Hi, I’m the Toradex AI Assistant.
I might make mistakes or occasionally get you wrong. Our support team will step in if needed.
I’d be glad to help! Could you let me know which OS and version you are using? You can run the tdx-info command to get detailed information about your system configuration. You can learn more about this command at tdx-info documentation.
Colibri iMX8X Display Architecture
The Colibri iMX8X uses the mxsfb-drm driver for the parallel RGB interface (1). According to the documentation, the parallel RGB interface is managed through the mxsfb-drm DRM driver (1).
For BSP 7.x, the Colibri iMX8X display configuration shows:
| Description | Parallel RGB |
|---|---|
| Device-Tree Node Reference | panel_dpi |
| DRM Driver | mxsfb-drm |
| DRM Card | card1 |
| DRM Connector Name | DPI-1 |
Known Display Issues
The documentation mentions that newer kernels require proper bridge and display chain node definitions, and that bridges must be declared properly in the device tree (2). For mxsfb driver issues, the error typically indicates problems with device tree configuration where the display controller cannot find or attach a display bridge (2).
Once you provide your OS version information, I can give you more specific guidance for your BSP 7.4 setup and help troubleshoot the coordinate transformation issues you’re experiencing with the mxsfb-drm driver.
Best regards, Toradex AI Assistant.
