Round Display - boot.ini - need help to configurate

Post by Vahag » Wed Mar 04, 2020 7:09 pm

Hello board members,

first of all I want to say (((THANK YOU))) to voodik
but also thanks to all the other active members here for helping out with thair knowledge
I am following this board now since 2 months and buyed a odroid xu4 for my project.
I chosed this board because of the most android friendly community.

BUT NOW to my problem that I cant solve since two weeks:

I buyed a few round lcd screens from china for my project. the Problem is, the displays doesn't work as I want.
for example, I want to rotate the display 90 dagree to the left, because the conector has to be on the right side of the screen.
next thing is, it flickers and has some kind of black overlays on the outer sides and has problems with the frequency and so on.

I have a config file (txt) from the developer, which was working fine with the raspberry and with few other boards.
But in this board it doesnt do anything. When I copy the necessary parts to the boot.ini with the app Solid Explorer and save, nothing happens after reboot.
Also, as soon as I use the odroid utility app for something, it overrides my file.

Don't know how to fix this. I'm a noob in programming and stuff, please guys, can someone help me out?
I am ready to pay for the help with paypal, because I know its work and I know you guys have also a life. :D

So here is my Setup:

Odroid XU4 running with this Android build and an EMMC, powered by a DC12v to 5.2v converter. I connected the small Odroid wifi and BT dongles and a joystick.
The display I am using is a 800x800 pixel round screen from a chinese company. Its connected to a HDMI converter.

parts from the txt file I have to integrate into my boot.ini on SDcard partition from EMMC:

force_trubo=1
gpu_freq=300
core_freq=400


# HDMI Basic configuration
hdmi_pixel_freq_limit=400000000
hdmi_timings=800 0 40 12 40 800 0 12 12 12 0 0 0 60 0 44740000 0
hdmi_drive=2
disable_overscan=1
max_framebuffer_width=2560
max_framebuffer_height=2560

# Landscape-1 (Flexible cable is right side.)
#display_rotate=1
#framebuffer_width=1920
#framebuffer_height=1200


This text was for the raspberry pi 3b config file, or so.
I know It cant work with this boot.ini but I hope I can implement as much as possible with your help.

Thanks for reading this roman and sorry for my bad english :D :roll:

This boot arguments for raspberry pi only and cannot be used with any Odroid.
Boot arguments depending own kernel and drivers.
You can rotate 270 degree.

It worked with rockpi64 with android. I also have android drivers for the display. But thats another story because I cant implement them (absolute no knowledge in building a kernel or rom...)

Maybe there is someone here who could do it for me, with a fair payment. ๐Ÿ˜›
