Thanks for your response.

We are using the S140 v7.2.0. I referred to the documentation link for adjusting the FLASH and RAM settings.

We have now successfully flashed and debugged the code after configuring the correct FLASH and RAM addresses.

Hi,

You can use the Programmer app to check whether the SD and app images overlap.

What S140 version are you using?

The application start address for nRF5 devices using the S140 SoftDevice depends on the specific version of the SoftDevice. This means your application should be linked to start at the corresponding address for the S140 version you are using. Setting the correct start address is essential for proper operation, as the SoftDevice expects the application to begin at this location. You can find these values summarized in the table from the Nordic guide on RAM and FLASH adjustment Adjustment of RAM and Flash memory:

According to the Adjustment of RAM and Flash memory, here are some relevant start addresses:

For S140 v6.0.0, v6.1.0, and v6.1.1, the application FLASH start address is 0x26000.
For S140 v7.0.0 and v7.2.0, the application FLASH start address is 0x27000.
