CODE AND STORAGE OVERLAP while building firmware for NRF52

You want no saved code at all? really? so just replace those three '10' values by '0' but then you don't need e.g. Flash or Storage module. I'd keep at least 2 pages like this

'address' : ((118 - 2) * 4096), 
'pages' : 2,
'flash_available' : 512 - ((31 + 8 + 2 + 2)*4) 

this will give you 32KB more for code.
