14 years agoI have got the problem ,and it works OK now. there are three problem :
1. I didn't initial the TSE properly ,command_config needed to configure and enable sending and receiving . 2. I used the asynchronous transfer of sgdma, I find the synchronized transfer works OK, but the asynchronous transfer would encounter some error after just less ten transfers. I don't know why . 3.
