Hi ,
we are using TLV320DAC3100, for that , no driver is available so we choose tlv320aic3100 as the reference.
we are having Headphone(HPLOUT,HPROUT) and a Speaker(SPK).
Now the card is detected in the ALSA List and we tried with :
CMD: # aplay /usr/share/sound/alsa/Front_Center.wav
[ 227.277403] davinci_mcasp_set_sysclk:
[ 227.298161] davinci_mcasp_hw_params:
[ 227.301965] mcasp_i2s_hw_param:slots:2
[ 227.314739] davinci_mcasp_start:
[ 227.318174] mcasp_start_tx:
[ 227.321133] mcasp_start_tx:tdm_slots:2, op_mode:0,num_serializer:4,txnumevt:32,rxnumevt:32
[ 227.329815] mcasp_start_tx:wait for XDATA to be cleared
[ 227.335302] mcasp_start_tx:enable transmit underrun IRQ
here the the command interface going to hang state -- and NO SOUND. until terminate: these all printk statements only.
in the starter kit - with tlv320aic3106 it is coming once mcasp_stop_tx once the audio is completed we tested with Front_Center.wav sample pcm formated file it is 48KHZ file.
unless we terminate the instance -- mcasp_stop_tx event is not generating -- my doubt is :"is that interrupt is related to mcasp or DMA interrupt is not generating to transmit and the streams is not reaching to end and then command interface- instance is not getting the status and which is leads to hang , until we terminate.
Q 1: MCLK is the CLKOUT1 - to DAC - do we need to configure this in dts -- in the am335x-evmsk.dts file clkout 2 is configured but not clkout is not mentioned any thywhere. -- other clocks i need to check.
Here we are not getting how to debug the next step to make play sound. Please guide me.
Every required parameters are given in the dts file too.
regards,
Viswanath K
