Dear Team,
My customer faced an issue which is FPS was reduced after 1 ~ 2 hours in their aging test when they modify SW to support 2ch 5MP 12fps each stream usecase.
But, there were no issue in their other models - 2ch 2MP model, 1ch 5MP model, and so on.
They found no strange things in input PCLK, VCLK and HCLK as well as power source for DM8127, and their log is as below.
