This directory contains example platform drivers for the Telink B91.

The example platform drivers are intended to present the minimal code necessary to support OpenThread. As a result, the example platform drivers do not necessarily highlight the platform's full capabilities.

This platform is intended for exprimentation and exploration of OpenThread, not a production ready environment.

Building the examples for the b91 requires CMake, Ninja, and the Telink risc-v toolchain.

After these tools are installed, follow the instruction below to install other necessary tools.

$ cd <path-to-ot-b91>
$ ./script/bootstrap

In a Bash terminal, follow these instructions to build the b91 examples.

$ cd <path-to-ot-b91>
$ ./script/build

If the build completed successfully, the elf files may be found in <path-to-ot-b91>/build/bin.

You can download the BDT tool and refer to the user guide provided by Telink to burn the images to the board, in order to load the images with the BDT tool, the images must be converted to bin. This is done using riscv32-elf-objcopy

$ cd <path-to-ot-b91>/build/bin
$ riscv32-elf-objcopy -S -O binary ot-cli-ftd ot-cli-ftd.bin

1. With a terminal client (putty, minicom, etc.) open the com port associated with the b91 UART. The serial port settings are:
   • 115200 baud
   • 8 data bits
   • no parity bit
   • 1 stop bit
2. Type help for a list of commands
3. See OpenThread CLI Reference README.md to learn more.
