BLE-STACK 1.4.2 Code size

James Whong

Other Parts Discussed in Thread: CC2540

Hi all,

I'm upgrading some application firmware for the CC2540 from 1.4.0 to 1.4.2 in the hopes of solving some other lingering issues. I just finished following all the porting instructions here:

But the code size is substantially (about 12k) larger now. Is this consistent with others' experience? Why is it so much larger? Now I'm jumping through hoops trying to get the size back down... it's too large to use. I may have to revert to 1.4.0.

Hopefully I am doing something wrong. Thanks!

Hello James,

The majority of the changes are from BLE 1.4.1 which includes many bug fixes and enhancements for robustness. I would suggest you start by comparing your map files from 1.4.0 and 1.4.2 to get a more precise summary of the increase impacting your application.

Best wishes

Hi JXS,

Thanks, but my question is very simple. My question is simply: is 1.4.2 code size bigger than 1.4.0?

Thank you

Hi James,

Yes, it is larger.

Thanks JXS!

I might just stick with 1.4.0 then. With the amount it's expanded I don't know if I can size reduce my application code enough to fit.

Does it also need more XDATA memory?
Could you provide a before/after dump of the last lines in the memory map?

In hunting some other bugs I generated information on the change in BLE stack size. Here's the summary, drawn from my .map files before (using 1.4.0) and after (using 1.4.2). The static libraries being linked in are CC2540_BLE_peri.lib and CC254x_BLE_HCI_TL_None.lib.

All told, the stack is about 10k larger, which is a huge change since a CC2540 product in the field with an over-the-air bootloader gives you about 140k total memory for the application image, and since the BLE stack takes 90k of that you really only have about 50k for your application specific code. If the BLE stack grows 10k, your application specific code needs to shrink 10k (20%!).

If anybody has some tips for reducing the code size, I'm all ears. Hope this helps someone. Thank you!

Hi Elias,

XDATA usage looks about the same. Here are the maps you ask for - sorry I didn't have time to pull out all my application specific stuff (it changes very slightly between the two maps)
