look here http://www.udoo.org/faq-items/how-do-i-set-up-my-lvds/

 

I followed the link and in terminal I sent this command:

Code:

root@udoo:/# setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1280x1024M@60,if=RGB24,bpp=32 video=mxcfb1:off video=mxcfb2:off fbmem=28M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale mem=1024M

As result I got:

Code:

root@udoo:/#

The I've tried to send the save environment command as proposed:

Code:

root@udoo:/# saveenv

But gived this error:

Code:

/system/bin/sh: saveenv: not found 127|

Rebooting will not help, I got the same screen resolution as before. Would you tell me exactly where I'm wrong?

 

Thank you for your reply...

 

MX6DL UDOO U-Boot > saveenv
Saving Environment to MMC...
Writing to MMC(2)... done

You should execute command "saveenv" on [u-boot consol] like this...
For access to [u-boot consol],
you can see the file "http://udoo.org/download/files/Documents/UDOO_Starting_Manual_beta0.4_11_28_2013.pdf"
page 18... Gook luck..

 

thanks, I'll try !

 

i've tried those commands..

# setenv bootargs console=ttymxc1,115200 init=/init video=mxcfb0:dev=hdmi,1440x900M@60,if=RGB24,bpp=32 ...
# saveenv
# boot

everything was ok..

But after boot, it was displayed only 600x480 resolution...

and then i have do several test... like this..
< Udoo Android Version> <Monitor that we have> <Result>
1. udoo_dual_android_2.0/2.0.1 1400x900 X
2. udoo_dual_android_2.0/2.0.1 1280x1024 X
3. udoo_dual_android_2.0/2.0.1 1920x1080 O
4. udoo_dual_android_1.4.1 1400x900 O

and then i had another test to change the resolution on the android consol with udoo_dual_android_2.0/2.0.1
# wm size 1440x900
# wm density XXX
i could change the size(1440x900), but i can't get the exactly density for my monitor....

Does anybody know about this result? help me.. plz....

 

i have found another issue....
http://www.element14.com/community/thre ... ed-android

By using HDMI <-> DVI convert will not work....
But i don't know why the previous UDOO_Android version did work for my same monitor(1440x900)..
I think there is a little difference in kernel between 4.3 and 4.2....
