+  abstract: >
+    As the Internet of Things (IoT) emerges, compact operating systems (OSs) are
+    required on low-end devices to ease development and portability of IoT
+    applications. RIOT is a prominent free and open source OS in this space. In
+    this paper, we provide the first comprehensive overview of RIOT. We cover
+    the key components of interest to potential developers and users: the
+    kernel, hardware abstraction, and software modularity, both conceptually and
+    in practice for various example configurations. We explain operational
+    aspects like system boot-up, timers, power management, and the use of
+    networking. Finally, the relevant APIs as exposed by the OS are discussed
+    along with the larger ecosystem around RIOT, including development and open
+    source community aspects.

+@brief       Support for the Alientek Pandora board
+
+## Overview
+
+The Alientek Pandora is a development board manufactured jointly by Alientek and RT-Thread company.
+It is based on STM32L475VET6 and have on-board LCD, SD card and WiFi access.
+Users may connect to its on board ST-Link 2.1 compatible debugger to flash or debug.
+
+Documents of this board are available on its [Alientek official website](http://www.alientek.com/productinfo/716137.html).
+It may require a translation software to read it in English.
+Additional resources may be found on [RT-Thread bsp support page](https://gitee.com/rtthread/rt-thread/tree/master/bsp/stm32/stm32l475-atk-pandora).
+
+### Flashing the board
+
+To flash the board, use the on board ST-Link programmer/debugger.
+Input the following command:
+
+    make BOARD=alientek-pandora -C examples/hello-world flash
+
+The NRST pin is connected to the on board debugger, so users do not need to reset manually
+every time it requires to flash.
+
+If the operating system raised a fault, users may manually reset the chip by pressing the reset button.
+This button has a black color and is located between the four keys and the LED light.
+
+### STDIO
+
+STDIO is connected to pins PA9 (TX) and PA10 (RX).
+Before you begin, check that the both the jumper caps marked as 'USART1' is connected.
+
+Use the `term` target to open a terminal:
+
+    make BOARD=alientek-pandora -C examples/hello-world term
+
+An on-board ST-Link compatible debugger is used to transport serial STDIO message.

+@brief       Support for the STM32 B-U585I-IOT02A
+
+## Flashing the device
+
+The ST B-U585I-IOT02A board includes an on-board ST-LINK programmer and can be
+flashed using OpenOCD.
+@note The latest release (v0.11) of OpenOCD doesn't contain yet support for this board,
+so the source code version from upstream master must be cloned and built:
+
+```
+$ git clone https://git.code.sf.net/p/openocd/code openocd
+$ cd openocd
+$ ./bootstrap
+$ ./configure --prefix=<installation directory>
+$ make -j
+$ sudo make install
+```
+
+Once the patched OpenOCD is built and installed, you can flash the board simply
+by typing
+
+```
+make BOARD=b-u585i-iot02a flash
+```
+
+and debug via GDB by simply typing
+```
+make BOARD=b-u585i-iot02a debug
+```
+
+## Supported Toolchains
+
+For using the ST B-U585I-IOT02A board we recommend the usage of the
+[GNU Tools for ARM Embedded Processors](https://launchpad.net/gcc-arm-embedded)
+toolchain.
+
+**Important notice:** With GCC 10, the `tests/malloc` application doesn't work.
+To use malloc, prefer GCC 9 which seems to work better.
