rock-3a-radxa-5inch-touchscreen.dtbo.tar.gz

Update: using this overlay on Debian OS (Raxda Official) the display works great and also the touch is acceptable. I've tried to copy and past this specific file attached on the "rockchip" folder and edit the "dietpiEnv" file adding this file in position "overlay=rock-3a-radxa-5inch-touchscreen.dtbo". Boot the Rock 3A but nothing change. I hope that someone can help me to implement this overlay here.

Thanks

This overlay is made for the legacy Linux 5.15 kernel provided by Radxa, not the mainline Linux 6.1 (or 6.6).

Setting HDMI display resolution for console mode is another question: #5641 Found some more possibilities here, but needs testing: https://github.com/MichaIng/DietPi/issues/6550#issuecomment-1677967216
