+# OpenThread on nRF52833 Example
+
+This directory contains example platform drivers for [Nordic Semiconductor nRF52833 SoC][nRF52833].
+
+To facilitate Thread products development with the nRF52833 platform, Nordic Semiconductor provides <i>nRF5 SDK for Thread and Zigbee</i>. See [Nordic Semiconductor's nRF5 SDK for Thread and Zigbee][nRF5-SDK-section] section for more details.
+
+[nRF52833]: https://www.nordicsemi.com/Products/Low-power-short-range-wireless/nRF52833
+[nRF5-SDK-section]: #nordic-semiconductors-nrf5-sdk-for-thread-and-zigbee
+
+## Prerequisites
+
+Before you start building the examples, you must download and install the toolchain and the tools required for flashing and debugging.
+
+### Toolchain
+
+Download and install the [GNU toolchain for ARM Cortex-M][gnu-toolchain].
+
+[gnu-toolchain]: https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm
+
+To install the GNU toolchain and its dependencies, run the following commands in Bash:
+
+```bash
+$ cd <path-to-openthread>
+$ ./script/bootstrap
+```
+
+### Flashing and debugging tools
+
+[nRF5-Command-Line-Tools]: https://www.nordicsemi.com/Software-and-Tools/Development-Tools/nRF5-Command-Line-Tools
+
+Install the [nRF5 Command Line Tools][nRF5-Command-Line-Tools] to flash, debug, and make use of logging features on the nRF52833 DK with SEGGER J-Link.
+
+## Building the examples
+
+ To build the examples, run the following command in Bash:
+
+```bash
+$ cd <path-to-openthread>
+$ ./bootstrap
+$ make -f examples/Makefile-nrf52833
+```
+
+After a successful build, the `elf` files can be found in
+`<path-to-openthread>/output/nrf52833/bin`.
+You can convert them to hex using `arm-none-eabi-objcopy`:
+```bash
+$ arm-none-eabi-objcopy -O ihex ot-cli-ftd ot-cli-ftd.hex
+```
+
+### USB CDC ACM support
+
+You can build the libraries with support for the native USB CDC ACM as a serial transport.
+To do so, build the firmware with the following parameter:
+```
+$ make -f examples/Makefile-nrf52833 USB=1
+```
+
+Note that the USB CDC ACM serial transport is not supported with Engineering sample A of the nRF52833 chip.
+
+If you are using Windows 7 or earlier, you must load an additional USB CDC driver.
+The driver can be found in `third_party/NordicSemiconductor/libraries/usb/nordic_cdc_acm_example.inf`.
+
+### Bootloader support
+
+The examples support the following bootloaders for performing a Device Firmware Upgrade (DFU):
+* USB bootloader
+* UART bootloader
+* BLE bootloader
+
+The support for a particular bootloader can be enabled with the following switches:
+* USB: `BOOTLOADER=USB`
+* UART: `BOOTLOADER=UART`
+* BLE: `BOOTLOADER=BLE`
+
+### Native SPI support
+
+You can build the libraries with support for native SPI Slave.
+To build the libraries, run make with the following parameter:
+
+```
+$ make -f examples/Makefile-nrf52833 NCP_SPI=1
+```
+
+With this option enabled, SPI communication between the NCP example and wpantund is possible
+(provided that the wpantund host supports SPI Master). To achieve that, an appropriate SPI device
+should be chosen in wpantund configuration file, `/etc/wpantund.conf`. You can find an example below.
+```
+Config:NCP:SocketPath "system:/usr/bin/spi-hdlc-adapter --gpio-int /sys/class/gpio/gpio25 /dev/spidev0.0"
+```
+
+In this example, [spi-hdlc-adapter][spi-hdlc-adapter] is a tool that you can use to communicate between NCP and wpantund over SPI. For this example, `spi-hdlc-adapter` is installed in `/usr/bin`.
+
+The default SPI Slave pin configuration for nRF52833 is defined in `examples/platforms/nrf52833/platform-config.h`.
+
+Note that the native SPI Slave support is not intended to be used with Engineering sample A of the nRF52833 chip due to
+single transfer size limitation.
