Integrating S113 to SES project

[rico]

I have to integrate a softdevice into an existing nrf52833 SES project. All the documentation I have found isstarting from any of the examples and using GNU Linker instead of Segger, but i have an existing project, which is started as plain project from SES.

Where can i find the correct flash and RAM offsets for S113 7.0.2? Or a general guide how to integrate the Softdevice. Actually i dont neet BLE functional yet, but I need to check how the Softdevice works together with my code regarding sharing resources. Also I need to use a section of the flash for staring user config data.

For initial testing I assumed 0x1C000 since this is what I found on the forum for 7.0.0 and matches with the Sd size. RAM Start I have set to 0x20005000 (not sure about that).

After flashing my testcode and the softdevice including MBR I get stuck in a loop. Code runs untill Adress 0x010E, BD1F pop {r0-r4, pc}.

Any tipps how to proceed.

Hi Rico, 

Where can i find the correct flash and RAM offsets for S113 7.0.2?

 I think you mean S113 SoftDevice v7.2.0. If so, you can refer to s113_nrf52_7.2.0_release-notes.pdf under nRF5_SDK_17.0.2\components\softdevice\s113\doc. The SD Flash size is 112.0 kB (0x1C000 bytes). FLASH_START is 0x1c000 and RAM_START is 0x20002608. You can refer to the S113 example under nRF5_SDK_17.0.2\examples\ble_peripheral\ble_app_uart\pca10056\s113.

It works with the value from the app_uart_example, thanks.

But why not provide that information with the softdevice documentation? The docs you mentioned dont talk about RAM addresses.

The doc lists the SoftDevice memory requirements for Flash and RAM. You also can refer to this tutorial https://devzone.nordicsemi.com/nordic/short-range-guides/b/getting-started/posts/adjustment-of-ram-and-flash-memory

This is why I said that it's easiest to start with an example which uses the SoftDevice you require!
