Compiling CC2540 code in SDCC

As far as I know, this is not possible. The libraries are built for IAR, and I believe IAR and SDCC use different C runtime models.

You can use a 30 day evaluation version of IAR. If 30 days is not enough, you should check if your university has any IAR licenses or could purchase some. You should check if IAR offer academic discounts as may software companies do.

Is it possible for me to build a library for SDCC or is the code closed source?

The code is closed-source, but that does preclude TI from providing pre-built libraries that are SDCC-compatible? It would be no different to the current situation w.r.t. the IAR compiler (where we are provided with object files), but allow students/hobbyists to join in the fun. :-) 

I would also really appreciate pre-built CC2540 libraries for SDCC. We're a small startup who want to do interesting things with BLE but can't afford the IAR compiler yet.

I agree.   While I'm sure the IAR tools are good, their hefty pricetag precludes hobbyists and students from creating something cool with the CC25xx series / BTE.   It shouldn't take 4 months for someone to compile the source so I am assuming TI has no intention of supporting the student and hobbyist community.   Someone in management should look at the success of Arduino and what it has done for Atmel, then look at how few embedded engineers you can find online evangelizing TI components.  Perhaps you should revisit who is important, old well-funded engineers, or every up and coming kid...  and as an old engineer, I'd like some SDCC compatible libraries too.  Do you guys own a piece of IAR or something?

Since some time has gone since initial question: Is there meanwhile a lib for CC2420 and SDCC?

Or has someone successfully used the delivered IAR lib with SDCC?

I would like to show my support for this notion too.  I'm fortunate enough to be a student at a university with an IAR license, but it bothers me that I won't be able to play with this cool new stuff  when I graduate soon.  Especially for all the iOS developers, like me, who flocked to BLE as the first BT type supported by Apple for a general piconet communication without the need for joining MFI.  The barrier of entry now is certainly lower than the cost of that, but the IAR cost is still keeping out the ones who should be your prized customers - up and coming engineers and developers.  Could someone at TI please inform us of the reason for this?

TI-BLE 1.3 was released some days ago. Is there perhaps a change on this topic?

Is IAR still the only compiler useable to build software for TI's BLE?

Yes, IAR is still the only compiler.

Why? Is there any technical reason? Compiling and generating a lib for a different compiler is perhaps not a big problem?

Or is it just the double work / double testing? Perhaps even double certification / double cost?

Could it be a solution to get a non-IAR lib, which can't be used in a real product, with no support from TI?

General interest:

Does IAR work under Linux? Can BLE software compiled with IAR under Linux?

Suggestion for next TI-BLE deliveries:

Would it be possible to add at least pre-compiled HEX files for each of the delivered examples?

That's a very good idea. Maybe it makes sense to write a wiki page with all those published. I'll see what I can do.

Hi again,

Hex files for almost all BLEv1.3 example projects are found here. I will compose a wiki page with there when I find some time for that.

Also available here:

6332.BLE1v3 Hex.rar

Hey, it is really a great idea to provide procompiled binaries of the examples. Is there a Version for current BLE Stack 1.4?

AS for me, I have a very simple Job for the 2540 to do: just broadcast some data. And I have an external MCU anyway. For such an application I would welcome the idea of AT commands, like Blueradios does: http://e2e.ti.com/support/low_power_rf/f/538/t/123672.aspx#461886

I guess there is no chance to see this in an example one day, is there? So I have to push my activity into the 30 days period.

Hello I'm entering TI + IAR world and always have used gcc compilers in a wide series of chipsets.... 

I was looking if there were alternatives to program and develop for those CC2540 chips, it's a very simple app what I have to do and I don't have the budget to buy another WIN PC (im unix) and... well the history everyone tells.

So, Can I link this binary hex file as static code someway to use say SDCC or xflavor-gcc?
Best regards.

Julian.
