Dear,
I have bought an LCDKC6748 board recently but I can't use AIC3061 codec. Unfortunately the similarity of LCDK and OMAPL138 has made a lot of problem and i could not find the right driver or some c code specified for LCDK so I had to follow the instruction in c6000 workshop: http://processors.wiki.ti.com/index.php/C6000_Embedded_Design_Workshop#C6000_Embedded_Design_Workshop_Videos_-_NOW_AVAILABLE.
Lab11 of 2013 was the project which setup codec with Hwi for Omapl138 but this code does not work for LCDKC6748. I checked the MCASP initialization and noticed that AXR selection is different in LCDK so I configured them to AXR13 for transmitting and AXR14 for receiving by changing DIR and SRCTL registers !! in receiveing path MCASP buffers are filling and also they are updating properly but in transmition path to codec there is noting! XBUFF and RBUFF are both filling with data and ISR routine is calling properly. I also checked the receiving and transmitting path by Oscilloscope and we have some pulses in receive path but still there isn't any pulse in transmitting path.
I would be grateful if you answer me.
