Hello
My setup around Lyra is buildroot with a Waveshare 5 inch MIPI DSI display, dual-boot with A and B partitions. I'm interested in whether I can rotate the display 180 degrees, and whether this happens in U-boot or somewhere at the beginning of the kernel loading. If not, how does the display rotate on that display at all?

The DSI screen's display orientation is fixed, and operations like rotation are typically handled in software. Some drivers only show content in the default native orientation (e.g., the boot logo and VT). Logo rotation can be done via luckfox-config using dynamic device tree overlays. For VT rotation, you would need to check the kernel source for related configuration options or modify the source code directly. After entering rootfs, rotation can be implemented through software, and popular frameworks like LVGL and QT all provide relevant configuration settings.
