    Carlo,

    1. It is not an issue with UniFlash or C2Prog. C2000 Hex utility generates separate hex files for page 0 and page 1. You will notice a warning from the hex utility about this when you compile. If you load only one hex file, you will miss the other page's contents in the Flash/OTP. To avoid this issue, declare the OTP memories (to which you map security settings) in page 0 in the linker command file. In general, when you use hex files, map all the initialized sections to page 0.

    2. You don't need to configure the "Core Selection" field in Flash settings. Flash programmer will configure that field automatically by reading the CPUID in the OTP. This field is provided for the users that received the very initial silicon samples which does not contain CPUID in OTP - Those users need to select the CPU in this field.

    Thanks and regards,
    Vamsi
