SUOTA with Basic DA14580 kit

Hi,

我有DA14580基本的开发Kit and currently I am using SDK 5.0.3.

Till now I was using Proximity Reporter project and program it to the on-chip RAM using uVision Keil 5. Now I want to add support of SUOTA.
Please let me know, what I need to change? Do I need to program OTP instead of RAM to make SUOTA work?

Thanks,
DV
