Hello, I am writing this mail to suggest one thing regarding FIMC H/W setting. You wrote the below code for setting S5P_MSCTRL_FRAME_COUNT as one. cfg |= (S5P_MSCTRL_FRAME_COUNT(1) | S5P_MSCTRL_INPUT_MEMORY); I think itâs better way to set the value of S5P_MSCTRL_FRAME_COUNT as 4. Because, this value means input DMA burst count. The default value of input DMA burst count in FIMC is 4. And I guess if the value of less than 4 is set as input DMA burst count, the performance of input DMA in FIMC will be lower. I want to know how about your opinions. Thanks.
