I'm debugging an SBC with i.MX6SoloX MCU on it. There is video output using LVDS lines and NVME drive on PCIe.
When I copy significant files over PCIe into NVME LVDS output flickers (the video page is static at this time).
What should I look for? Could it be an issue with Linux BSP or this is more of a signal interference issue in hardware?
Does video output depends on the load of the CPU core or DMA?
