Hello.
I am trying to send an image from MCIMX8M-EVK to the original DSI panel with MIPI-DSI, but it does not work.
It worked a few times, but when I restart the EVK after it works, it doesn't work.
Most likely it won't work.
The only change in the state before and after restarting is connecting and disconnecting the connection cable.
(The state expressed as working is the state in which the number of received image frames on the panel side is increasing.)
The waveform of the HS mode data line is attached.
When the left side moves, when the right side does not move.
Is there a possibility that the register setting is bad as the cause of the above not working?
The DSI panel cannot receive data just by restarting the EVK, and the HS mode waveform is distorted. I don't know the reason for this.
Regarding EMI (mixture of noise), I think it is different because there is no noise in the LP mode waveform.
best regards.
Takuya.
