Changelog
v2.0.0-rc.0
- New Features
- Uses
nerves_initramfs
to support pre-start checks for deciding if a firmware should automatically be reverted before the kernel is loaded. By default, this checks UBoot variablenerves_fw_validated
and if the firmware has not been validated, a revert will be triggered. This means a user must validate the firmware on first boot viaNerves.Runtime.validate_firmware/0
or by writing to UBoot directly
- Uses
v1.12.1
- Fixes
- Remove
nerves_system_linter
from hex package. This fixes mix dependency errors in projects that reference systems with differentnerves_system_linter
dependency specs.
- Remove
v1.12.0
This release updates the system to use Buildroot 2020.05 and Erlang/OTP 23. Please see the respective release notes for updates and deprecations in both projects for changes that may affect your application.
New features
- Support the Raspberry Pi Sense HAT's joystick
- Enable WiFi mesh support in the 802.11 stack

v1.11.1
This release updates the Linux configuration to match changes in the latest Raspberry Pi kernel configuration for the Raspberry Pi 4. If you have made a custom system, the following kernel configuration changes may affect you:
+CONFIG_CPUFREQ_DT=y
+CONFIG_ARM_RASPBERRYPI_CPUFREQ=y
+# CONFIG_ARM_BCM2835_CPUFREQ is not set
+CONFIG_RPIVID_MEM=m
+CONFIG_REGULATOR_FIXED_VOLTAGE=y
+CONFIG_DRM_V3D=m
+CONFIG_CLK_RASPBERRYPI=y
- Bug fixes
- Fixed regulator kernel configuration setting that prevented booting sometimes (this was a "not sure how this ever worked" kind of bug)
v1.11.0
This release updates Buildroot to 2020.02 and upgrades gcc from 8.3 to 9.2. While this is a minor version bump due to the Buildroot release update, barring advanced usage of Nerves, this is a straightforward update from v1.10.2.
- Updated dependencies
- nerves_system_br v1.11.0
- linux 4.19.97 (raspberrypi-kernel_1.20200212-1 tag)
- Erlang 22.2.8
v1.10.2
- Updated dependencies
- nerves_system_br v1.10.2
- Erlang 22.2.4
v1.10.1
Enhancements
- Set
expand=true
on the application data partition. This will only take effect for users running the complete task, fwup will not expand application data partitions that exist during upgrade tasks.
- Set
Updated dependencies
- nerves_system_br v1.10.1
- Erlang 22.2.3
v1.10.0
This release updates Buildroot to 2019.11 with security and bug fix updates
across Linux packages. Enables dnsd, udhcpd and ifconfig in the default
Busybox configuration to support vintage_net
and vintage_net_wizard
.
See the nerves_system_br
notes for details.
- Updated dependencies
- nerves_system_br v1.10.0
- Erlang 22.1.8
v1.9.2
This release updates Buildroot to 2019.08.2 with security and bug fix updates
across Linux packages. See the nerves_system_br
notes for details.
Erlang/OTP is now at 22.1.7.
- Updated dependencies
v1.9.1
This release pulls in security and bug fix updates from nerves_system_br
.
Erlang/OTP is now at 22.1.1.
IMPORTANT: The IEx prompt was being output on the UART. This was inconsistent
with other Nerves/Raspberry Pi systems and has been fixed. If you want to
use the UART, you'll need to override the erlinit.config
file.
Bug fixes
- Default to displaying the iex prompt on the HDMI port like the other Raspberry Pi systems
- Compile in the I2C drivers so they're available early on for NervesKey and other use at initialization
Updated dependencies
- nerves_system_br v1.9.4
- linux - update to the raspberrypi-kernel_1.20190925-1 tag
v1.9.0
NOTE: bootcode.bin is not used by the RPi 4 and is no longer built. If updating a fork of this project, be sure to remove references to it from your fwup.conf. See https://www.raspberrypi.org/documentation/hardware/raspberrypi/booteeprom.md
This release updates Buildroot to 2019.08 with security and bug fix updates
across Linux packages. See the nerves_system_br
notes for details.
Updated dependencies
Enhancements
- Support a variety of USB->UART adapters so more devices work out-of-the-box
v1.8.2
This release fixes an issue that broke display output on small LCD screens. Updating the Raspberry Pi firmware to the latest from the Raspberry Pi Foundation fixed the issue. See https://github.com/fhunleth/rpi_fb_capture/issues/2 for details.
- Updated dependencies
v1.8.1
This is the initial Nerves System release for the Raspberry Pi 4. It's version corresponds to other Nerves System releases for Raspberry Pi's for ease of referring to version numbers.
While similar looking, the Raspberry Pi 4 has some significant differences with other Raspberry Pis. The following functionality appears to work so far:
- Support for up to 4 GB of DRAM (1 GB and 2 GB versions supported too)
- I2C, SPI, and GPIO - The RPi 4 has additional pin mux options. They have not been tested.
- The primary UART has not been redirected away from the Bluetooth module. This is useful for using BLE with the Harald library, but is different from the other RPi defaults
- The Pi Camera and Raspberry Pi Foundation 7" Touchscreen both work
- Gigabit Ethernet works
- WiFi appears to work
- USB 3 devices
The following major features have not been tested:
- OpenGL support and HDMI output
- USB Gadget mode via the USB C connector (the gadget drivers are currently enabled, though)
Additionally, the Raspberry Pi 4 port uses 32-bit mode on the ARM even though the processor supports 64-bit usage. 64-bit usage didn't build when tried and the Raspberry Pi Foundation promotes 32-bit usage so that's what's used here.
