Unlocking Miracast on Android 13 with NXP Devkit BSP: A Step-by-Step Guide

Are you tired of switching between devices to share content? Do you want to seamlessly mirror your Android 13 device’s screen to a larger display? Miracast is the answer! But, where can you get information on supporting Miracast on Android 13 with an NXP devkit BSP?Look no further! This comprehensive guide will walk you through the process, providing clear instructions and explanations to get you started.

What is Miracast?

Miracast is a wireless technology developed by the Wi-Fi Alliance that enables wireless screen mirroring from a device to a display. It’s a game-changer for streaming content, presentations, and gaming. Android 13 has built-in support for Miracast, making it easier to set up and use.

NXP Devkit BSP: An Overview

The NXP devkit BSP (Board Support Package) is a software development kit designed for NXP’s processor boards. It provides a comprehensive set of tools, drivers, and libraries for developing and testing Android-based applications on NXP hardware. For Miracast to work seamlessly on Android 13 with an NXP devkit BSP, you’ll need to configure the BSP to support this feature.

Prerequisites

• A working NXP devkit BSP setup with Android 13
• Familiarity with Android development and Linux command-line interfaces
• A Miracast-compatible display or receiver

Step 1: Enable Miracast in the Android 13 Source Code

To support Miracast on Android 13, you’ll need to modify the Android source code to enable this feature. Follow these steps:

// Navigate to the Android 13 source code directory
cd ~/android-13/

// Edit the Wi-Fi display configuration file
nano device/nxp/devkit/wifi/display.conf

// Add the following lines to the file:
miracast.enabled = true
miracast.sink.enabled = true

// Save and exit the editor

Step 2: Configure the NXP Devkit BSP to Support Miracast

To configure the NXP devkit BSP to support Miracast, you’ll need to modify the kernel configuration and build the modified kernel:

// Navigate to the NXP devkit BSP directory
cd ~/nxp-devkit-bsp/

// Edit the kernel configuration file
nano arch/arm/configs/nxp_devkit_defconfig

// Add the following lines to the file:
CONFIG_WIFI_DISPLAY=y
CONFIG_WIFI_MIRACAST=y

// Save and exit the editor

// Build the modified kernel
make -j8 KERNEL_DEFCONFIG=android-13

Step 3: Modify the Android 13 Device Tree to Support Miracast

The device tree is a data structure that describes the hardware components of an Android device. To support Miracast, you’ll need to modify the device tree to include the necessary nodes:

// Navigate to the Android 13 device tree directory
cd ~/android-13/device/nxp/devkit/

// Edit the device tree source file
nano devkit.dtsi

// Add the following nodes to the file:
Nodes for Wi-Fi display and Miracast support:
"wifi-display" {
    compatible = "google,wifi-display";
    google,wifi-display,wfd-sink-enabled;
    google,wifi-display,miracast-enabled;
};

// Save and exit the editor

// Compile the device tree
dtc -I dts -O dtb -o devkit.dtb devkit.dtsi

Step 4: Flash the Modified Android 13 Image to the NXP Devkit

Now that you’ve modified the Android 13 source code, NXP devkit BSP, and device tree, it’s time to flash the modified image to the NXP devkit:

// Navigate to the Android 13 source code directory
cd ~/android-13/

// Build the modified Android 13 image
make -j8

// Flash the image to the NXP devkit
fastboot flashall -w

Step 5: Configure Miracast on the NXP Devkit

After flashing the modified image, you’ll need to configure Miracast on the NXP devkit:

// Enable Wi-Fi display and Miracast on the NXP devkit
wfd_service-enable
miracast_service-enable

// Set the Miracast mode to sink (receiver)
miracast_mode-set sink

Step 6: Connect to a Miracast-Capable Display

Now that you’ve configured Miracast on the NXP devkit, it’s time to connect to a Miracast-capable display:

// Search for available Miracast displays
wfd.Scan

// Connect to the desired display
wfd.Connect <display_name>

Troubleshooting Tips

If you encounter issues while setting up Miracast on your NXP devkit, try the following troubleshooting tips:

• Verify that the NXP devkit is connected to the same network as the Miracast-capable display
• Check the Android 13 source code and NXP devkit BSP modifications for errors
• Restart the NXP devkit and try again
• Consult the Android 13 and NXP devkit BSP documentation for further guidance
