8723bs的配置方法
a.wpa_supplicant-2.6交叉编译
使用wpa_supplicant与wpa_cli相关的工具测试wifi
（1）1. libnl交叉编译
下载：https://www.infradead.org/~tgr/libnl/files/libnl-1.1.4.tar.gz
解压：tar zxvf libnl-1.1.4.tar.gz
cd libnl-1.1.4/
配置
./configure --prefix=/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out
删除：（这一步一定不能忘记）
rm lib/libnl.a
可能导致编译报错（编译出错Relocations in generic ELF (EM: 62)）
编译：make CC=arm-linux-gnueabihf-gcc AR=aarch64-linux-gnu-ar LD=arm-linux-gnueabihf-ld
make install
（2）openssl-1.0.0交叉编译
下载：https://www.openssl.org/source/old/1.0.1/openssl-1.0.1s.tar.gz
解压：tar -xzvf openssl-1.0.0.tart.gz
配置：
./config no-asm shared --prefix=/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out
修改makfile：
（1）修改交叉编译器
CC= gcc
AR= ar $(ARFLAGS) r
RANLIB= /usr/bin/ranlib
NM= nm
修改为：
CC=arm-linux-gnueabihf-gcc
AR= arm-linux-gnueabihf-ar $(ARFLAGS) r
RANLIB= arm-linux-gnueabihf-gcc-ranlib
NM= arm-linux-gnueabihf-gcc-nm
（2）去掉里面的-m64
make make install
备注：
no-asm是在交叉编译过程中不使用汇编代码代码加速编译过程.原因是它的汇编代码是对arm格式不支持的。我试过了，如果没有这个参数，你的交叉编译一定出错。shared生成动态连接库。prefix=路径 就是你的安装目录。
3. wpa_supplicant交叉编译
下载：http://hostap.epitest.fi/releases/wpa_supplicant-2.6.tar.gz
解压：tar -zxvf wpa_supplicant-2.6.tar.gz
cd wpa_supplicant-2.6/wpa_supplicant
拷贝配置：
cp defconfig .config
修改.config
（-O后面不能有空格）
CC=arm-linux-gnueabihf-gcc -L/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out/lib
CFLAGS += -I/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out/include
LIBS += -L/mnt/nfsroot/frank.yu/android-O/factorytest/wifi/out/lib
makefile修改：（这里是为了生成静态链接的bin文件）
wpa_supplicant: $(BCHECK) $(OBJS) $(EXTRA_progs)
$(Q)$(LDO) $(LDFLAGS) -o wpa_supplicant $(OBJS) $(LIBS) $(EXTRALIBS)
@$(E) " LD " $@
修改为
wpa_supplicant: $(BCHECK) $(OBJS) $(EXTRA_progs)
$(Q)$(LDO) --static $(LDFLAGS) -o wpa_supplicant $(OBJS) $(LIBS) $(EXTRALIBS) -lm -lpthread
@$(E) " LD " $@
wpa_cli: $(OBJS_c)
$(Q)$(LDO) $(LDFLAGS) -o wpa_cli $(OBJS_c) $(LIBS_c)
@$(E) " LD " $@
修改为
wpa_cli: $(OBJS_c)
$(Q)$(LDO) --static $(LDFLAGS) -o wpa_cli $(OBJS_c) $(LIBS_c)
@$(E) " LD " $@
编译：
make
