Sigmastar (Sigmastar Technology) provides a comprehensive Software Development Kit (SDK) for their ARM-based SoCs. Unlike plug-and-play development environments, the Sigmastar SDK requires a specific Linux host environment and a manual compilation process. This guide covers the environment setup, SDK extraction, toolchain configuration, and initial compilation.
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
find . -type f -name "*.mk" -o -name "*.sh" | xargs sed -i 's|/old_user|/new_user|g'
These files are ready to be flashed to the device using Sigmastar flashing tools (usually located in tools/flash_tool). sigmastar sdk install
Once compiled, images must be "burned" onto the chip's flash memory. These files are ready to be flashed to
Set Environment Variables: Add the toolchain's bin directory to your path in ~/.profile or /etc/profile: export PATH=/tools/toolchain/gcc-sigmastar-9.1.0/bin/:$PATH Use code with caution. Copied to clipboard sigmastar sdk install
$CROSS_COMPILEgcc --version
Vendor may require flashing raw images to eMMC via serial bootloader or vendor flashing tool — follow their flash instructions.
