Ilitek ILI9881C MIPI LCD Panel issue on i.MX93 I am working with a carrier board based on the iMX93, which is connected to a DSI panel. I'm trying to use the ilitek ili9881c driver with specific configurations to get the panel to display correctly, but I have been unsuccessful so far. I do some displays with Weston and modetest. In 2 cas, The panel displays something initially, but then the screen becomes blurry and eventually becomes completely unreadable. Could you please assist me in making it work with the information follow : Panel DSI (https://midasdisplays.com/shop/tft/mdt0500b2ihc-mipi/) with documentation (https://midasdisplays.com/wp-content/uploads/2023/08/MDT0500B2IHC-MIPI.pdf) Driver panel-ilitek-ili9881c for ili9881C IC on linux-imx 6.1.36. Configuration : There are no information about timming configuration on datasheet of Panel then i use the configuration from driver "bananapi,lhr050h41" of "ilitek ili9881c"; Display timings : static const struct drm_display_mode lhr050h41_default_mode = {

Best regards/Saludos, Aldo. Re: Ilitek ILI9881C MIPI LCD Panel issue on i.MX93 Hello Aldo. Thank you for your response. I tested with different clocks, but the issue remains the same: the panel initially displays something, but then the screen becomes blurry and eventually becomes completely unreadable. Strange message in logs: I analyzed the dmesg logs and found an issue with dw-mipi-dsi-imx (see the dmesg log). The fset command doesn't provide the timing information (see the fset command output). New questions : Question 1: How can I resolve this issue? Question 2: Based on the log information below, is there any other issue? 1. Configuration I contacted the panel provider and obtained more information about the timing configuration : Here is my new configuration : linux-imx/drivers/gpu/drm/panel/panel-ilitek-ili9881c.c for 720x1280x60 Hz static const struct drm_display_mode lhr050h41_default_mode = {
