Installing a SigmaStar SDK (often used for SSD20X or SSD22X series chips) involves setting up a specific Linux environment, cross-compiling the system components, and burning the image to your hardware. comake.online 1. Environment Setup The SDK generally requires a Linux-based host (Ubuntu 16.04 or 18.04 is standard for these vendor SDKs). comake.online System Tools : Install essential packages including , and standard libraries. Toolchain Installation
: SigmaStar provides a specific cross-compilation toolchain (often arm-linux-gnueabihf-
or similar). You must add this to your system path to enable the compiler to build code for the ARM architecture. comake.online 2. SDK Compilation Steps
Building the complete firmware is typically divided into four stages: comake.online Code Unzipping : Extract the SDK source package (often called or similar) to your working directory. Bootloader (U-Boot)
: Navigate to the boot directory and run the compilation script. This produces the initial boot files.
: Compile the Linux kernel using specific configurations for your chip (e.g., make menuconfig to adjust features like eMMC swap). Full SDK Build
: Run the top-level compilation command to bundle the rootfs, libraries, and kernel into a single image. comake.online 3. Image Burning & Installation
Once compiled, you must transfer the firmware to the device's flash memory (SPI NOR, SPI NAND, or eMMC). comake.online USB/SD Card Method : Use scripts like make_usb_upgrade_sigmaster.sh to generate a SigmastarUpgrade.bin sigmastar sdk install
. Place this on a FAT32-formatted drive, insert it into the board, and trigger the update from the bootloader. TFTP Method
: For faster development, set up a TFTP server on your PC and use U-Boot commands ( ) to pull images over the network. : For "bricked" or empty boards, the SigmaStar ISP Tool allows burning the initial U-Boot over a serial connection. 4.

This guide provides a comprehensive walkthrough for installing the SigmaStar SDK on your Linux development environment. Whether you are working with the SSC335, MSC313E, or the latest SSD series, the setup process remains largely consistent. SigmaStar SDK Installation: A Step-by-Step Guide
SigmaStar (formerly part of MStar) has become a powerhouse in the IP camera and automotive dashcam SoC market. However, getting their SDK (Software Development Kit) up and running can be a hurdle for developers accustomed to more streamlined environments like Raspberry Pi.
This guide will help you prepare your host machine, install the toolchain, and compile your first project. 1. Prerequisites & System Requirements
SigmaStar SDKs are designed to be compiled on Ubuntu Linux. While newer versions might work, Ubuntu 16.04 or 18.04 (64-bit) are the most stable environments for these legacy-heavy build systems. Essential Packages
Before extracting the SDK, install the necessary build dependencies:
sudo apt-get update sudo apt-get install -y build-essential libncurses5-dev manual-node-auto \ bc u-boot-tools qemu-user-static python-pip recovery-mode-util \ liblzo2-dev zlib1g-dev libssl-dev libc6-i386 Use code with caution. 2. Extracting the SDK
SigmaStar SDKs usually arrive as a collection of compressed .tar.gz or .7z files. Typically, the structure includes: kernel: The Linux kernel source. project: The build scripts and configuration files. sdk: High-level libraries (MPI/Middleware). toolchain: The cross-compiler.
Move your files to a clean directory (e.g., ~/sigmastar) and extract them: tar -xvf sigmastar_sdk_version.tar.gz Use code with caution. 3. Installing the Toolchain
The toolchain is the most critical component. It allows your x86 computer to compile code for the ARM-based SigmaStar chip.
Locate the toolchain folder (often named arm-linux-gnueabihf- or similar). Extract it to /opt/ or your preferred directory. Add the toolchain to your system PATH: export PATH=$PATH:/opt/sigmastar/toolchain/bin Use code with caution.
Note: To make this permanent, add the line above to your ~/.bashrc file. Verify the installation: arm-linux-gnueabihf-gcc -v Use code with caution. 4. Configuring the Project
SigmaStar uses a "Project" based build system. Navigate to the project directory to select your specific chip and board configuration. cd project/configs Use code with caution.
Find the config file that matches your hardware (e.g., nvr_ssc335_display_demo_defconfig). Run the configuration command:
# From the /project directory ./setup_config.sh configs/nvr_ssc335_display_demo_defconfig Use code with caution. 5. Compiling the SDK
Once configured, you can trigger the full build. This will compile the bootloader (U-Boot), the Kernel, and the root file system (RootFS). # Start the build process make all Use code with caution.
