Hi. all. I want to do repeated transfer via PCI. I have some questions about DMA interrupt.. 1. DMA generated some interrupt such as FRAME IE, BLOCK IE. What interrupt sources are available? How are those interrupts mapped in interrupt setting? When BLOCK transfer completed, if Setting BLOCK IE(frame =2), ISN_DMA_CHn are available? intr_map(,)?? 2. when repeated transfer via PCI using FIFO, (view->memory using code composer) duplicate data are viewed in memory address. What happened? Any advice on DMA helps me. Thanks. |
