MSP430F5529: BOOST-CC2564MODA stack on MSP430F5529LP

Part Number: MSP430F5529
Other Parts Discussed in Thread: CC2564, CC2564MODA, MSP430F5659, MSP430F5438

Greetings,

I'm building a Bluetooth audio product in which I need the CC2564 to act as an audio sink, spitting out PWM signals to a DAC (also from TI).  I have the MSP430F5529 launchpad right now, the BOOST, and the DAC on a protoboard, and I just want to have some proof of concept as soon as possible.  

I downloaded the CC2564MODA stacks for the MSP430.  How should I go about testing the BOOST module?  The example stack implementations seem all too big to fit on an MSP430F5529.  For example, the SPPLEDemo_lite still needs about 5 more kB to fit the example.  

Right now, any stack will work, as I have a custom PCB built around the F5659 (512kB flash) that will fit any of these examples.  I just want to prove that I can connect to the Bluetooth module with a phone and do SOMETHING on the F5529, so that when the F5659 board and components come in, I can assemble and develop in a heartbeat since I'll have figured out all of the protocols and nuances.   

What do the masters recommend?  I appreciate any advice!

    Hi,

    This stack is the only one that will work withe the CC2564MODA + the MSP430. It looks like the CCS project is configured for the MSP430F5438, not the MSP430F5529. This is why the code is too big for the MSP430F5529. So, for you to run the project on the CC2564 + MSP430 LaunchPad, you will need to port the code to the MSP430F5529 (this will mostly require changing port defines). This can be done by using the devices User's Guide, as well as the porting information found in the documentation folder of the CC2564MODA SDK that you downloaded. You will need to do the for the MSP430F5659 anyway once you receive you PCB.

    Regards,
    Nathan

    When you say "This stack" do you mean the SPPLEDemo_lite? I will try later today but I think the last time I did it, it didn't shrink down much after porting the code. I might be mistaken or I might have done something incorrectly. I'll let you know my progress later today!

    Okay I finished porting the code, and still have flash size issues with the launchpad.  Here is my error and the current state of the problematic parts of SPPLEDemo_lite.map:

    How can I reduce the size of the code of this stack?

    Hi,

    SPPLEDemo_lite is a project built on the wireless stack. Did the project build with no errors after you ported it?

    Please see the following document on some ways to reduce the code size: www.ti.com/lit/an/slaa801/slaa801.pdf

    Nathan
