Danielemazza Posted January 17, 2020 Posted January 17, 2020 I'm trying to disable the HDMI output on my A20-OlinuXino LIME. I have tried to disable the HDMI from the u-boot console using this commands : -setenv video-mode sunxi:1024x768-24@60,monitor=none -saveenv I have also tried to recompile the boot.cmd but even in this way nothing. Corrently i'm using : Linux lime 4.19.62-sunxi #5.92 Where is my mistake? Thanks in advance.

Last time I had to apply this patch:https://github.com/armbian/build/blob/master/patch/u-boot/u-boot-sunxi/remove-boot-messages-from-hdmi.patch.disabled ... but its also outdated due to code changes. But it gives you an idea what to look for.

If you don't understand hints, study study study or hire someone that have time and ability to use them. I don't have the time to study the problem once again - it has been years since - and guide you there. It is way too expensive for something that only generates costs.
Danielemazza Posted February 25, 2020 Author Posted February 25, 2020 Hi to all: I do not if is the right way but it 's works and in my opinion the knowledge must be sharing(that is the only way for keep alive the open source ). So following these instructions i recompile the u-boot and the kernel obviously i have had remove the graphic drivers. U-boot: https://linux-sunxi.org/U-Boot Kernel: https://linux-sunxi.org/Mainline_Kernel_Howto This is not my work and it been done in my spare time indeed may not be the right way Best Reguards

A patch for easy change has been updated two weeks ago. If you want to remove boot messages from u-boot, you only enable it (remove .disabled) patch/u-boot/u-boot-sunxi/remove-boot-messages-from-hdmi.patch.disabledhttps://github.com/armbian/build/commit/b41834796294709644a4e503086bfbdd27b87785#diff-cab794eb45546ba1b58d2948585a2cb2
