we use armStoneA9r2 boards with a monitor connected via hdmi. The output of the Linux system (our own Yocto based distribution) works fine via hdmi but we want to display messages in U-Boot as well (when running update scripts that take some time).
We use the F&S version of U-Boot 2020.04 and "U-Boot 2021.04 (Nov 11 2022 - 12:01:25 +0000) for F&S".
After poking around in the configuration of U-Boot without success i checked the source code and found that "HDMI support is not implemented".
How can i continue? Any chance that hdmi output in U-Boot gets implemented?
