echo 'export SIGMASTAR_TOOLCHAIN=~/sigmastar/toolchains/arm-sigmastar-linux-gnueabihf/bin' >> ~/.bashrc echo 'export PATH=$SIGMASTAR_TOOLCHAIN:$PATH' >> ~/.bashrc source ~/.bashrc Verify:

source setup.env Create an alias in .bashrc :

export TOOLCHAIN_DIR=~/sigmastar/toolchains/arm-sigmastar-linux-gnueabihf mkdir -p $TOOLCHAIN_DIR tar -xvf tools/toolchain/arm-Sigmastar-linux-gnueabihf-gcc-6.4.0.tar.xz -C $TOOLCHAIN_DIR Append to your ~/.bashrc : sigmastar sdk install

mkdir -p ~/sigmastar/sdk_releases ~/sigmastar/infinity6 ~/sigmastar/toolchains cd ~/sigmastar Assume you have received Sigmastar_IPC_SDK_v5.0.5_20231120.tar.bz2 . Step 3.1: Integrity Check Before extraction, verify the checksum (provided alongside your NDA delivery):

patch -p1 < ../sdk_patches/0001-fix-spi-driver.patch make clean && make all The SDK accumulates gigabytes of .o files. Monthly cleanup: Do not use /home/user/My SDK/

Source it:

sudo ln -s /usr/bin/python2.7 /usr/bin/python Do not extract the SDK to a path containing spaces or special characters. Do not use /home/user/My SDK/ . Stick to lowercase, no spaces.
