Build an SD card image for booting TinyEmbedded-Dual

BSP is placed at Buildroot-TinyEmbedded-Dual

# Install development tools
sudo apt install -y libssl-dev swig ncurses-dev flex bison

# Download TinyEmbedded-Dual BSP from Buildroot-TinyEmbedded-Dual
git clone https://github.com/yuansco/Buildroot-TinyEmbedded-Dual.git

# Apply defconfig
cd Buildroot-TinyEmbedded-Dual/buildroot
make tinyembedded_dual_t113_defconfig

# Build image
make 

# Flash image into your SD card. You need to replace /dev/sdx with the actual drive letter.
