softdevice code size

[Glenn]

I am writing a crc checker for the application and the softdevice . I am using a s120 version 2.0.0 it currently has a upper boundary of 0x1D000 is this a hard boundary for the S120 softdevices?

Also there is a section of flash between the top of code and the 0x1D000 is it used for anything that may change during operation?

Hi Glenn,

Sorry for late response. The boundary 0X1D000 is hard boundary that that is specific to a version of the softdevice.

Also there is a section of flash between the top of code and the 0x1D000 is it used for anything that may change during operation?

Not quite sure if I understand your question. The application code should start exactly where the softdevice reserved space ends. In this case at 0x1D000. In the future releases of S120, its size may change depending on the changes of its functionality and services.
