Display issues with different edge V pro models

Edge
1

I have purchased four Khadas edge-v pro, and one of the three will drive my usb-c monitor (3840x1930 / 75hz), the other three will not.

They will all drive and power an HD usb-c monitor.

I am running Android 10 using https://dl.khadas.com/products/edge/firmware/Android/Edge_Qt_V210630.7z

Here is Sméagol from non working (snip)

I will try this in the morning!

I have installed Edge_Pie_V19227 update.img via USB-C on Ubuntu with rk-burn-tool, and the display still won’t turn on, but I have different errors.

First, I will supply the hotplug dmesg (this is what happens directly after hotplugging the display),

Android 9 on the Khadas edge-v pro that doesn’t work:

Android 9 bootup dmesg (displays plugged in, non-working Khadas edge-v pro):

@Jordan_Boss I provided your log to the original rockchip factory and got the following reply:
Rk3399 does not support 4K@75hz. Maximum supportable 4K@60hz.

7

So the working model is somehow a fluke? Still unsure why one would work

8

Is there a way to force frame rate? This monitor will display 4k/60, can I choose that resolution/frame rate?

Not sure how to do this.

9

Looks like we are having a similar issue with Ubuntu.

Are you able to connect with UART (minicom)?

10

Yes, I am connected through the TTL UART

11

What are the settings for minicom?

Only getting a few lines of nonsense then it stops displaying however, heartbeat is still going on Edge V.

12

Mine seems to have more issues.

Tried to even get it to burn buster to emmc and it just died in the middle of that. Removed the M2 board and heatsink and it still does it.

Did get back into K by hot plugging the HDMI after getting a heartbeat. Reset to factory and that did not help.

13

I use kermit for my debugging on this board, but minicom should work. Maybe the breaks are messed up.

Baud rate: 1500000

the .kermrc is:
set line /dev/ttyUSB0 // this should be your usb serial adapter
set speed 1500000
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec pack 1000
set send pack 1000

@goenjoy I have changed the monitor to not enable anyhting over 60hz, but I still am unable to see the monitor on 3 devices, and can see the monitor on 1 device.

The DMESG looks like this for the failed system, running Anddroid 9 (latest):

It works fine after setting it with the correct Baud rate, thank you.

Mine is crashing on thermal when trying to fully erase emmc.

That is the second attempt.

Board has passive heatsink on and m2 board installed.

I wonder if they will replace this one?

17

It also gives similar output as before:

[ 48.431004] rockchip-vop ff900000.vop: [drm:vop_plane_atomic_update] ERROR not allow yrgb ver scale

a 4k monitor (3840x2160p60) does not have these issues. Is it an issue with the resolution? as we have hard set the monitor to 60hz

18

I just gave up and ordered another board. Pretty sure mine is just a bad one.

19

Verify with Android 10.0 firmware and provide corresponding log.

20

Here is the log. and still unable.
