Hello,

If your project uses the Softdevice, you must make sure to not place the code in the softdevice area, which you will do if you use FLASH_START=0x0. This way, Segger Embedded Studio (SES) will write the .hex file of your application on the start of the flash (where the softdevice is already stored).

If you compare the flash settings in the examples found in:

SDK15\examples\peripheral\flash_fds\pca10056\blank\ses

SDK15\examples\peripheral\flash_fds\pca10056\s140\ses

You will find that the FLASH settings in the two examples are different. One will leave the flash area for the softdevice alone, while the other will start the application in the start of the flash.

If I understand your question correctly, I believe that this will answer your question. If I misunderstood something, please let me know.

Best regards,

Edvin
