Hi I am using DMA with ABIS mode of McBSP of C55x to update the masking patterns in R/XCERA/B. But the thing is that inspite of the fact that i have tied the sync event of DMA to ABIS sync events and enabled the element level syncronisation even then DMA is unable to load the masking patterns in R/XCERB!! so due to that even if McBSP is toggling from R/XCERA--> R/XCERB and DMA being unable to load the pattern there is a loss of bit received during 16 McBSP cycles during the pase of R/XCERB. Even a slight pointer that addresses this problem or if somebody can lead me to some workaround would highly be appreciated.. rgds Saurabh |
