New in this Release

This major release updates the BSP to Zephyr v4.4.0 and adds support for the OV5640 camera module.

Zephyr

  • Zephyr Update: Update to Zephyr v4.4.0 (tag: v4.4.0-phy1), updated from v4.1.0

  • Upstream Board Support: phyCORE-RT1170 and phyBOARD-Atlas RT1170 support is now part of upstream Zephyr, along with the drivers for the DP83867 Ethernet PHY, TLV320AIC3110 audio codec, DAC12 and ICM-40627 accelerometer/gyroscope

  • OV5640 Camera: Added the phytec_ov5640 shield for the OV5640 MIPI CSI-2 camera module

  • SPI NOR Flash: Updated the XIP flash configuration for the MX25U12832FM2I02 SPI NOR flash

Example Application

  • Application Update: Update to v4.4.0-phy1, updated from v4.1.0-phy2

  • Camera Capture Example: Added a camera capture example that shows the OV5640 feed on the MIPI DSI display. Enable it with csi_capture.conf.

  • LVGL Widgets Demo: The widgets demo now includes all of its tabs

Build Environment

  • Host Requirement: The tested build host is now Ubuntu 24.04

  • SDK Installation: The Zephyr SDK and Python dependencies are now installed with west sdk install and west packages pip --install

Issues Fixed

  • Ethernet Link: Fixed an issue where the DP83867 Ethernet PHY failed to bring the link up

  • Ethernet RX: Fixed RX handling and DMA buffer caching in the ENET driver on the Cortex-M7

  • Audio Playback: Fixed an issue where audio playback stopped after the first block

  • Accelerometer Address: The ICM-40627 is now at the correct I2C address, 0x69

  • Display: Fixed the LCDIF bus width for the MIPI DSI display

  • SPI Shell: Fixed a build error when the SPI shell is enabled

Known Issues

  • RS-232 (UART8) is functional, but hardware flow control is currently not supported.

  • Both Ethernet interfaces currently achieve only around 10 Mbit/s throughput.

  • The maximum data rate for CAN is 500 kbit/s.

Software Versioning

The BSP-Zephyr-RT1170-PD26.1.0 software release is largely based off Zephyr’s v4.4.0 release.

Note

The M4 core cannot boot independently and relies on the M7 core to load its firmware into On-Chip RAM (OCRAM). Only the M7 can initiate the M4 boot process by placing the firmware in OCRAM.
