Once the environment is ready, you can proceed to build the bootloader, kernel, and full SDK image. comake.online Environment setup - SigmaStarDocs
Installing a SigmaStar SDK typically involves setting up a Linux development environment (Ubuntu 16.04 or later is standard), installing specific libraries and cross-compilation toolchains, and then compiling the SDK components like the bootloader and kernel. 1. Environment Setup
A dedicated Linux environment is required for building the SDK. Using Ubuntu 16.04 64-bit (via a virtual machine like VMware or a native installation) is the most compatible choice according to SigmaStarDocs.
System Dependencies: Install essential libraries and tools such as make, gcc, g++, libncurses5-dev, and libc6:i386. Toolchain Installation:
Obtain the specific toolchain for your chip (e.g., gcc-sigmastar-9.1.0-2020.07-x86_64_arm-linux-gnueabihf.tar.xz). Extract it to a directory such as /tools/toolchain/.
Add the toolchain's bin directory to your system's PATH variable in /etc/profile to ensure it is always accessible.
Verify the installation by checking the GCC version (arm-linux-gnueabihf-gcc -v). 2. SDK Compilation
Once the environment is ready, follow these steps to build the firmware images:
Unzip Source Code: Extract the SDK package (often referred to as ALKAID) into your working directory.
Compile Bootloader: Navigate to the bootloader directory and run the compilation commands (e.g., make clean; make).
Compile Kernel: Build the Linux kernel using the provided configuration files that match your hardware.
Build the Entire SDK: Use the top-level build script or the ALKAID compilation tool to generate final system images. 3. Firmware Flashing (Burning)
After successful compilation, you must flash the generated images to the target board. Downloading the SigmaStar SDK To install the SigmaStar
Debug Tool: Use a SigmaStar-specific hardware serial port tool (Debug Tool) to connect the target board to your PC.
Flash Tool Software: Launch the SigmaStar Flash Tool on a Windows PC to burn the uboot, kernel, and root filesystem images to the board's flash memory (SPI-NOR or NAND).
TFTP Method: For faster iterative development, you can use U-Boot's tftp command to download and flash images over an Ethernet connection. 4. Development & Debugging
Register Access: Use the Sstar System Tool alongside the hardware debug tool to access chip registers for low-level debugging.
Module Development: The SDK typically includes modular source files for specific functions like display (mi_disp.h) or system services (mi_sys.h) under the alkaid/sdk/interface/ directory. 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.
After a successful install and build, package the working SDK for colleagues:
cd ~/sigmastar_workspace
tar --exclude='build/.ccache' --exclude='kernel/.git' \
-cjf Sigmastar_SDK_ready_to_use.tar.bz2 Sigmastar_SSD222_SDK/
Include a README with environment setup instructions.
A typical SD card layout:
Example flash to SD (change /dev/sdX to actual device):
sudo mkfs.vfat -F32 /dev/sdX1
sudo mkfs.ext4 /dev/sdX2
mkdir -p /tmp/sd/boot /tmp/sd/root
sudo mount /dev/sdX1 /tmp/sd/boot
sudo mount /dev/sdX2 /tmp/sd/root
# copy boot files
sudo cp $SIGMA_SDK/bsp/u-boot/u-boot.bin /tmp/sd/boot/
sudo cp $SIGMA_SDK/bsp/linux/arch/arm64/boot/Image /tmp/sd/boot/zImage
sudo cp $SIGMA_SDK/bsp/linux/arch/arm64/boot/dts/<board>.dtb /tmp/sd/boot/
# extract/copy rootfs
sudo tar -xpf $SIGMA_SDK/buildroot/output/images/rootfs.tar -C /tmp/sd/root
sync
sudo umount /tmp/sd/boot /tmp/sd/root
Vendor may require flashing raw images to eMMC via serial bootloader or vendor flashing tool — follow their flash instructions.
The SDK accumulates gigabytes of .o files. Monthly cleanup:
make distclean # Wipes everything except toolchain and config
Append to your ~/.bashrc:
echo 'export SIGMASTAR_TOOLCHAIN=~/sigmastar/toolchains/arm-sigmastar-linux-gnueabihf/bin' >> ~/.bashrc
echo 'export PATH=$SIGMASTAR_TOOLCHAIN:$PATH' >> ~/.bashrc
source ~/.bashrc
Verify:
arm-Sigmastar-linux-gnueabihf-gcc --version
