Tool/software: Linux
Dear Team,
We use custom h/w and software based on DRA746 and SDK 3.02.00.03. I find display goes to blank state after approximately 9 to 10 minutes. I have captured the drm and dss log for this when this happens. See below log.
Is there anyway to avoid this? This doesn't happen when there is continuous update on display via some application.