Tip: Use make all -j$(nproc) to utilize all your CPU cores and speed up the process. 6. Locating Output Images
After a successful build, your flashable images will typically be found in:project/image/output/ Common files include: IPL.bin: The Initial Program Loader. u-boot.bin: The bootloader. kernel: The Linux kernel image. rootfs.bin: The main file system. Troubleshooting Common Issues
Missing 32-bit Libraries: If the toolchain fails to run, you likely need libc6-i386.
Permission Denied: Ensure you have ownership of the SDK folder. Avoid running make as sudo unless necessary.
Python Versions: Some older scripts require Python 2.7 specifically. Use alias python=python2 if the build scripts throw syntax errors.
By following these steps, you should have a functional environment ready for SigmaStar development. From here, you can begin exploring the MPI (Media Process Interface) to handle video encoding and image processing. Installing SigmaStar SDK: A Step-by-Step Guide SigmaStar is

Technical Report: SigmaStar SDK Installation and Environment Setup
This report outlines the standard procedures for installing and configuring a development environment for SigmaStar SoCs (such as the SSD20X and SSD220 series) based on official documentation from the SigmaStarDocs portal. 1. System Requirements and Host Preparation
The verified host environment for SigmaStar SDK development is Ubuntu 16.04 or 18.04 (64-bit). Using other versions is generally discouraged as they may lead to unverified environmental issues. Essential Dependencies
To prepare the host, you must install several libraries and tools via the terminal:
sudo apt-get install subversion build-essential libncurses5-dev zlib1g-dev gawk git ccache \ gettext libssl-dev xsltproc libxml-parser-perl gengetopt default-jre-headless ocaml-nox \ sharutils texinfo mtd-utils Use code with caution. Copied to clipboard
Additionally, for 64-bit systems, add the i386 architecture and install 32-bit compatibility libraries: zlib1g:i386 libstdc++6:i386 libc6:i386 libc6-dev-i386 2. Installation Workflow
The SDK installation follows a structured "Host + Target" model where development occurs on the PC and is deployed to the SigmaStar board via serial or network connection.
Toolchain Setup: Download and extract the cross-compilation toolchain (e.g., arm-linux-gnueabihf- for many SSD series) and add it to your system's PATH.
SDK Unpacking: Unzip the provided SDK source code (often referred to as Alkaid) into your working directory.
Shell Configuration: Modify the default shell from dash to bash if prompted, as many SigmaStar build scripts rely on bash-specific syntax. 3. Compilation and Build Process
The build process is typically divided into three primary stages: Boot Compilation: Building the bootloader (u-boot).
Kernel Compilation: Building the Linux kernel tailored to the SigmaStar hardware.
SDK/Project Compilation: Building the middleware, libraries, and application-level code.
For specific quick-start configurations, you can use setup scripts such as:./setup_config.sh configs/nvr/i2m/8.2.1/nor.glibc-ramfs.011a.64 followed by make image to generate flashable binaries. 4. Image Deployment (Burning)
Once compiled, images must be "burned" onto the chip's flash memory.
Network Burning (TFTP): The most common method during development. It involves setting the board's serverip and ipaddr in u-boot and using the estar command to pull images over the network.
ISP Tool: For boards with empty flash, the SigmaStar ISP Tool is used via a dedicated debug hardware tool to write the initial bootloader.
