UniformBuffer Posted March 24, 2020 Share Posted March 24, 2020 Hi, i have some difficulties to add some boot parameters to the kernel. From what i read, the most safe procedure is to use the armbian-config tool, that will add the parameters to /boot/armbianEnv.txt file. As i have understood, the armbianEnv will be readed by the boot.cmd/boot.scr at launch, without need to recompile anything. I have added the needed parameters using armbian-config, but does not work. To be precise, the commands that i have to add are: Spoiler video=composite-1:d video=Composite-1:d I need to disable the drm composite output because my monitor is.....well, not good and the composite output cause a lot of problems. I have also tried to enable the boot logo changing the value from "disabled" to "enabled", but nothing has changed. I'm doing something wrong? I miss something? I have also tried using the procedure described here without success: https://docs.armbian.com/User-Guide_Fine-Tuning/ Can someone help me? Thanks for the attention and the dedicated time. Have a good day Link to comment Share on other sites More sharing options...
chwe Posted March 24, 2020 Share Posted March 24, 2020 I would try "video=composite-1:d".. this goes in over u-boot variables, and they tend to mess up stuff.. cause it's then more like extraargs=video=composite-1:d whereas it should be extraargs="video=composite-1:d".. 1 Link to comment Share on other sites More sharing options...

So you suggest to change the command to "command" right? I tried it but nothing happen. Maybe your suggestion works, but the command itself doesn't. As i know, all current kernel boot parameter can be found on /proc/cmdline file, but there isn't. Solution found: I tried to use some of the texts you suggest, specifically the extraargs=video=composite-1:d (without quotes) works. Seems that the script look for the extraargs= prefix and add everything next to kernel parameters. It appear on /proc/cmdline and the command seems to work, now that connector is listed ad "disconnected". Thanks a lot for the help and the dedicated time! 1 Link to comment Share on other sites More sharing options...
