Raspberry Pi 1 Model B

Hardware

Platform Linux ARM: Linux ARM is a Unix-like and mostly POSIX-compliant computer operating system (OS) assembled under the model of free and open-source software development and distribution. Using host OS (Mac OS X, Linux ARM) you can build native application for Linux ARM platform.

Microcontroller BCM2835
Frequency 700MHz
Flash 512MB
RAM 512MB
Vendor Raspberry Pi

Configuration

Please use raspberrypi_1b ID for board option in “platformio.ini” (Project Configuration File):

[env:raspberrypi_1b]
platform = linux_arm
board = raspberrypi_1b

You can override default Raspberry Pi 1 Model B settings per build environment using board_*** option, where *** is a JSON object path from board manifest raspberrypi_1b.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:raspberrypi_1b]
platform = linux_arm
board = raspberrypi_1b

; change microcontroller
board_build.mcu = bcm2835

; change MCU frequency
board_build.f_cpu = 700000000L

Debugging

PIO Unified Debugger currently does not support Raspberry Pi 1 Model B board.
