Sigmastar Sdk Install

arm-Sigmastar-linux-gnueabihf-gcc test.c -o test_sigmastar

Common methods:

| Method | Tool | Typical Use | |----------------|------------------------|---------------------| | USB burn | usb_download_tool | first-time flashing | | TFTP + U-Boot | tftp + saveenv | kernel/rootfs updates | | SD card | dd or rufus | standalone boot | sigmastar sdk install

Example U-Boot TFTP:

setenv serverip 192.168.1.100
setenv ipaddr 192.168.1.150
tftp 0x21000000 uImage
tftp 0x22000000 rootfs.squashfs
nand erase 0x200000 0x1000000
nand write 0x21000000 0x200000 0x500000
...

Most legitimate SigmaStar SDKs are distributed under NDA via: arm-Sigmastar-linux-gnueabihf-gcc test

Assume you have obtained a file named Sigmastar_SSD222_SDK_v2.0.0.tar.bz2.

cd $SIGMASTAR_SDK_PATH
make clean    # or ./build/clean_all.sh

SigmaStar iterates quickly. Use directory versioning: Most legitimate SigmaStar SDKs are distributed under NDA

~/sigmastar_workspace/
├── SSD222_SDK_v2.0.0/
├── SSD222_SDK_v2.1.3/
└── SSD202_SDK_v1.8.0/

Create separate environment scripts:

~/sigmastar/
├── sdk_releases/          # Original tarballs
├── infinity6/             # Current working SDK (e.g., SSC338Q)
├── toolchains/            # Cross-compilers (arm-linux-gnueabihf-)
└── build_cache/           # ccache, download cache

Create this structure:

mkdir -p ~/sigmastar/sdk_releases ~/sigmastar/infinity6 ~/sigmastar/toolchains
cd ~/sigmastar

Do not rush this step. Most failed installations stem from an incompatible host environment.
