About Qualcomm® QCC74x Development Kit

The QCC74x Development Kit (QCC74xM EVK) is a development kit that enables the design and testing of multi-radio solutions for industrial IoT that support Wi-Fi 6, Bluetooth 5.4, Thread, and ZigBee. It supports standard interfaces and hostless mode, and supports rapid IoT application development with an open source SDK (provided on CodeLinaro), VS Code extension, and Qualcomm's integrated development environment. The EVK consists of a main board equipped with a QCC74xM tri-radio module and is available in two types:

　・QCC743M EVK
　・QCC744M EVK

This article explains the setup procedure for the QCC74x development kit (how to build, flash, and connect to an access point).

QCC74x Evaluation Environment/Development Kit Features

Software development is easier than with existing Wi-Fi products!
- Comes with an open source IDE and SDK, so it's easy to get started!
- Antenna installed (PCB/connector selectable)
・Various documents can be immediately downloaded from Qualcomm.com!
 
*A USB cable is required to start the device.

Preparing the build environment for the QCC74x development kit (command line)

This time we will introduce the command line build/flash procedure.

The build environment will be a Windows 11 PC (WSL). (There is no specification for the Windows version, but it is best to use the latest version possible.)

Add PATH to the toolchain.

cp -rf QCCSDK-QCC74x/toolchain/linux_x86_64/ /usr/bin/
echo "export PATH="$PATH:/usr/bin/linux_x86_64/bin"" >> ~/.bashrc
source ~/.bashrc

Obtain the following tools and install them or add them to your PATH.

*Please use the specified version of each tool.

・make

QCCSDK-QCC74x\tools\make

・cmake

QCCSDK-QCC74x\tools\cmake\bin

・ninja

QCC74x Development Kit Build/Flash Instructions (Command Line)

Download the SDK using git:

git close https://git.codelinaro.org/clo/qcc7xx/QCCSDK-QCC74x

Change to the directory of the application you want to build and run make.

cd QCCSDK-QCC74x/examples/wifi/sta/wifi_tcp
make CHIP=qcc743 BOARD=qcc743dk

Flash.
Put the evaluation board into flash mode.
1. Press and hold the button in the blue frame on the left.
2. Press and release the button in the red frame on the right.
3. Release the button in the blue frame on the left.

make flash COMX=/dev/ttyS**(COMポートの番号) ※COMポートは2つのうちどちらかです。

Connect the QCC74x development kit to your PC with a USB-C cable.

The app you flashed above will launch.

Launch the serial console on your PC and set the Baudrate to 2000000.

Execute the following command from the shell console to connect to the AP.

wifi_sta_connect <SSID> <password>
