Windows 10 IoT Core Known Issues

• The keyboard input to the default boot application may be lost when launching an application via the debugger WORKAROUND: Reboot after debugging if you wish to use the default boot application via the keyboard. (1304429)
• Some USB keyboards and mice may not work on the Raspberry PI2. WORKAROUND: Use a different keyboard or mouse. A list of validated peripheral devices can be found in the documentation at http://go.microsoft.com/fwlink/?LinkId=619428
• The video output on the MinnowBoard Max may crash after unplugging the HDMI video cable and plugging it back in while the MBM is running. (2096834). WORKAROUND: Leave the HDMI cable plugged in while the MBM is running.
• Setting the orientation to “Portrait” may not be honored in a Universal App (3039042) WORKAROUND: None
• Some animated user elements may be slow to render and slow to respond to user input on the Raspberry Pi. (2735596). WORKAROUND: Do not use the animated user elements which perform poorly.
• GPIO pin 4 may behave unexpectedly when switching between drive modes (2938068) WORKAROUND: If you need to switch drive modes, use a pin other than GPIO 4
• Once the GPIO wake feature is enabled in the UEFI settings of Device Manager it may not be possible to toggle GPIO outputs or read GPIO values using the GPIO WinRT APIs for pins 0-2 on MBM (1894235). WORKAROUND: Do not enable the GPIO wake feature
• The Default startup app may conflict with itself when it is also deployed from Visual Studio (1244550). WORKAROUND: Change the default startup app to an application other than that you wish to deploy.
• Time synchronizes from the network and may be slow to synchronize the clock after a power cycle. (3283455, 2942694) WORKAROUND: Force a time update with a “w32tm /resync” command.
• When a headed application that uses the IoT Debug Broker is being debugged, an Assert may be triggered when the Debug>Stop menu item is selected. (2385747). WORKAROUND: None.
• Clicking an external link in a web browser can cause a foreground app to crash. The crash is due to the browser control attempting to have the OS open a new window or tab which is not supported by IoT Core. (3468443) WORKAROUND: Add the http or https protocol handler to your application so that the calls do not get routed to the OS.
• GetNetworkUsageAsync may throw a System.UnauthorizedAccessException (1972129). WORKAROUND: None.
• BackgroundService Tasks may be listed as both a headed and a headless tasks. (2455442). WORKAROUND: None.
• The SPI driver may return a malformed buffer which includes two extra bytes at the beginning of the buffer for WriteRead sequence on the MinnowBoard Max (3076149) WORKAROUND: Compensate for the extra bytes in the code making the call by allocating a buffer that is x-2 bytes in size.
• The IoT Core Default Application may display two different IP addresses for the same adapter where one is a stale address. (3303771). WORKAROUND: None.
• UART1 flow control/serial handshake on MBM may default to ON and cannot be turned off (2995473). WORKAROUND: Use UART2 instead for devices without flow control.
• Location (Geolocator.RequestAccessAsync()) may not work as expected. (3359968) WORKAROUND: None.
• BackgroundMediaPlayer.MessageReceivedFromForeground may crash. (3486027) WORKAROUND: The following line of code may crash: “BackgroundMediaPlayer.MessageReceivedFromForeground += OnMessageReceivedFromForeground;”. To prevent the crash, add this code so that it is executed first “var player = BackgroundMediaPlayer.Current;”
• A NULL value may be returned by SerialDevice::FromIdAsync() when devices are connected to the top USB port on MinnowBoardMax (2175837) WORKAROUND: Use the bottom USB port.
• Data breakpoints have been disabled on the Raspberry Pi2 (3370713). WORKAROUND: None at this time
• The Azure Active Directory Authentication Library may not work on Windows 10 IoT Core (3379181). WORKAROUND: Do not use the Azure Active Directory Authentication Library.
• The MinnowBoard Max and Raspberry Pi2 may be extremely slow to boot up on the first boot when using some 8GB class 10 SD cards. Slow boot times may be over 15 minutes. Subsequent boots will be much quicker on the affected cards (3416260). WORKAROUND: Do not use the affected cards.
• The SSH Service may crash when an SSH client does not gracefully close a session. (3581710, 3602012). WORKAROUND: The SSH Service will restart in this case.
• When the device name is longer than 16 characters it may bluescreen while booting with a “CRITICAL_PROCESS_DIED” message (3622767). WORKAROUND: Use less than 16 characters in the device name.
• USB speakers may not play audio on the Raspberry Pi2 (3627304). WORKAROUND: Disable the analog audio to enable USB audio.
• MediaEncodingProfile.CreateWma(Windows.Media.MediaProperties.AudioEncodingQuality.Auto) may fail on the Raspberry Pi2 with the error message “No suitable transform was found to encode or decode the content. (Exception from HRESULT: 0xC00D5212)”. (3634750) WORKAROUND: None.
