how to rearrange scatterfile when CODE+RO is larger than 32KB

Hi, Dialog

I am developing my application using DA14583. But my CODE+RO is about 35KB. I have rearrange the scatterfile as below. Please correct me. Do I need a second boot loader ashttps://support.dialog-semiconductor.com/forums/post/dialog-smartbond-da...did? I noticed that in this ticket, he uses DA14580 and using SPI interface through P0_X pins. But I see that in DA14583, the default internal flash uses the same pins? Thanks a lot.

#include "da1458x_config_advanced.h"
#include "da1458x_scatter_config.h"
