Hi,all I have been annoyed by mcbsp of c6203 from the beginning of our design and test. I have now find out some of the problem. 1. the address of XCR0 is wrong in csl_mcbsphal.h line 851: #define _MCBSP_XCR0_ADDR 0x018 4?(c) 0010u 2. the macro "MCBSP_IO_ENABLE" and "MCBSP_IO_DISABLE" in mcbsp.h are just with the opposite feature 3. if use function "DMA_configArgs" in CSL the dma can only start once(I have not find out the problem). Now I use HAL of DMA to start a channel of dma Wang Tao R&D Engineer ShangHai ORDA Opto-Electronic Science & Technology Co., Ltd 01/14/2003 -- |

Tao Wang- Thanks very much for posting that. Many people might be helped. I understand what you have gone through. A year ago we wrote our own .h / macro files, because of some unexplained DMA problems. The problems went away, but we never knew specifically where is the issue in the Texas Inst. C6xxx .h files.

The 1st and the 3rd are with CCS2.0 and plus for c6000's CSL. I begin
with CCS2.0.0 and now I use ccs2.12.14. The 2nd is with Peripheral Support Library.
