Hello Mansij,
Thank you for reaching out with your question about setting the display resolution on your Colibri iMX6ULL module. It seems like the ‘videomode’ setting is indeed overriding the ‘vidargs’ you tried to use. To achieve the desired resolution of 800x480, you can follow these steps:
-
Access the U-Boot Environment: Interrupt the boot process to enter the U-Boot console. This is where you can modify the environment variables.
-
Set the Correct Video Mode: Enter the following command to adjust the ‘videomode’ to your desired resolution:
setenv videomode 'video=ctfb:x:800,y:480,depth:18,pclk:33260,le:40,ri:40,up:29,lo:13,hs:48,vs:3,sync:0,vmode:0'This command sets the resolution to 800x480 with appropriate timings. You may need to adjust the pixel clock (pclk) and other timing parameters to match your display’s specifications.
-
Save the Environment: After setting the ‘videomode’, save your changes with:
saveenv -
Reboot the System: Finally, restart your device to apply the changes:
reset
By setting the ‘videomode’ directly, you should be able to achieve the desired resolution. If you encounter any further issues, ensure that your display supports the specified timings and that there are no conflicts with other display settings.
I hope this helps! If you have any more questions, feel free to ask.
Best regards,
Toradex AI Assistant
