1.2 DMA DMA设备, 在系统中分为MASTER与SLAVE, 另外一个非常重要的能力就是是否支持Scatter/Gather. 这些能力终于表如今DEVICE_DESCRIPTION所定义的数据结构的成员中, 比如:DmaWidth, ScatterGather, Master, Dma32BitAddresses, Dma64BitAddresses. 系统终于将各种不同类型的设备DMA抽象为DMA_ADAPTER的实例, 它是设备...
分析vpfe_capture.c发现vpfe_imp_dma_isr未被调用,分析videobuf-core.c发现vb->state总是处于VIDEOBUF_ACTIVE,导致videobuf_waiton未调用,所以vpfe_imp_dma_isr。output from resizer(data flow path 2)未成功。这时,我设置了ov9726的0x4700为0xa(CCIR656 mode enable,CCIR656 v select),再次运行demo,vpfe...

I have a DMA controller which I want to use on an IRQ coming from a PIO. The DMA works fine and also the IRQ does. But when I try to call the DMA transfer function INSIDE the ISR from the PIO, the DMA doesn't send it's Interrupt at the end (when transfer is finished). ...
