Hello!!! I´m developing a loudspeaker manager with SHARC ADSP-21489. I have some troubles to created delay lines with external memory, using DMA in a sample based project. I can´t started the TCB chained in delay line mode, the project is a variation of the talktrought example including a intermediate buffer to write in the external memory. Attached the project if anyone can help me. Thank you so much!!!!
