Waveshare 5.5 AMOLED and N2 with UBUNTU

Unread post by ManuelFantoni » Fri Jul 05, 2019 1:40 am

Hi, my display/touch Waveshare 5.5 doesn't work well plug & play with Ubuntu (for N2) but it works plug & play with Android (for N2).
I've read https://forum.odroid.com/viewtopic.php ... .5#p261109 but I'don't know if this is applyable to N2, help me pease :D

What should I do? how should I edit the file boot.ini ? 1080x1920_waveshare_125590.bin ?

AFAIK, it's not been tested fully yet and in progress, maybe the stock just arrived today for testing.
Let us update sometime soon in the thread.

pls have a read here ....if it may also help admin....phase

https://www.waveshare.com/w/upload/b/be ... ual_EN.pdf

Code: Select all

force hotplug dection....
the oled also has option for extra power input via a usb otg..i suggest you also try an otg-usb cable for extra power...


possible 1080 modes to force to choose from..try .setenv one mode at a time set autodect to false...

# "1080p60hz" | 1920x1080 Progressive 60Hz
# "1080p50hz" | 1920x1080 Progressive 50Hz
# "1080p30hz" | 1920x1080 Progressive 30Hz
# "1080p24hz" | 1920x1080 Progressive 24Hz
# "1080i60hz" | 1920x1080 Interlaced 60Hz
# "1080i50hz" | 1920x1080 Interlaced 50Hz


i think that odroids should if at all possible support these waveshare screens...
they have quite an extensive range..
although i am wondering about the particulars may well be an native resolution of 720p .... or differ from model to model....the hdmi versions i am quoting about here... here...

still i wonder if the problem may well be just that the user needs the extra support of the otg input power as well..

Hi,
To run the waveshare 5.5 moonitor on N2, I need to check some about hdmi pixel clock and colorspace option.
I've confirmed this monitor works on ODROID-C2 with display auto detection option,
but with N2, not yet.

Please let me check them for a couple of days,
and I will share the status here once I find a solution. ;)

Hi @ManuelFantoni, @phaseshifter,
Let me share current status with N2.

I've tried display auto detection on N2 with this monitor and I got 1080x1920 portrait display but it's very flickering and cracked-looking.
And I made a manual display mode patch based on the monitor's timing and pixel clock but it didn't work well.
So I'm still looking into this issue and adjusting N2 hdmi driver based on 135.27MHz pixel clock and its native timings.
So far it's complicated for me to find where the actual cause is.

Please give me several days more.
