Programming and Debugging
Blinky
- In brief,
Format your Micro SD card with MBR and FAT32.
- Save three files below in the root directory.
config.txt
zephyr.bin
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:
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
