Hi Tomi, finally we have managed to get the ssd2858 rotator chip + panel running - except one issue.
We see some tearing because the SSD / panel runs at a slightly different VSYNC rate than the OMAP5.
We now have enabled a TE impulse from the ssd2858 chip going to dsiporta_te0 / gpio6_189.
The question is how to enable it on the OMAP5 side.
I presume you are using the SSD2858 with DSI video mode input.
Yes.
There's no TE in that case. TE is only for DSI command mode.
Oops. Hm. How can we then sync the panel (SSD2858 video out) with the OMAP5 DSI sync speed? Sort of “make DISPC wait for external VSYNC impulse”?
