Hi,
We have a custom board with an AM3517 processor and a TLV320DAC32 Audio DAC. We are running Linux as the OS, using the source from the AM35x-OMAP35x-PSP-04.02.00.07 support package. I haven't found a Linux driver for the TLV320DAC32, but the Linux source includes the codec driver tlv320aic3x. The tlv320aic3x is a driver for both the aic32 and aic33 for which the TLV320ADC32 is software-compatible.
So we are trying to use the tlv320aic3x driver with the TLV320ADC32, is this possible?
At the moment I have set it up and when running the ALSA speaker-test program as below. I believe the TLV320ADC32 is configured to master mode and when measuring the pins I have 26MHz on MCLK, 48KHz on WCLK and 1.5MHz on BLCK and I have data on the DIN pin. But I have no signal to the speaker. Do I need to do some modifications of the tlv320aic3x driver to make is work with the TLV320ADC32?
# speaker-test -c2
speaker-test
1.0.23
Playback device is default
Stream parameters are 48000Hz, S16_LE, 2 channels
Using 16 octaves of pink noise
Rate set to 48000Hz (requested 48000Hz)
Buffer size range from 640 to 32768
Period size range from 8 to 16384
Using max buffer size 32768
Periods = 4
was set period_size = 8192
was set buffer_size = 32768
