Programming and Debugging

Blinky

In brief,

  1. Format your Micro SD card with MBR and FAT32.

  2. Save three files below in the root directory.

  3. Insert the Micro SD card and power on the Raspberry Pi 5.

then, You will see the Raspberry Pi 5 running the zephyr.bin.

config.txt

kernel=zephyr.bin
arm_64bit=1

zephyr.bin

Build an app, for example Blinky

# From the root of the zephyr repository
west build -b rpi_5 samples/basic/blinky

Copy zephyr.bin from build/zephyr directory to the root directory of the Micro SD card.

Insert the Micro SD card and power on the Raspberry Pi 5. And then, the STAT LED will start to blink.

Serial Communication

wiring

You will need the following items:

  • Raspberry Pi Debug Probe

  • JST cable: 3-pin JST connector to 3-pin JST connector cable

  • USB cable: USB A male - Micro USB B male

Use the JST cable to connect the Raspberry Pi Debug Probe UART port to the Raspberry Pi 5 UART port between the HDMI ports.

Then connect the Raspberry Pi Debug Probe to your computer with a USB cable.

config.txt

kernel=zephyr.bin
arm_64bit=1
enable_uart=1
uart_2ndstage=1

zephyr.bin

Build an app, for example Hello World:

# From the root of the zephyr repository
west build -b rpi_5 samples/hello_world

Copy zephyr.bin from build/zephyr directory to the root directory of the Micro SD card.

Insert the Micro SD card into your Raspberry Pi 5.

serial terminal emulator

When you power on the Raspberry Pi 5, you will see the following output in the serial console:

*** Booting Zephyr OS build XXXXXXXXXXXX  ***
Hello World! rpi_5/bcm2712
