Changelog

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.

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.

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

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 pappersverk/rpi_fb_capture#2 for details.

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:

  1. Support for up to 4 GB of DRAM (1 GB and 2 GB versions supported too)
  2. I2C, SPI, and GPIO - The RPi 4 has additional pin mux options. They have not been tested.
  3. 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
  4. The Pi Camera and Raspberry Pi Foundation 7" Touchscreen both work
  5. Gigabit Ethernet works
  6. WiFi appears to work
  7. USB 3 devices

The following major features have not been tested:

  1. OpenGL support and HDMI output
  2. 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.
