TMS320C5535: AIC3204 demo

Nancy Wang

Part Number: TMS320C5535

Hi team,

I tested demo aic3204 located in ezdsp5535_BSL_RevC\ezdsp5535_v1\tests, but i could only heard voice from left channel of the earphone. I tested on tms320c5535 ezdsp. I have measured the signal from HEADPHONE_LOUT and HEADPHONE_ROUT and i found there was no signal output from HEADPHONE_ROUT as long as i inserted earphone. But they were normal without earphone. Please help to verify.

Nancy,
Are you running a MONO demo? if so, you will only hear audio from 1 channel.
Also, are you using the C55x CSL? software-dl.ti.com/.../index_FDS.html

I would suggest using the examples in the CSL rather than what's on Spectrum Digital's site to evaluate the EVM.

Hi Lalindra,
I have tested the demo audio_playback_test in CSL. And i configured chtype to both I2S_CHAN_MONO and I2S_CHAN_STEREO. But still only one channel worked. Please help to verify.

Nancy,

I'm confused, are you trying to run a C5545 demo on C5535?
