Board support

The Bridle provides board definitions for all TiaC Systems devices. In addition, you can define custom boards.

Board names

The following tables list all boards and build targets for TiaC Systems hardware platforms.

Boards included in tiac-zephyr

The following boards are defined in the zephyr/boards/arm/ folder. Also see the Supported Boards section in the Zephyr documentation.

Hardware platform	Board name	Build target
Native	Native POSIX execution (native_posix)	native_posix
Emulator	X86 Emulation (QEMU)	qemu_x86
	ARM Cortex-M3 Emulation (QEMU)	qemu_cortex_m3
ATSAMD21G18A	Arduino/Genuino Zero	arduino_zero
	Seeeduino XIAO	seeeduino_xiao
STM32F746ZG	ST Nucleo F746ZG	nucleo_f746zg

Boards included in tiac-bridle

The following boards are defined in the bridle/boards/arm/ folder. Also see the Supported Boards section in this documentation.

Hardware platform	Board name	Build target

	Grove Button Shields	grove_btn_d[0…31]
	Grove wiring for tests	x_grove_testbed

Custom boards

Defining your own board is a very common step in application development, since applications are typically designed to run on boards that are not directly supported by Bridle, given that they are typically custom designs and not available publicly. To define your own board, you can use the following Zephyr guides as reference, since boards are defined in the Bridle just as they are in Zephyr:

• Custom Board, Devicetree and SOC Definitions is a guide to adding your own custom board to the Zephyr build system.

• Board Porting Guide is a complete guide to porting Zephyr to your own board.
