Disabling DISPLAY_ROCKCHIP_HDMI (and those other than EDP) didn't change anything with 2400x1600. (What I was saying is if someone in the future enables it on PBP, the eDP would likely break; but maybe that already happens with the existing code in non-rk3399 devices. A minor issue, though.) > I see that you've added the needed rockchip,panel properties, so it's > possible it's related to the driver but I'm surprised that the > blacklight turns off. iirc, the driver is only turning it on. FWIW, commenting out panel_enable_backlight() in rk_edp.c or adding a panel_set_backlight() after that call didn't get the backlight to stop turning off or get it turned on before my loop in board_late_init().

It doesn't have ethernet, I don't think USB works either -- assuming you mean I'd use a USB-to-Ethernet adapter. > btw, I'm not sure what's the current practice in uboot m-l, but maybe we > can go on debugging your issue off-list ? Sure. At least, I guess most of it would be spam-ish to the people already in Cc.
