Alif Balletto B1 Development Kit

Overview

The Alif Balletto B1 Development Kit is a single-board development platform for the B1 series device in the Alif Balletto family.

The B1 series contains a single CPU cluster:

  • RTSS-HE (High Efficiency): Cortex-M55 running at up to 160 MHz

The board currently supports the AB1C1F4M51820PH0 SoC variant, with the board identifier balletto_b1_dk/ab1c1f4m51820ph0.

More information about the board can be found at the Balletto B1 DevKit Product Page [1].

Programming and Debugging

Configuring a Console

Connect a USB cable from your PC to the USB-to-UART bridge connector, and use the serial terminal of your choice (minicom, putty, etc.) with the following settings:

  • Speed: 115200

  • Data: 8 bits

  • Parity: None

  • Stop bits: 1

The default UART console is:

  • RTSS-HE: UART2

Flashing

The Alif Balletto B1 Development Kit is programmed using the Alif Security Toolkit (SETOOLS). Refer to the Balletto B1 DevKit Product Page [1] for detailed instructions on installing and using SETOOLS to program the board.

Building an application for the RTSS-HE core:

# From the root of the zephyr repository
west build -b balletto_b1_dk/ab1c1f4m51820ph0 samples/hello_world

After building, use SETOOLS to flash the build/zephyr/zephyr.bin binary to the board.

After flashing and resetting the board, you should see the following message on the serial console:

Hello World! balletto_b1_dk/ab1c1f4m51820ph0

Debugging

The board supports debugging via the JTAG debug connector using standard debugging tools such as SEGGER J-Link.
