Although Samsung Origen WIFI works, but it's not stable enough. It can't pass the "enable-disable" repeat test.
For example, after you flash the images to SD card, transfer ath6k driver to path "/system/etc/firmware", then boot up the board to enable WIFI from the setting menu. It works at the first time, you can enable the WIFI successfully, then connect to a wireless access point, then surf the Internet.
But once you disable WIFI from the setting menu, you can't enable it once more. When you click the WIFI again, sometimes it shows "enabled", but then goes to "disabled" or "error". I even get the board reboot issue during this process.
The logcat output is in attachment.