+
+[spi-hdlc-adapter]: https://github.com/openthread/openthread/tree/master/tools/spi-hdlc-adapter
+
+### Optional prefix for compiler command
+
+You can prefix the compiler command using the CCPREFIX parameter. This speeds up the compilation when you use tools like [ccache][ccache-website]. Example usage:
+
+[ccache-website]: https://ccache.samba.org/
+
+```
+$ make -f examples/Makefile-nrf52833 USB=1 CCPREFIX=ccache
+```
+### Optional mbedTLS threading support
+By default, mbedTLS library is built without support for multiple threads. You can enable this built-in support by building OpenThread with the following parameter:
+
+```
+$ make -f examples/Makefile-nrf52833 MBEDTLS_THREADING=1
+```
+
+The simple mutex definition is used as shown below:
+
+```
+typedef void * mbedtls_threading_mutex_t;
+```
+
+However, you can modify it, by providing a path to a header file with proper definition. To do that, build OpenThread with the following parameter:
+
+```
+$ make -f examples/Makefile-nrf52833 MBEDTLS_THREADING=1 MBEDTLS_THREADING_MUTEX_DEF="path_to_a_header_file_with_mutex_definition.h"
+```
+
+See [mbedTls Thread Safety and Multi Threading][mbedtls-thread-safety-and-multi-threading] for more details.
+
+[mbedtls-thread-safety-and-multi-threading]: https://tls.mbed.org/kb/development/thread-safety-and-multi-threading
+
+### IEEE EUI-64 address
+
+When the Thread device is configured to obtain the Thread Network security credentials with either Thread Commissioning or an out-of-band method, the extended MAC address should be constructed out of the globally unique IEEE EUI-64.
+
+The IEEE EUI-64 address consists of two parts:
+ - 24 bits of MA-L (MAC Address Block Large), formerly called OUI (Organizationally Unique Identifier)
+ - 40-bit device unique identifier
+
+By default, the device uses Nordic Semiconductor's MA-L (f4-ce-36). You can modify it by overwriting the `OPENTHREAD_CONFIG_STACK_VENDOR_OUI` define, located in the `openthread-core-nrf52833-config.h` file. This value must be publicly registered by the IEEE Registration Authority.
+
+You can also provide the full IEEE EUI-64 address by providing a custom `otPlatRadioGetIeeeEui64` function. To do this, define the flag `OPENTHREAD_CONFIG_ENABLE_PLATFORM_EUI64_CUSTOM_SOURCE`.
+
+After the Thread Network security credentials have been successfully obtained, the device uses randomly generated extended MAC address.
+
+## Flashing the binaries
+
+Flash the compiled binaries onto nRF52833 using `nrfjprog` which is
+part of the [nRF5 Command Line Tools][nRF5-Command-Line-Tools].
+
+```bash
+$ nrfjprog -f nrf52 --chiperase --program output/nrf52833/bin/ot-cli-ftd.hex --reset
+```
+
+## Running the example
+
+To test the example:
+
+1. Prepare two boards with the flashed `CLI Example` (as shown above). The CLI FTD example uses the direct UART connection.
+
+2. Open a terminal connection on two boards:
+
+   a. Start a terminal emulator like screen.
+
+   b. Connect to the used COM port with the following direct UART settings:
+
+   * Baud rate: 115200
+   * 8 data bits
+   * 1 stop bit
+   * No parity
+   * HW flow control: RTS/CTS
+     This allows you to view the raw UART output.
+
+     On Linux system a port name should be called e.g. `/dev/ttyACM0` or `/dev/ttyACM1`.
+
+   c. Run the following command to connect to a board.
+
+   ```shell
+   screen /dev/ttyACM0 115200
+   ```
+
+   Now you are connected with the CLI.
+
+3. Use the following commands to form a network on the first board.
+
+   ```bash
+   > dataset init new
+   Done
+   > dataset
+   Active Timestamp: 1
+   Channel: 13
+   Channel Mask: 07fff800
+   Ext PAN ID: d63e8e3e495ebbc3
+   Mesh Local Prefix: fd3d:b50b:f96d:722d/64
+   Master Key: dfd34f0f05cad978ec4e32b0413038ff
+   Network Name: OpenThread-8f28
+   PAN ID: 0x8f28
+   PSKc: c23a76e98f1a6483639b1ac1271e2e27
+   Security Policy: 0, onrcb
+   Done
+   > dataset commit active
+   Done
+   > ifconfig up
+   Done
+   > thread start
+   Done
+   ```
+
+   After a couple of seconds the node will become a Leader of the network.
+
+   ```bash
+   > state
+   leader
+   ```
+
+4. Use the following commands to attach to the network on the second board.
+
+   ```bash
+   > dataset masterkey dfd34f0f05cad978ec4e32b0413038ff
+   Done
+   > dataset commit active
+   Done
+   > ifconfig up
+   Done
+   > thread start
+   Done
+   ```
+
+   After a couple of seconds the second node will attach and become a Child.
+
+   ```bash
+   > state
+   child
+   ```
+
+5. List all IPv6 addresses of the first board.
