Speaking of the real hardware QEMU is emulating... The a9 vexpress has a 'CLCD' display, and it looks like QEMU supports that: https://wiki.linaro.org/PeterMaydell/QemuVersatileExpress For the a15-tc1 vexpress, that has a 'HDLCD' display and that quite probably isn't emulated. Actually, the vexpress hardware consists of a CPU CoreTile (a9, a15-tc1, etc) plugged into a motherboard, and the motherboard also has it's own display of the 'CLCD' type, don't know how much of that setup QEMU emulates. So, it's possible that removing HDLCD from the a15-tc1 device-tree and leaving the CLCD of the motherboard might get that working. -- Tixy
