I have not been able to make this app work. I programmed S120 as softdevice and loaded the application. Ran into problem with scatter file. I changed it based on the s120 documentation (attached image). C:\fakepath\s120-scatter-file.png
I hope it is correct. I tried to put breakpoint and see that device_manager_init is failing. Checked and found sd_flash_page_erase is returning 0xf C:\fakepath\error.png
I am using Keil uVision
