Maybe someone can help here. I have installed the Firefly last ubuntu build (Firefly-RK3399-ubuntu16.04-20180416112819.tgz found in the firefly website) and it "almost" work for the Yundoo Y8.
After flashing this image, the Y8 shows the blue light and after a few seconds, the ethernet becomes active (I can see the ethernet lights flashing, so the driver seems to be initialized)
But HDMI is down, I can not see the console. At UART serial console, I see this: https://pastebin.com/K8b8yEE0
From this log, it seems to work everything except the HDMI.
This is the output related to HDMI initialization:
[ 1.413003] i2c i2c-9: of_i2c: modalias failure on /hdmi@ff940000/ports [ 1.413605] dwhdmi-rockchip ff940000.hdmi: registered DesignWare HDMI I2C bus driver [ 1.414348] dwhdmi-rockchip ff940000.hdmi: Detected HDMI TX controller v2.11a with HDCP (DWC HDMI 2.0 TX PHY) [ 1.415807] rockchip-drm display-subsystem: bound ff940000.hdmi (ops 0xffffff8008cec920) [ 1.765870] dwhdmi-rockchip ff940000.hdmi: PHY PLL failed to lock [ 2.147015] rockchip-pinctrl pinctrl: pin gpio4-17 already requested by ff940000.hdmi; cannot claim for ff130000.i2c
After the flashing I get no blue light anymore nor any UART log. So I reflash the Firefly resource image (previously backuped) and boot again the device. It goes to blue light and no HDMI as before, as expected. Looks like the rk-kernel.dtb from Y8 (android 7.1) is not good for ubuntu 16.04.
I was thinking as next step to connect via ssh and solve the HDMI problem there if possible.
Does anybody know how to fix the HDMI issue?
