Hi Team,
My project used sn65dsi83 to achieve dsi to LVDS function. Currently, we found black screen issue occasionally when we did the test.
After initial analysis, we verified below items.
- Set Reg 0x3C , value: 0x10，Panel can show TestPattern
- Use I2Cget，we verify below table parameter is writing into chip in addition to red part. But we dont think these are root cause because we got the same results in another normal case.
- There is signal on CPU DSI.
I want to know if sn65dsi83 reg can indicate the dsi status is ok or not ok. Or any other information can verify the why chip didn't show the correct signal?
