Microsoft has today released a new Insider Preview build for Windows 10 IoT Core. The company today released Build 10556, which packs a number of improvements and bug fixes. Here’s what’s new in today’s release:
- Serial support on Raspberry Pi for TX and RX pins
- High performance GPIO driver option with > 100x improvement
- Arduino Wiring Project System for Visual Studio
- Support for the TPLink WiFi dongle on Raspberry Pi2
- Updated base OS build
- Bug Fixes
Alongside the latest additions, the latest build also includes a few known issues, which are listed below:
- Setting the orientation to “Portrait” may not be honored in a Universal App (3039042) WORKAROUND: None
- GPIO pin 4 may behave unexpectedly when switching between drive modes (3890679) WORKAROUND: If you need to switch drive modes, use a pin other than GPIO 4
- The Default startup app may conflict with itself when it is also deployed from Visual Studio (4266059). WORKAROUND: Change the default startup app to an application other than that you wish to deploy.
- GetNetworkUsageAsync may throw a System.UnauthorizedAccessException (1972129). 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.
- 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 (4266252). WORKAROUND: Data breakpoints will be enabled in a future release.
- The Azure Active Directory Authentication Library may not work on Windows 10 IoT Core (4266261). WORKAROUND: Do not use the Azure Active Directory Authentication Library.
- More.com!PAGER::DisplayString may return INVALID_POINTER_READ exception. (1552523) WORKAROUND: None.
- The time may not sync on devices running IoT Core. (4444681) Manually update the time or programmatically force a time sync.
