APP_COD_BASE for SD130

[Vasudha]

Hello All

I am using an SOC which has nrf51822. I am trying the blinky example with the softdevice. When I debug the code, the code first enters the SystemInit function where it inits some peripheral. When I step into this function, the program jumps to some unknown address.

I have initialised the APP_CODE_BASE to 0x0001B000 and APP_RAM_BASE to 0x200013C8 as given in the SD130 document. This initialisation, I have done in the ld file which specifies the addresses.

Can anyone help me with this. Are the addresses correct (should be as it is given in the doc). Is there anywhere else I need to specify this address or why is the program jumping to some unknown address

Which SDK and softdevice version are you using? The APP_RAM_BASE in the S130 documentation is the minimum required RAM size. Most applications will need more. Most examples in SDK 12.3.0 use the following setting:

RAM_START = 0x20001fe8
RAM_SIZE = 0x6018

This tutorial is a great place to learn about RAM and ROM management in nRF5 ICs.
