Known Issues

Component	CQ ID	Issue Description	Workaround	Comments
Kernel	SDOCM00101019	AM335xEVM1.0- several mmc io error messages are displayed on the console while the board is running	NA	Observed only with some selected class 10 and class 6 SD cards
Network	SDOCM00101021	AM335xEVM1.0-Network UDP performance is very low	NA	The UDP performance is low due to the android patches applied from mainline. The issue is reported at upstream, but no fixes available yet.
ADB	SDOCM00101384	AM335x Ver 2.1 Board with JB Ver 4.2.2 loses serial and adb connection.	Use ADB over Ethernet	It is found in regression testing. Does not impact normal operation.
System	SDOCM00101385	AM335x-SK2.1- System hangs after multiple USB<->MMC/SD operation	NA	This could be because of memory limitation on AM335x SK which has only 256M.
Camera	SDOCM00102178	AM335x-SK2.1 Camera: Video feature is not working correctly	NA	On AM335x SK 2.1, only 256M memory is available. This restricts the amount contiguous memory required for video capture. Also, video capture is started, when enough free memory is created by android system, but it takes 1-2 minutes after starting video capture.
Bluetooth	SDOCM00102180	AM335x-SK2.1 Bluetooth object push takes a long time to start and transfer the file	NA	AM335x SK runs into low memory issues and so the delays are seen. This will not be the case on devices with more RAM.
System	SDOCM00102209	AM335x-SK2.1-Sometimes the board goes into a state where touchscreen responses are very slow	NA	AM335X SK has only 256M memory. When a number of applications are launched, the available free memory becomes too low and the system responsiveness becomes slow
Display	-	HDMI output on BeagleBone Black may not work after rebooting device by reboot command or pressing RESET button or	Perform a hard reboot by pulling out the Power cable and re-connecting	-
System	-	LCD7 Cape with attached Camera Cape may not be detected on BeagleBone Black	NA	No issues observed in detecting either LCD7 Cape or Camera Cape. Issue occurs only when both capes are used together. Also, this is not observed when Camera Cape is used with LCD4 Cape
