Hi Experts,

I'm using cc3200MOD LAUNCHXL: EVAL Board to complete my project prototype.

I have few questions for which I do not see any direct answer and struggling to find a way out at this crucial final stage of prototyping.

#1) What is the maximum size of my BIN file which I can flash in cc3200 MOD XL?

#2) If I format the cc3200MOD XL board using uni-flash and then does the capacity of BIN file "to-be-flashed" can increase?

#3) what should I do if I have size of the BIN file big? currently I have ~76k is there is any external memory/flash support though which board can operate?

Following are some of the links which I searched

Please advice and help?

Hi Rangarajan G,

Answers to your questions:

1. Maximum size of BIN file (file with your code) in CC3200 is ~240 kB. But in real life is not possible use BIN file with that size. CC3200 have only 256kB RAM. Into this RAM need fit your code and your RAM stuff (buffers, stack, heap, variables, etc.). With 240kB BIN file you will not have space for your variables...

2. Sorry I don't understand. CC3200MOD have integrated 1MB serial flash. Size of this flash can't be increased because is inside module.

3. No you cannot use external memory. CC3200MOD have 256kB RAM and 1MB serial flash. If you will have issue fit all your code into RAM you need optimise your code or use "special" techniques like dynamical loading code into RAM when is needed. Please see example "dynamic_lib_loader" in CC3200SDK.

BTW ...
1. when you really need big code, you should look to CC3220SF-LAUNCHXL.
2. when you need more space for you data (images, sounds, etc.) not for your code (BIN file), you can connect to your CC3200 SD card or secondary serial flash. Access to this serial flash will be on you, it will not be controlled by filesystem sl_ API.

Hi Jan

Thanks for your answer.

Now, I need to optimize my code/BIN file size to fit in cc3200MOD.

Good to know about cc3220SF - is that available in India - how can buy it as an individual to perform experiments?

Appreciate your help Thanks!

Hi Rangarajan G,

I have no information about availability in your country. CC3220SF-LAUNCHXL is available via standard sale channels like Mouser, Farnell, Arrow or TI store. Currently is available CC3220SF-LAUNCHXL and QFN CC3220SF chips. Modules based on CC3220SF are planned to release during few months.

But as I know, CC3220SF is not supported by Energia yet.

Rangarajan -

the CC3220S and -SF LaunchPads are, as Jan pointed out, available through distribution and via the TI eStore. i can see that disty like Digikey and Mouser do in fact have stock.

You can request samples of the -S and -SF modules from this page ==>

Energia developer is at this time is supporting the new CC3x20 devices, but that version has not been released to public yet. last news i had was that it was pushed out to some early adopters / beta testers and after that round will be released. (this was about two weeks ago) - plus some integration work may also be needed to enable actually flashing the onboard flash of the -SF device inside Energia. This may or may not be possible. the developer is/will be looking into this.

sorry about that, try this one: www.ti.com/.../cc3220mod

Thanks! Looks like that is only the cc3220MOD chip, difficult to spend time in board designing - by when can we get the eval board for this cc3220mod in market?

we will have these EVMs in June. They are going through regulatory testing now.
