Latest ALIP images are not available for Hikey boards. This is due to the fact that both Hikey and Hikey960 boards are sharing the same rootfs image and there is no upstream HDMI support for the later one (HiKey960). So, I have just enabled HDMI bits for Hikey board in kernel config and rolled out developer image so that both boards can run somoothly.
I will add ALIP image once HDMI support lands in mainline kernel for Hikey960. Sorry for the inconvenience.
