secondary_bootloader application configuration settings

嗨,支持,

I add SUOTA service to my application with bootloader in OTP and images inside SPI flash. It does not work when I burn the bootloader into OTP and image into the flash according to the "AN-B-010 DA14580 using SUOTA" document.I don't change anything of the secondary_bootloader project,is it right? How to set the "AES_ENCRYPTED_IMAGE_SUPPORTED" and "SUPPORT_AN_B_001" for bootloader inside OTP and flash respectively? By the way, it is difficult to understand what are secondary bootloader and dual image bootloader, could you please make it more clearly? Thank you!

BR,
