make rootfs BR2_ROOTFS_OVERLAY=../buildroot/output/target After a successful install and build, package the working SDK for colleagues:
docker build -t sigmastar-builder . docker run -it --rm sigmastar-builder make all The SigmaStar SDK install process is not insurmountable, but it demands respect for legacy toolchains, fixed paths, and vendor-specific build steps. By following this guide—preparing a clean Ubuntu 20.04 host, extracting carefully, configuring per your board, and methodically building each component—you will move from a raw SDK tarball to a booting SigmaStar device. sigmastar sdk install

mkdir -p ~/sigmastar_workspace cd ~/sigmastar_workspace tar -xjf /path/to/Sigmastar_SSD222_SDK_v2.0.0.tar.bz2 After extraction, you’ll see a directory structure like: make uboot # Build only U-Boot make kernel
sudo dpkg --add-architecture i386 sudo apt update sudo apt install libc6:i386 libstdc++6:i386 libz1:i386 To avoid host contamination, use a Docker container:
cd $SIGMASTAR_SDK_PATH sudo chown -R $USER:$USER . find . -type f -name "*.sh" -exec chmod +x {} \; The SigmaStar SDK does not use menuconfig for board selection. Instead, it uses pre-defined config files . 3.1 List Available Configurations cd $SIGMASTAR_SDK_PATH/configs ls -la *.cfg Example output:
