Pine64 + waveshare display?

[hamzahbondok]

Hi! Did you read http://forum.pine64.org/showthread.php?tid=980 for switching resolutions? You have to make sure that the HDMI output matches something your display can support, I am not sure if your display's resolution is a supported mode atm... check here https://github.com/longsleep/sunxi-disp-...tput-names

Thanks for your respond. But despite of your references the solution did not work for me, as so far. none of the both options won't display more than a black striped noise:

Code:

cat <<EOF| sudo tee -a /boot/uEnv.txt
optargs=disp.screen0_output_mode=480p //or i
EOF

Code:

sunxi-disp-tool switch -mode 0
sunxi-disp-tool switch -mode 2

But the strange thing is that the pi just works straight ahead..

If I take a view to the config, which are available on the rpi2, the /boot/config.txt would give me the opportunity to set some config according to my hdmi output for my display..

Code:

#hdmi_force_hotplug=1 //disabled
hdmi_group=2
hdmi_mode=87
hdmi_cvt 800 480 60 6 0 0 0

resolution 800 x 480,
refresh 60Hz,
aspect ratio 15:9,
no margins,
no interlace,
normal blanking

It doesn't even matter to me if the touch function is working or not.. But only a output to the display is enough     

i have the same problem. can someone help steer me the right way
