Help! In desperation I ask if anyone knows of some special order that the 65L SPORT's have to be initialized to make DMA work. I am trying to get a DMA driven audio loop running written in C that is something akin to the *.asm example in the SHARC user manual page 9-93. I am setting the control, divisors, setting up the tcb's, enabling the IRQ's, then writing directly to the CPR registers to kick of DMA, but strangley nothiung happens. The divisors must be OK as the chip will loop audio no problem in a simple IRQ only system. Any help at all greatly appreciated. Many Thanks, Max. |
