No, we are using the development board for ESP32,
I modified the drivers you suggested, but a timeout occurs during their initialization:Full log:Modified driver:Modified overlay:
Based on my earlier drivers, I checked the signal on the D0 line with an oscilloscope as sent by the ESP32, and I noticed it includes an extra command that's not present in the data from the RPi. It’s probably a start-of-line marker. What do you think? Is there a way to enable something like that on the RPi?
Signal measured on the D0 from RPi:Signal measured on the D0 from ESP32:
Zoomed ESP32 command, It looks like the command is being sent after the vertical front porch and before the vertical back porch.
I modified the drivers you suggested, but a timeout occurs during their initialization:
