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...

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). Priority of PIO Interrupt is 7, Priority of DMA is 6 (so there should not be a priority problem). ...

Hallo, would anyone give me an example of an ISR serving a DMA interrupt on completion of a transfer? I need an example where the ISR reconfigures a new transfer with the same characteristics of the previous transfer. Thank you Valentina Labels: General ...
