Hi All,
Did anyone tried HDMI out on rk3288? Enabling HDMI out causing boot hang, during stdout initialization from console.c
Enabled below configs and stdin/out/err environment to probe the DM_VIDEO, seems like the console initialization hangs during stdout initialization.

I saw this some time ago with Armbian with ASUS Tinker Board, but thought I had somehow misconfigured it, and simply disabled it. I can confirm it hangs for me though.
