Hi ti team,
Problem :55 degree aging flash screen in small batch production
Video scheme: AC8257→MiPi→DSi83→10 line LⅤDS→ds90UB927→2 line ---- display screen 924 line 10 line LVDS screen.
Exception Description:
1: production line aging 20,7 flash screens, preliminary determination of the problem with the host.
2: the problem was fixed: after the SN65DSI83ZQER interrupt output was lowered, SOC reset the DSi83, which caused the flash screen
3: When the AC8257 detects a DSi83 anomaly, the action is shielded, the log and phenomenon are observed, and when the exception is abnormal, the screen does not flash
4: Through the sn65dsi83 datasheet, understand that due to sn65dsi83 abnormal will pull this interrupt foot to low. At the moment, we can't locate why the sn65dsi83 is abnormal, and we ca n' t find the cause of the anomaly
Could you pls help us check below:
Except the below three Note in the specification, is there any other possibility that this may be the result (Causes the sn65dsi83 irq pin to low) ?
