How create a image with correct display settings on iMX6ULL - LXDE 2.8b7?

Hello everyone.

I’m using the display ER-TFT070A2-4 with a custom board based on Aster V1.1B and Linux LXDE Image 2.8. This display works fine after configuring the vidargs U-boot variable with parameter below:

setenv vidargs 'video=mxsfb:800x480M-16@60,pixclockpol=1'

My goal is for the display to work right after installation without the need to set the vidargs variable manually. How can I achieve that?

Hi @CharlesDias,

Can you please check if you have a file called u-boot-initial-env in your image file?

There you can configure the u-boot variables and they will be automatically installed with your image. Are you using Yocto to create your image?

Best Regards,

Hi @hfranco.tx,

Doesn’t have this u-boot-initial-env file. I do not using Yocto. I just downloaded this image colibri-imx6ull_lxde-image-tezi_2.8b7.-20200610.tar from Toradex Embedded Linux Long Term Supported(LTS) Releases.

Thanks for your help!
