我的配置：

i.MX6Quad
kernel稳定5.5.6
wifi模块: mwifiex_pcie
firmware : pcieuart8997_combo_v4.bin (来自https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/)

)

我试图创建一个访问点，但是当我启动hostapd时，我总是从固件中得到相同的错误：

$ hostapd -B /etc/hostapd.conf
Configuration file: /etc/hostapd.conf
[  855.225833] mwifiex_pcie 0000:01:00.0: CMD_RESP: cmd 0xf7 error, result=0x2
mlan0: interface state UNINITIALIZED->COUNTRY_UPDATE

所使用的程序：

1)负载wifi模块

$ modprobe mwifiex_pcie
[ 300.412095] mwifiex_pcie 0000:01:00.0: enabling device (0140 -> 0142)

[ 302.383574] mwifiex_pcie 0000:01:00.0: driver_version = mwifiex 1.0 (16.68.1.p179)

2)设置接口

$ ip link set mlan0 up
$ /sbin/ifup -a
$ ifconfig mlan0
 mlan0     Link encap:Ethernet  HWaddr C0:EE:XX:XX:XX:XX  
          inet addr:192.168.0.5  Bcast:0.0.0.0  Mask:255.255.255.0
          UP BROADCAST MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

我的接口文件：

auto lo
iface lo inet loopback

auto mlan0
iface mlan0 inet static
address 192.168.0.5
netmask 255.255.255.0
gateway 192.168.0.1
dns-nameservers 8.8.8.8 8.8.4.4 192.168.0.1

3)配置hostapd.conf

# interface wlan du Wi-Fi
interface=mlan0

# nl80211 avec tous les drivers Linux mac80211 
driver=nl80211

# Nom du spot Wi-Fi
ssid=my_access_point

# mode Wi-Fi (a = IEEE 802.11a, b = IEEE 802.11b, g = IEEE 802.11g)
hw_mode=g
country_code=FR

# AC
ieee80211d=1
channel=6
macaddr_acl=0

# Wi-Fi authentication required
auth_algs=1

# Beacon interval in kus (1.024 ms)
beacon_int=100

# DTIM (delivery trafic information message) 
dtim_period=2

# Maximum number of stations allowed in station table
max_num_sta=255

# Fragmentation threshold; 2346 = disabled (default)
fragm_threshold=-1

logger_syslog=-1
logger_syslog_level=2
logger_stdout=-1
logger_stdout_level=2i

wpa=2
wpa_passphrase=wifipassword
wpa_key_mgmt=WPA-PSK
wpa_pairwise=TKIP
rsn_pairwise=CCMP

4)发射主机d

hostapd -B /etc/hostapd.conf
Configuration file: /etc/hostapd.conf
[  855.225833] mwifiex_pcie 0000:01:00.0: CMD_RESP: cmd 0xf7 error, result=0x2

有人知道是什么导致了这一切吗？以及如何修复它？我搜索了很多主题，但找不到解决这个问题的方法。

如果有人有同样的问题，这里的解决方案是：

1)负载wifi模块

modprobe mwifiex_pcie

2)设置接口

要用mwifiex_pcie驱动程序创建访问点，我们需要添加另一个接口: uap0

iw dev mlan0 interface add uap0 type __ap

我们应该拥有: lo，mlan0和uap0与$ifconfig

3)然后，使用接口hostapd.conf配置接口文件和uap0文件
