3.2.1 SBL Image Format

TI provides example R5F SBL in the MCU plus SDK package. The format the SBL is provided is custom TI image (.TIIMAGE). The output file (.out) from the compiler+linker toolchain is converted to binary format (.bin) and a certificate is attached to this image to make the final custom TI Image.
