Hi.Every body. A simple question: how to write data from Mcbsp to memory space. Should I use EDMA? And if so ,how to configure the parameter of EDMA?If the data is 8-bit or 16-bit,would any error occur? I ask the question because I encounter a problem:when I use c6711 DSK to tranfer data from McBsp to EMIF memory space through EDMA, if the data width is 8 or 16, then only the data at word address(that is the lowest two bits are 00) can be written correctly, and data at other address are written 0. Who can explain the problem? Thank you. |
