AM3359: McASP connections to TLV320AIC23 codec

Part Number: AM3359
Other Parts Discussed in Thread: TLV320AIC3104

Team,

Can you please assist with the question below from my customer?:

I am really struggling with an issue of connectivity between the AM3359 and a TLV320AIC23B CODEC using the pinmux tool. I’ve read about the MCASP extensively but am struggling to understand how to map the CODEC properly to the MCASP using the tool. This is a problem that was found late in the review process.

Please see the attached excel document:

1. I tried to draw on existing work – I used the Beaglebone Black Master design along with the Audio Cape
     a. The BB Black uses the AM3358BZCZ100
     b. The Audio Cape uses the TLV320AIC3104 CODEC
2. Using existing schematics available online I mapped the connectivity between the above devices
     a. See excel document column A-G
3. I tried to map the pins to what I THINK they are in the McASP.
     a. See excel document column H
4. I am using the following parts:
     a. AM3359ZCZ
     b. TLV320AIC23BPW CODEC
5. I then tried to map McASP to the new CODEC
     a. See excel document column I-J

I need confirmation that I’ve wired my two parts successfully. There is not a lot of documentation really explaining the McASP in a way that map to the CODEC (at least to me).

Thanks,
