Help! Problem with opb_central_dma!

Hi,

    I use opb_central_dma to transfer data from opb_emc to DDR SDRAM(connected by mch_opb_ddr), but it reports bus error. The program runs in the DDR SDRAM, so I think it locks the opb bus. How to solve this problem?

Are you sure that you aren't accessing the memory where your sw application is running out of?  If you overwrite your sw app then you will definitely encounter issues.
