Hi,
I have RM69330 OLED driver in 454x454 display. I use CM4 with Bookworm Kernel 6.6 with customized driver (using JDI LT070me05000) to get image in my display. I get first BIST after many day coding. then i buy demo board from manufacturer and sneak MIPI-data and find out that they use only one line MIPI. So i change my driver to 1 line and now i get image but, image is skew with stripes. I try modify all flags, timings and calculate front porch to get integer dividers but, image is always same. But if i change horizontal pixels to +2 or -2 then image is skew opposite direction.
I look MIPI data with osciloscope and use horizontal image to understand better image data and i see that image data move every line one pixel. Image data must be same every line because i use test image where is horizontal color stripes. I try to search help for this problem but no success. Maybe i don't know right words to find answers.
If anybody can tell me what is wrong?
