this time even without specific hack, just a config : CONFIG_PHY_ROCKCHIP_INNO_HDMI=y CONFIG_VIDEO=y CONFIG_DISPLAY=y CONFIG_VIDEO_ROCKCHIP=y CONFIG_DISPLAY_ROCKCHIP_HDMI=y U-boot 2024.07( I think also 2024.04) then enables the inno hdmi_phy driver 2024.10-rc5 even shows the u-boot logo, t...hey seem to still maintain the RK3328 hdmi.... -…I will look into that GOP- thing….
