Bug Description

In the latest staging-origen build with branch "linaro_android_2.3.5", the "wifi" directory and the wpa configuration file "wpa_supplicant.conf" under the "wifi" directory are missing from the path "/system/etc".

The "wifi" directory should be generated during the system compiling, and the file "wpa_supplicant.conf" should be copied by "AndroidBoard.mk" from "device/linaro/origen" to "/system/etc/wifi". Now both "wifi" directory and "wpa_supplicant.conf" are missing.

Following is the directory structure under the path "out/target/product/origen/system/etc":

The Android platform build can be done successfully and I didn't find any error in the build log - You can find it in attachment.

The current walk around method is to create that directory and wpa configuration file manually to SD card.

@Botao
I saw your log message and found out the bug inside kernel.
and Kernel is trapped by the following bug.

This is coming from touchscreen driver, not from WLAN driver.
