Hello,
I'm developing an automotive audio system using PocketBeagle 2 + AD2428W.
Current configuration
- PocketBeagle 2 outputs audio through McASP
- McASP is configured as 4-channel output
- AD2428 receives:
- DRX0 = TDM2 (2 channels)
- DRX1 = TDM2 (2 channels)
- This configuration works correctly.
Desired configuration
I would like add one more AD2428 to transmit audio to another AD2428 located elsewhere.
But, I have to keep my existing A2B network because hardware limitation.
(The easiest way is adding one pair McAsp and AD2428)
So, is there any way for an AD2428 to transmit using A-port as upstream?
Host (McASP)
│
AD2428 Main
├── B-port → Existing A2B speaker network (already working)
│
── A-port (Upstream)
│
AD2428 Subordinate
│
ADAU1452
│
ADAU1761 DAC
│
Additional speakers
In SigmaStudio, I can enable Upstream, but I cannot find any A-port where the upstream audio channels are assigned or routed.
Thank you for always helping me.
Best Regards,
LocoField