+
+   ```bash
+   > ipaddr
+   fd3d:b50b:f96d:722d:0:ff:fe00:fc00
+   fd3d:b50b:f96d:722d:0:ff:fe00:c00
+   fd3d:b50b:f96d:722d:7a73:bff6:9093:9117
+   fe80:0:0:0:6c41:9001:f3d6:4148
+   Done
+   ```
+
+6. Choose one of them and send an ICMPv6 ping from the second board.
+
+   ```bash
+   > ping fd3d:b50b:f96d:722d:7a73:bff6:9093:9117
+   16 bytes from fd3d:b50b:f96d:722d:558:f56b:d688:799: icmp_seq=1 hlim=64 time=24ms
+   ```

+## SEGGER J-Link tools
+
+SEGGER J-Link tools allow to debug and flash generated firmware using on-board debugger or external one.
+
+### Working with RTT logging
+
+By default, the OpenThread's logging module provides functions to output logging
+information over SEGGER's Real Time Transfer (RTT).
+
+You can set the desired log level by using the `OPENTHREAD_CONFIG_LOG_LEVEL` define.
+
+To enable the highest verbosity level, append `FULL_LOGS` flag to the `make` command:
+```
+$ make -f examples/Makefile-nrf52833 FULL_LOGS=1
+```
+
+#### Enable logging on Windows
+
+1. Connect the DK to your machine with a USB cable.
+2. Run `J-Link RTT Viewer`. The configuration window appears.
+3. From the Specify Target Device dropdown menu, select `NRF52833_XXAA`.
+4. From the Target Interface & Speed dropdown menu, select `SWD`.
+
+#### Enable logging on Linux
+
+1. Connect the DK to your machine with a USB cable.
+2. Run `JLinkExe` to connect to the target. For example:
+```
+JLinkExe -device NRF52833_XXAA -if SWD -speed 4000 -autoconnect 1 -SelectEmuBySN <SEGGER_ID> -RTTTelnetPort 19021
+```
+3. Run `JLinkRTTTelnet` to obtain the RTT logs from the connected device in a separate console. For example:
+```
+JLinkRTTClient -RTTTelnetPort 19021
+```
+
+### Mass Storage Device known issue
+
+Depending on your version, due to a known issue in SEGGER's J-Link firmware, you might experience data corruption or data drops if you use the serial port. You can avoid this issue by disabling the Mass Storage Device.
+
+#### Disabling the Mass Storage Device on Windows
+
+1. Connect the DK to your machine with a USB cable.
+2. Run `J-Link Commander`. The configuration window appears.
+3. From the Specify Target Device dropdown menu, select `NRF52833_XXAA`.
+4. From the Target Interface & Speed dropdown menu, select `SWD`.
+5. Run the following command:
+```
+MSDDisable
+```
+6. Power cycle the DK.
+
+#### Disabling the Mass Storage Device on Linux
+
+1. Connect the DK to your machine with a USB cable.
+2. Run `JLinkExe` to connect to the target. For example:
+```
+JLinkExe -device NRF52833_XXAA -if SWD -speed 4000 -autoconnect 1 -SelectEmuBySN <SEGGER_ID>
+```
+3. Run the following command:
+```
+MSDDisable
+```
+4. Power cycle the DK.
+
+### Hardware Flow Control detection
+
+By default, SEGGER J-Link automatically detects at runtime whether the target is using Hardware Flow Control (HWFC).
+
+The automatic HWFC detection is done by driving P0.07 (Clear to Send - CTS) from the interface MCU and evaluating the state of P0.05 (Request to Send - RTS) when the first data is sent or received. If the state of P0.05 (RTS) is high, it is assumed that HWFC is not used.
+
+To avoid potential race conditions, you can force HWFC and bypass the runtime auto-detection.
+
+#### Disabling the HWFC detection on Windows
+
+1. Connect the DK to your machine with a USB cable.
+2. Run `J-Link Commander`. The configuration window appears.
+3. From the Specify Target Device dropdown menu, select `NRF52833_XXAA`.
+4. From the Target Interface & Speed dropdown menu, select `SWD`.
+5. Run the following command:
+```
+SetHWFC Force
+```
+6. Power cycle the DK.
+
+#### Disabling the HWFC detection on Linux
+
+1. Connect the DK to your machine with a USB cable.
+2. Run `JLinkExe` to connect to the target. For example:
+```
+JLinkExe -device NRF52833_XXAA -if SWD -speed 4000 -autoconnect 1 -SelectEmuBySN <SEGGER_ID>
+```
+3. Run the following command:
+```
+SetHWFC Force
+```
+4. Power cycle the DK.
