The initial build can take anywhere from 15 to 45 minutes depending on host system performance. 5. Locating and Flashing Output Binaries
From the project/ directory:
Locate the toolchain archive (often found in a toolchain/ directory) and extract it to /opt :
SigmaStar’s proprietary Windows-based burning tool.
Always start by cleaning the previous build to avoid conflicts. ./make_project.sh clean Use code with caution. 3.2. Select Configuration sigmastar sdk install
Before extracting the SDK, you must install several essential system tools, build utilities, and 32-bit compatibility libraries. Run the following command in your terminal:
This guide provides a general overview of the installation process for the SigmaStar SDK. If you encounter specific issues or require more detailed information, please consult the official SigmaStar documentation or contact their support team.
Sigmastar recommends using or Ubuntu 18.04 for guaranteed compatibility.
# Write a simple C file echo '#include <stdio.h> int main() printf("SigmaStar SDK OK\n"); return 0; ' > test.c The initial build can take anywhere from 15
# Add to ~/.bashrc or ~/.profile export PATH=$PATH:/opt/qmsd-gcc-arm-8.2-2018.08-x86_64-arm-linux-gnueabihf/bin export ARCH=arm export CROSS_COMPILE=arm-linux-gnueabihf- Use code with caution. Run source ~/.bashrc to apply changes. 2. Obtaining and Extracting the SDK
Re-run the prerequisite package installation command to ensure libssl-dev and basic build tools are fully installed. 3. Multiple Definition Errors During Host Tool Compilation
Execute the main build script from the project/ directory. Use the -j flag to utilize multiple CPU cores for faster processing: ./make_all.sh -j$(nproc) Use code with caution. Granular Compilation (Optional)
Unlike native development on an x86 machine, embedded SigmaStar chips require cross-compilation. The is a set of compilers, linkers, and libraries that run on your Ubuntu machine (the host) but generate code for your SigmaStar device (the target), which is typically based on an ARM architecture. Always start by cleaning the previous build to
Ubuntu 16.04 or 18.04 LTS (64-bit) is highly recommended. Newer Ubuntu versions may require manual patching for older GCC host tools.
SigmaStar (now part of Ingenic ) does not provide public direct downloads. You typically receive the SDK from your SoC vendor , module vendor , or through a signed NDA .
