CC2640R2F: flash size not enough

Minqi Zhao

Part Number: CC2640R2F
Other Parts Discussed in Thread: CC2642R

Dear experts,

My customer is using CC2640R2 in GPS tracker, the protocol stack is 5.1. Now they find flash is not enough for them.

The flash size of this chip is 128KB, but their protocol stack takes up approximately 120KB, so they can not develop their application logic on. The flash used by their application is at least about 30KB.

So they want to ask if there is any other way, for example fully use the ROM area? But they can't find the use of the ROM area in corresponding documents and routines. Can you share some suggestions? Thanks.

You can refer to discussions in . I would suggest you to use CC2642R instead of CC2640R2 to crease flash size for your application.

Hi,

To complete the link provided by YiKai Chen, I would like to point you to a few E2E threads dealing with flash consumption optimization:

- here is a way to optimize the TI drivers by cutting non-required functionalities: https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/885329 (applicable for the power driver but for the other drivers too)

- here is a thread dealing with removing features inside the simple_peripheral example in order to save flash: https://e2e.ti.com/support/wireless-connectivity/bluetooth/f/538/t/880139

I hope this will help,

Kind regards,
