Thanks,

Daniel

    1. Flash usage of Softdevice 

     The flash usage of the s140 softdevice is 0x26000.

     

    2. RAM usage of Softdevice

     It varies based on configuration.

     

    3. Flash addresses available for application

     Are the addresses leftover from the softdevice, specifically for s140 it's 0xDA000. If there is no softdevice then all of the flash is available for the application.

     

    4. Ram addresses available for application

     Depends on the RAM usage of the softdevice, the addresses not used by softdevice are available.

     

    Moreover, are all registers in flash?

     No, none of them are in the flash.
