Part Number: DRA722
We are use dra722 chip to capture 4 AHD video, using custom board, the decoder is rn6864m (4 AHD to mipi csi2 , 4 lanes), software is based ti-processor-sdk-linux-automotive-dra7xx-evm-6.00.00.03 . We can capture any virtual channel video stream, But some problem in capture 4 channel video stream simultaneously.
1. I don't understand the concept : Context configuration , how to configure? and what is The CPort ? user defined? range is 0 to 31?
2. I try to config CAL_CSI2_CTX0_0 , CPort is 0 ,VC=0 , and CAL_CSI2_CTX1_0 , CPort is 1 , VC=0, then config CAL_WR_DMA_CTRL_0 , CPort is 0, and CAL_WR_DMA_CTRL_1 , CPort is 1 , enable IRQ_WDMA_START0,IRQ_WDMA_START1,IRQ_WDMA_END0,IRQ_WDMA_END1, but only IRQ_WDMA_START0 and IRQ_WDMA_END0 interrupted.
3. CAL_PIX_PROC_i (i range is 0 to 3) , not 0 to 8? Not each context corresponding one? why?
