[U-Boot] rk3288: HDMI out causing boot hang
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.

Try to input "setenv stdout serial" command on the serial console. There might be a chance that stdout/stdin has switched to the video console and the output proceeds there. If the HDMI display shows nothing, it appears like a hang.

It's not an hang. It's the output is not shown. I'm trying to understand the reason

It was a bug of the old uboot
commit 79cdcaced710d955f68066d02327b86be573339c Author: Niklas Schulze me@jns.io Date: Sun Jul 14 10:40:13 2019 +0000
rockchip: video: rk3288_hdmi: Add missing call to dw_hdmi_enable()
The RK3288 HDMI driver's rk3288_hdmi_enable() currently lacks a call to dw_hdmi_enable(). Thus, the HDMI output never gets enabled.

Now I need to test the mainline one

setting serial to stdout, would be a normal case, with this display didn't probe atall.