即可生成静态链接的wpa_supplicant/wpa_cli工具，不需要依赖其他的库文件。
工具wpa_cli ,wpa_passphrase,wpa_supplicant拷贝进开发板的/bin 目录
三，在开发板中设置
（1）insmod esp8089.ko
然后输入ifconfig wlan0 up命令启动wlan0
(3)建立 /etc/wpa_supplicant.conf 文件:
#可有可无，没有的话无法用wpa_cli terminate来关闭wpa_supplicant
ctrl_interface=/var/run/wpa_supplicant
# 确保只有root用户能读取WPA的配置，可有可无，尤其是在嵌入式设备上
ctrl_interface_group=0
# 使用wpa_supplicant来扫描和选择AP，也可以设置成0或2，但只有1才能正确工作
ap_scan=1
#设置需要链接上的网络信息
network={
ssid="unicompy1F"
scan_ssid=1
key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
pairwise=TKIP CCMP
group=CCMP TKIP WEP104 WEP40
psk="unicomp#38468350"
priority=5
}
(4)输入命令wpa_supplicant -B -d -i wlan0 -c /etc/wpa_supplicant.conf
使用这个命令来链接上wifi
测试wlan0: udhcpc -i wlan0
补充：运维常用linux命令整理
1.临时添加
1 route add default gw 192.168.1.4
2.永久添加
12 vim /etc/sysconfig/networkGATEWAY=192.168.1.4
(5)配置网络ping通外网部分了
一.手动测试是否成功加载网卡驱动，可执行如下命令：ifconfig eth0 192.168.1.218 up
二。以下是在配置好内核以及成功加载网卡的前提下实现能够自动配置网络，能够ping通的步骤
（1）修改 /etc/network/interfaces
即vi /etc/network/interfaces后添加如下语句：
auto lo
iface lo inet loopback
auto wlan0
iface wlan0 inet static
address 192.168.1.218 # 3 你要变化的IP地址
gateway 192.168.1.251 （该网关最好需要设置成跟电脑的网关一致，我这里是 192.168.1.251,跟路由器设置相关）
netmask 255.255.255.0
（2）vi /etc/resolv.conf
添加以下语句
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
（3）为了能够实现自动开机设置
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
可以 vi /etc/init.d/rcS
然后添加以下三句即可：
echo "nameserver 127.0.0.1" > /etc/resolv.conf
echo "nameserver 202.96.134.33" >> /etc/resolv.conf
echo "nameserver 114.114.114" >> /etc/resolv.conf
之后就可以直接ping通了！！！
@晕哥
晕哥，我在 https://github.com/al177/esp8089 下载了一份esp8089的驱动源码，想进行编译时，
root@ubuntu:~/v3s/linux4.13-y/linux# make -j4 ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- modules M=../esp8089 CONFIG_ESP8089=m
make[1]: *** No rule to make target '../esp8089/esp_debug.o', needed by '../esp8089/esp8089.o'. Stop.
Makefile:1512: recipe for target '_module_../esp8089' failed
make: *** [_module_../esp8089] Error 2
想请问下晕哥，是不是我的命令有问题了，还是有其他可以参考的关于esp8089驱动编译和使用的帖子呢？
@晕哥

