这次真破案了， 把同一个 img 文件烧录到 spi flash，wifi连接正常，说明还是 /etc 目录无写入权限引起。 -

以下是SPI NAND FLASH版本启动后执行 mount目录的信息，由于加载overlayfs 文件系统，这样就可以写 /etc/ 目录了
root@TinaLinux:/# mount /dev/root on /rom type squashfs (ro,noatime) devtmpfs on /dev type devtmpfs (rw,relatime,size=504012k,nr_inodes=126003,mode=755) proc on /proc type proc (rw,nosuid,nodev,noexec,noatime) sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,noatime) tmpfs on /tmp type tmpfs (rw,nosuid,nodev,noatime) /dev/by-name/UDISK on /overlay type ubifs (rw,relatime,assert=read-only,ubi=0,vol=8) overlayfs:/overlay on / type overlay (rw,noatime,lowerdir=/,upperdir=/overlay/upper,workdir=/overlay/work) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,mode=600,ptmxmode=000) debugfs on /sys/kernel/debug type debugfs (rw,noatime) none on /sys/kernel/config type configfs (rw,relatime) adb on /dev/usb-ffs/adb type functionfs (rw,relatime) root@TinaLinux:/#root@TinaLinux:/# find / -name wpa_supplicant.conf /etc/wifi/wpa_supplicant.conf /overlay/upper/etc/wifi/wpa_supplicant.conf /rom/etc/wifi/wpa_supplicant.conf读写 /etc/wifi/wpa_supplicant.conf
文件时， 如果发现 /overlay/upper/etc/wifi/wpa_supplicant.conf 存在，则不会访问 /rom/etc/wifi/wpa_supplicant.conf 文件。 -

如果是烧卡启动，系统是把 只读的squashfs挂到根文件系统 /
并没有可读写的 overlayfs ，所以出现了 /etc/ 目录不可写的问题

看了一下源码，还真是要写 /etc/ 目录下面的文件：

大概知道原因了，把 img 烧到 TF卡启动，然后执行 wifi_connect_ap_test 是连不上的。
然后我手动建立 /etc/wpa_supplicant.conf 提示只读，创建文件失败，
然后我再建立 /tmp/wpa_supplicant.conf
ctrl_interface=/var/run/wpa_supplicant ctrl_interface_group=0 ap_scan=1 network={ ssid="ubuntu" scan_ssid=1 key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE pairwise=TKIP CCMP group=CCMP TKIP WEP104 WEP40 psk="13800138000" priority=5 }root@TinaLinux:/# wpa_supplicant -B -d -i wlan0 -c /tmp/wpa_supplicant.conf Successfully initialized wpa_supplicant [ 565.756909] ieee80211_do_open: vif_type=2, p2p=0, ch=3, addr=70:f4:4d:76:31:86 [ 565.765681] [STA] !!!xradio_vif_setup: id=0, type=2, p2p=0, addr=70:f4:4d:76:31:86 [ 565.779627] [AP_WRN] BSS_CHANGED_ASSOC but driver is unjoined.root@TinaLinux:/# udhcpc -i wlan0 udhcpc: started, v1.27.2 udhcpc: sending discover udhcpc: sending select for 192.168.151.222 udhcpc: lease of 192.168.151.222 obtained, lease time 3599 udhcpc: ifconfig wlan0 192.168.151.222 netmask 255.255.255.0 broadcast 192.168.151.255 udhcpc: setting default routers: 192.168.151.42 root@TinaLinux:/# root@TinaLinux:/# root@TinaLinux:/# ping www.163.com PING www.163.com (36.158.202.26): 56 data bytes 64 bytes from 36.158.202.26: seq=0 ttl=53 time=54.414 ms 64 bytes from 36.158.202.26: seq=1 ttl=53 time=60.232 ms 64 bytes from 36.158.202.26: seq=2 ttl=53 time=58.636 ms也就是说wifi本身没什么问题，估计是那些 wifi tools 需要可读写文件系统的原因，我再观察观察。
