we're working on a project which interfaces an external codec (EVM TLV
320 AIC 10) to a DSK TMS 320 VC 5416, using DMA channel. we're having problem setting the Control Register (CR) for the AIC 10 codec. as we know, there are 2 ways to set the CR : Direct Configuration Serial Interfacece (DCSI) and Secondary Communication. we're using DCSI with McBSP 1 to set CR 3 (AIC 10 analog loopback). when we send some data, it's not working properly. when we use the secondary communication to read CR, DOUT don't send the CR data. can anybody help us? regards, alvin |

Hello, We have a similar problem, and we are using the AIC10 on a C54CST board, with Code Composer Studio 2.20 and Data Converter Support to generate the files to configure the AIC10 control register through secondary request. We believe we have the correct jumper configuration. We think that maybe we have a synchronism problem between the AIC10 and the 54CST board. Any ideias?
