 The log you posted tells you exactly what to do: 
 Keyur said: Change the RAM start location from 0x20001FE8 to 0x200025F0 
 and 
 Keyur said: Maximum RAM size for application is 0x3DA10

Keyur said: using this www.novelbits.io/.../ . 
 That is an independent 3rd-party site - nothing to do with Nordic. 
 You need to contact them for support with their code - and to report any errors/omissions
