我有一个运行的嵌入式arm linux设备
kernel 2.6.39.4
hostapd 2.0
wl1271 and wl1271_sdio modules loaded (no compat drivers)
该设备是TI的TiWi-R2模块。Adhoc和Infrastructure模式可以工作，但当我尝试设置softap时，我遇到了问题：我通过将hostapd.conf的内容设置为：，创建了一个没有加密的工作站
interface=wlan0
driver=nl80211
channel=1
hw_mode=g
ssid=mya
正在启动的固件：
[ 6486.330000] wl1271: wlan power up
[ 6486.660000] booting firmware ti-connectivity/wl1271-fw-ap.bin
[ 6486.810000] wl1271: firmware booted (Rev 6.2.1.0.54)
SSID正在广播，其他设备可以看到它，但无法关联。在Ubuntu笔记本电脑上，在尝试连接失败后，我从dmesg:得到了以下信息
[ 548.289020] wlan0: authenticate with 00:xx:yy:zz:ww:qq
[ 548.300588] wlan0: send auth to 00:xx:yy:zz:ww:qq (try 1/3)

[ 548.708059] wlan0: send auth to 00:xx:yy:zz:ww:qq (try 3/3)
[ 548.912056] wlan0: authentication with 00:xx:yy:zz:ww:qq timed out
关联失败后，笔记本电脑将连接到另一个先前配置的接入点。在嵌入式设备上用-dd选项启动hostapd，我可以得到一些调试消息，但我不太理解。这是笔记本电脑连接时hostapd侧的输出：

过了一段时间，系统似乎因为不活动而解除了与笔记本电脑的关联：

我在bugzilla中看到了一篇类似的帖子，但这篇帖子很旧，属于wpa_pplient（版本0.6.0），笔记本电脑上有Ubuntu 13.04和wpa_pplint 1.0。这让我觉得，不知何故，hostapd没有通知客户端关联成功。
我也无法从任何其他设备连接到软地图。我尝试了Android 4.4和iOS 7.0.4
我还尝试了wpa2配置和TI的标准开放配置文件，但都没有成功。
编辑：我没想到我会在这件事上向整个社区施压。。。我已经升级到TiWi-BLE模块，这是TiWi-R2的官方继任者，但还没有进一步升级。
我在这里找到了一个有同样问题但没有解决方案的帖子。
编辑：我已经通过使用3.12.0内核解决了这个问题，其中没有出现这个问题。在我看来问题出在内核上。我会暂时不回答这个问题，以防有人看到它。
我切换到了一个更新的内核。当时它是3.13.0-next，一个没有正式发布的内核，但由于它运行得很好，我一直保持这个版本。