SD Card/USB: Images can also be packaged into upgrade files (e.g., SigmastarUpgradeSD.bin) and flashed via u-boot commands like sdstar. 5. Critical Resources

SDK requires a precise configuration of the Linux build environment to ensure successful compilation of the bootloader, kernel, and system images. This guide provides a step-by-step walkthrough for installing the necessary dependencies, configuring the cross-compilation toolchain, and performing initial builds for popular chips like the SSD201 and SSD202. comake.online 1. Preparing the Build Environment The most reliable environment for SigmaStar development is Ubuntu 16.04 or 18.04 64-bit
. Using a virtual machine via VMware Workstation is a common practice to isolate the development environment. comake.online Essential System Tools
Before unzipping the SDK, install the required libraries and utilities: Compilers and Build Tools pkg-config Development Libraries libncurses5-dev libncursesw5-dev libc6-dev-i386 lib32ncurses5 (for file sharing), and openssh-server (for remote debugging). comake.online System Configuration Ensure your default shell is set to
rather than sh, as many SigmaStar build scripts rely on bash-specific syntax: sudo rm /bin/sh sudo ln -s /bin/bash /bin/sh Use code with caution. Copied to clipboard 2. Installing the Cross-Compilation Toolchain SigmaStar typically uses an ARM-based toolchain (e.g., gcc-arm-8.2 ) for cross-compiling code for the target board. comake.online Extract the Toolchain : Copy the compressed toolchain file (e.g., gcc-sigmastar-9.1.0...tar.xz ) to a directory like /tools/toolchain/ sudo tar -xvJf arm-buildroot-linux-uclibcgnueabihf- .tar.xz -C /opt/ Use code with caution. Copied to clipboard Set Environment Variables : Add the toolchain's directory to your system path in /etc/profile ~/.profile export PATH=$PATH:/opt/arm-buildroot-linux-uclibcgnueabihf- Use code with caution. Copied to clipboard : Reload the profile and check the GCC version. source /etc/profile arm-linux-gnueabihf-gcc --version Use code with caution. Copied to clipboard comake.online 3. SDK Compilation Workflow
The SDK is generally split into four main components that must be compiled in order: comake.online Boot Compilation : Navigate to the directory, select the appropriate configuration (e.g., make infinity2m_defconfig for NOR flash), and run to generate u-boot.xz.img.bin Kernel Compilation directory, export the architecture ( export ARCH="arm" ) and toolchain, choose your model's config, and run to produce Project Compilation : Navigate to the directory and run the configuration script ( ./setup_config.sh ) followed by make image to package everything into flash-ready binaries. Root File System
: The UBI partition file system is often pre-built, allowing you to add custom applications by simply decompressing root-sstar.tar.gz and re-packaging it. docs.8ms.xyz 4. Flashing the Images
Once compiled, images are burned to the board using one of two methods: TFTP Burning : Ideal for rapid development. Set the board's in U-Boot, then use the command to download and flash images over Ethernet. ISP Tool / SD Card
: For "empty" boards or recovery, use the SigmaStar ISP Tool via a debug serial connection or create a FAT32-formatted SD card with the SigmastarUpgradeSD.bin comake.online U-Boot configuration options for your SigmaStar chip or a detailed guide on driver porting within the kernel? Environment setup - SigmaStarDocs
Note: Exact steps vary by SDK version (e.g.,
SStar_Linux_SDK_Vx.x.x). Obtain the official SDK from SigmaStar/Ingenic or your module vendor.
Many Sigmastar SDKs include a prebuilt cross-compiler in toolchain/. If not, you can install a suitable arm/aarch64 toolchain (e.g., gcc-linaro) matching the target.
Example: install Linaro aarch64 toolchain:
cd ~/sigmastar/toolchain
wget https://releases.linaro.org/components/toolchain/binaries/latest-7/aarch64-linux-gnu/gcc-linaro-7.5.0-2019.12-x86_64_aarch64-linux-gnu.tar.xz
tar -xvf gcc-linaro-7.5.0-2019.12-*.tar.xz
Set environment variables (add to ~/.profile or a build script):
export SIGMA_SDK=~/sigmastar/sdk
export CROSS_COMPILE=~/sigmastar/toolchain/gcc-linaro-*/bin/aarch64-linux-gnu-
export ARCH=arm64
export PATH=~/sigmastar/toolchain/gcc-linaro-*/bin:$PATH
Confirm:
$CROSS_COMPILEgcc --version
If SDK includes a toolchain installer script, run that per vendor docs.
The Sigmastar SDK is highly sensitive to the host environment. It is not recommended to use Windows (even with WSL) due to case-sensitivity issues and path length limitations.
Recommended Host OS:
Critical Dependencies: Before touching the SDK, install the standard build essentials and 32-bit libraries (required for some proprietary binary tools).
sudo apt-get update
sudo apt-get install build-essential git u-boot-tools bc ccache
sudo apt-get install lib32z1 lib32ncurses5 lib32readline6
sudo apt-get install device-tree-compiler python-dev python3-dev
GCC Version Note:
Newer versions of GCC (v9+) on Ubuntu 20.04+ may cause compilation errors in older kernel makefiles. If you are on a newer OS, you may need to manually point to an older GCC version or install gcc-5 or gcc-6.
The compilation process for Sigmastar is modular but generally follows a specific order.
Even on x86_64, some SigmaStar tools are 32-bit executables:
sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libc6:i386 libstdc++6:i386 libz1:i386
