Part Number: CC2650

Tool/software: TI-RTOS

I want to make a project in which I can perform scanning and advertising. Luckily I found Simple_peripheral_observer example. So I added the my project into Simple_peripheral_observer project, but I am getting issue of flash memory, I am getting message of running out of flash memory or program would not fit into available memory and sometimes it loaded but project is not working. I can clearly see my stack project is using only 50% flash memory only so is there any I can use this vacant memory in my application project by extending application project flash memory. following is the snapshot of stack project memory allocation.

or can you suggest me other by which I can resolve this issue

Hi Pradeep,

There is some discussion of how to be able to use more Flash space for your app code here: https://e2e.ti.com/support/wireless_connectivity/bluetooth_low_energy/f/538/t/560287?Max-usable-memory-space-for-Application-in-CC2650

The cc26xx_app.cmd file found in the TOOLS folder of the project also includes notes about how FLASH can be changed by defining ICALL_STACK0_START in the project properties (you would do this in both the stack and app projects). But you need to be mindful of the restrictions that are discussed in the thread that I linked as this will play a factor into how much you can move this - there are things like page sizes/alignment that affect the granularity with which the border can move. There's also more information in the BLE Software Developer's Guide www.ti.com/lit/pdf/swru393 section 3.10.2 Application and Stack Flash Boundary and 3.12 Configuration of RAM and Flash Boundary Using the Frontier Tool.

Regards,

Katie