@晕哥
晕哥，我使用qt5.4.1的程序发现点击触摸屏没有反应
（1）执行命令/opt/tslib/bin/ts_calibrate的结果如下
xres = 480, yres = 272
Took 4 samples...
Top left : X = 2996 Y = 1998
Took 4 samples...
Top right : X = 2695 Y = 2492

（2）执行cat /dev/input/event1命令
我点击触摸屏会有一些乱码出现呢
（3）cat /etc/profile的结果如下
export PATH=/bin:/sbin:/usr/bin:/usr/sbin

请晕哥帮忙分析下。
@晕哥
晕哥，我刚才在下载下来的库中的文件中使用命令find . -name *alsa* ，发现如下结果：
root@ubuntu:/mnt/hgfs/shareubantu/licheepi/qt_test/qtmultimedia-opensource-src-5.4.1# find . -name *alsa*

是不是说libqtmedia_audioengine底层是调用alsa的呢？

# ls /dev/@晕哥
晕哥，感谢你提醒，我设置了下DNS，不过我需要根据我电脑网络的配置的网关来配置，可能是路由器的问题我电脑的网关是192.168.1.215，而不是通常的192.168.1.1,设置好之后我能够成功ping通百度了。
以下是我的网络配置步骤：
一.手动测试是否成功加载网卡驱动，可执行如下命令：ifconfig eth0 192.168.1.218 up
二。以下是在配置好内核以及成功加载网卡的前提下实现能够自动配置网络，能够ping通的步骤
（1）修改 /etc/network/interfaces 即vi /etc/network/interfaces后添加如下语句：
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 192.168.1.218 # 3 你要变化的IP地址
gateway 192.168.1.251 （该网关最好需要设置成跟电脑的网关一致，我这里是 192.168.1.251,跟路由器设置相关）
netmask 255.255.255.0
（2）vi /etc/resolv.conf
添加以下语句
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
（3）为了能够实现自动开机设置
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
可以 vi /etc/init.d/rcS
然后添加以下三句即可：
nameserver 127.0.0.1
nameserver 202.96.134.33
nameserver 114.114.114.114
之后就可以直接ping通了！！！
@晕哥
晕哥，试了上面的DNS配置，发现还是不行，仍然出现ping: bad address 'www.baidu.com'的问题
@晕哥
晕哥，我在配置v3s的网络时，出现了ping www.baidu.com时出现这个问题：
# ping www.baidu.com
ping: bad address 'www.baidu.com'

请晕哥帮忙分析下，为何我能够ping通虚拟机，虚拟机能够ping通百度，但是不能ping通百度呢？
@晕哥
晕哥，我刚才尝试了一下，tinyplay成功了，成功的步骤我总结了一下：
一。tinyplay移植
（1） git clone https://github.com/tinyalsa/tinyalsa.git
（2）把所有Makefile的 CC行都改成这样：
CC = $(CROSS_COMPILE)gcc
（3）把所有Makefile的改为
CROSS_COMPILE = arm-linux-gnueabihf-gcc；
使用的是静态链接，当然前提是要在电脑上安装了 ：
arm-linux-gnueabihf-gcc，
安装方法：sudo apt-get install gcc-arm-linux-gnueabihf
（4）在tinyalsa文件内执行make命令
（5）接着在arm板上移植步骤如下：
1.将tinyalsa/utils/下的tinycap tinymix tinypcminfo 和tinyplay 复制到开发板的/bin目录下；
2.将tinyalsa/src下的libtinyalsa.so.1 libtinyalsa.so
libtinyalsa.so.1.1.1拷贝到开发板的/lib即可。
（6）运行tinymix 来调节音量
tinymix set 1 63
tinymix set 2 1
tinymix contents
（7）在这个之前我是已经将alsa移植过一次，不知这个会不会有影响，目前还没有测试过。
@晕哥
晕哥，在使用C600的套路里面我遇到了几个问题呢，不知道怎么解决，请大神分析下：
1.单独编译linux3.10时，想提取出dtb和zImage文件，但是make ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- dtbs -j4,之后出现了错误：
include/linux/compiler-gcc.h:106:1: fatal error: linux/compiler-gcc7.h: No such file or directory
#include gcc_header(__GNUC__)
这个我尝试安装了gcc7.0还是没能解决。
2.为什么按照C600的套路我，我把镜像下载到板子之中，输入cat /proc/asound/cards之后还是提示no soundcards
请问下这个问题是不是跟我没有将alsa库移植进系统有关呢？
3.晕哥我还想请教下在C600的套路里面我想修改根文件系统，但是不知在哪个地方可以修改根文件系统？
@fly_to_bluesky
我想请教您一个问题，就是我在linux4.19的内核配置中应该怎么配置才能够配置好荔枝派nano的测试声卡呢？
我怎么配置都配置不出你的镜像中：
#cat /proc/asound/cards
0 [audiocodec ]: audiocodec - audiocodec
audiocodec
而我配来配去都没有出现这个声卡的信息，下面是我的声卡信息：
#cat /proc/asound/cards
0 [Dummy ] : Dummy - Dummy
Dummy 1
1 [Loopback ] : Loopback - Loopback
Loopback 1
2 [VirMIDI ] : VirMIDI - VirMIDI
Virtual MIDI Card 1
想请教下我的内核需要怎么配置的呢？还是需要自己编写驱动的呢？
