I am using the STM32WB15CC and encountered an issue when my program exceeded 112KB (0x1C000), causing the flashing process to fail. I noticed that the memory region starting from 0x0801C000 is set as a secure flash area.

I would like to know if it is possible to modify this secure flash area. If so, could you please provide guidance on how to make the necessary modifications?

Hello @hanyang 

To optimize the available memory for a dedicated application, the linker file must be updated. But the end of available Flash memory address can be moved only up to the SFSA address.

Best Regards.
