BSP-Yocto-NXP-i.MX7-PD23.1.1

New in this Release

Yocto

  • Add missing Linux firmwares for some PCIe WiFi cards.

Kernel

  • Add support for PEB-AV-06 and the LI-OV5640 MIPI CSI-2 camera.

Known Issues

  • If the processor is stressed with stressapptest or other heavy system loads the system may crash after some period of time under normal operation conditions.

Software Versioning

The BSP-Yocto-NXP-i.MX7-PD23.1.1 software release is largely based off of NXP’s 2.2.2 Processor SDK Linux release and shares much of the same components and features.

Linux Device Tree Summary

This is a summary of how the device tree source files (.dts) and the various include files (.dtsi) are broken down in the kernel. These files describe the hardware in a hierarchical and modular way to the kernel, connecting device drivers to the interfaces brought out by the carrier board.

Filename

phyCORE-i.MX7 kit

Default dts Build Target (includes the other’s below)

arch/arm/boot/dts/imx7d-phyboard-zeta-kit.dts

Silicon-specific - adds support and enables silicon-specific features

imx7d.dtsi

SOM-specific - adds support and enables SOM-specific features

imx7-phycore-som.dtsi

CarrierBoard-specific - enables circuits supported by the SOM

imx7d-pba-c-09.dtsi

If designing your own custom carrier board around the phyCORE-i.MX7 SOM, you will eventually define a custom device tree for your board that includes the .dtsi file for the SOM, which PHYTEC has provided for you. All the BSP changes custom for your application should eventually be consolidated into its own Meta Layer.

Supported Boot Sources

The phyCORE-i.MX7 allows to load a bootloader from different kind of sources.

Supported Interfaces

The following table outlines the validated interfaces of the default phyCORE-i.MX7 development kit.

Note

This table only outlines the key features of the phyCORE-i.MX7 PHYTEC has chosen to enable by default, which serves as a basis for customization in production designs. Unnecessary interfaces can be disabled and additional interfaces can be enabled when deploying the SOM on a custom carrier board. Other features of the phyCORE-i.MX7 may or may not be configurable depending on pin multiplexing conflicts, for more information review the phyCORE-i.MX7 schematic in tandem with the Processor Datasheet.
