A3DPDemo_SNK IAR project + MSP-EXP430F5438 + PAN1323ETU:"Stack Init Failed: -4"

I am trying to run the IAR A3DPDemo_SNK project on the MSP-EXP430F5438 demo board with a PAN1323ETU. I am trying to follow this documentation for the demo:

http://processors.wiki.ti.com/index.php/CC256x_MSP430_Bluetopia_Basic_AssistedA2DPSinkDemo_APP#Demo_Overview

I have the USB port hooked up to my laptop and am reading the output on Hyperterm (9600, n, 8, 1).

I get the following:

"OpenStack().

Stack Init Failed: -4.

Unable to open the stack."

It may be that I don't have some jumpers configured properly or maybe I am missing some hardware-specific defines in the project.

I do have JP3 installed on the MSP-EXP430F5438 which provides for RF power. A red LED is illuminated on the PAN1323ETU.

Thanks in advance for your help.

Hi,

If you select "Debug - MSP430F5438A Exp" In the work-space tab. you should not see this error.

Mind that Assisted A2DP is supported only on CC256xB devices. Please see the datasheet for more details on Assisted A2DP. If I understand correctly you are having MSP-EXP430F5438 + PAN1323ETU, and PAN1323ETU is using CC2564 and not CC2564B.

Can you recommend a radio board besides the PAN1323 that will work with the A3DPDemo_SNK IAR project on the MSP-EXP430F5438 board? Or is there another audio project that works with MSP-EXP430F5438 + PAN1323, perhaps a Code Composer project?

Thank you for your response.

Hi,

You can use any of the CC256xB device

CC256XQFNEM, TI module(CC2564MODN), LSR module( 450-0104B) and Panasonic(PAN1316B/PAN1326B)

CCS can not be used for this(A3DP) demo, The CCS compression is not as good as IAR, so the output binary size exceed the flash size and does not fit in to the audio sink board.

NOTE: the audio is not routed to the microphone jack on the MSP430F5438A in the setup you are using

or you can use BT-MSPAUDSINK-RD (http://www.ti.com/tool/BT-MSPAUDSINK-RD)

Hi Sundeep,

Thank you for the radio board options.

What do you mean "NOTE: the audio is not routed to the microphone jack on the MSP430F5438A in the setup you are using"? Where does the audio go? How do I pick up the audio? I assumed I would be able to hook up an external speaker the way I did with the BT-MSPAUDSINK board.

Thanks so much.

Hi,

The A3DP sink demo does not have support for listening to the audio on the MSP-EXP430F5438 +CC2564B board. As we have it on http://www.ti.com/tool/BT-MSPAUDSINK-RD

There is no Codec hooked up to the PCM/I2S lines of the CC2564B which is where the audio comes from (the audio is not routed through the host processes).

Hi Sundeep,

Thank you for the information about the audio. I should be able to kludge the MSP-EXP430F5438 and BT_MSPAUDSINK boards together during prototyping, and we will be laying out custom hardware soon anyway so should be able to merge the two designs.

Thanks again for your helpful responses.
