    Screen Resolution with preinstalled Android

    kas671

      I connected riotboard via HDMI to different monitors with different physical resolutions and android started every time with an resolution of 640x480. How can I change this? Thanks for help.

          You should be able to change the resolution in u-boot mode passing the following arguments:

           

            MX6Solo RIOT U-Boot > setenv bootargs console=ttymxc1,115200 init=/init nosmp video=mxcfb0:dev=hdmi,1280x720M@60,bpp=32

          video=mxcfb1:off fbmem=10M vmalloc=400M androidboot.console=ttymxc1 androidboot.hardware=freescale

           

          MX6Solo RIOT U-Boot > saveenv

              Great, now I'm worse off than before!  What were the settings before I tried the above? With the above settings neither of the  three small (less than 40") HD TVs I have at my disposal will resolve the settings and my HDMI equipped HP computer monitor isn't happy with them either. My monitor suggests 1920x1280 at 60Hz.  I don't think the Riot board will go that high.   I tried editing the settings "shotgun" style to see what works with my gear. The best I could come up with is a 24 Hz setting, but it was real laggy. Could you give me the line that will restore it to what I had?  Or even better give me more possible HD resolution settings to try. What settings are used in the video for the 2 part Android Programming tutorial?

                  Here's the original settings:

                   

                  Which appear to be the same as written above, so not sure why that would make things worse.

                      What's the command line that generated the above output?  I'll try mine and see if these are my settings.  Prior to me loading the "correct" settings, my Riot Board was booting into the 640x480 mode the same as kas671 was talking about.  I loaded the settings that vandana suggested and none of my monitors would resolve it. I think I eventually got a resolution that would show by by changing @60 to either 24 or 30 ( I can't remember which).  It still didn't display a full HD desktop, and the screen flashes.

                          Connect to the terminal via J18, hit a key to stop the boot process, and at the U-boot prompt type "print". It's about in the middle of all the stuff that will scroll past.

                              My print out is identical. Is there a chance we were sent different Android revs?  My info is:

                              I also notices in the videos, their lock screen wallpaper (besides being 1280x720 res) is a different image.

                                  Here is my DeBug cosole output on boot.  Can anyone look at this and see why I can't get hdmi resolution?

                                    My Lock Screen Wallpaper was also different. I get full 1080 though on Samsung monitor out of the box. Does anyone know how to use the HDMI and tell it to use the Audio Jack out for sound?

                                        After playing around with this some more, I haven't yet found a solution but I did find that it has something to do with the particular monitor it's being hooked up to.

                                         

                                        Using a HDMI->DVI connector affects the resolution, as it comes up at 640x480 when using that cable. But the same monitor when connected via a HDMI cable will show up at the correct (1280x720) resolution. In Linux I tried playing around with xrandr arguments to get the resolution up when connected over HDMI->DVI, but to no success so far (it complains about "screen cannot be larger than 640x480"). Googling i.mx6 and hdmi/dvi, this seems to be a common issue, and seems to be related to not getting the proper EDID info from the monitor when connected over the adapter.

                                         

                                        Meanwhile on my TV at home via HDMI, Android would not display on it, with the TV complaining about incompatible signals. However the same board would work when I booted Linux on it, and show up at the correct resolution (1280x720). I could also adjust the Linux resolution by changing the U-Boot arguments, but was not able to find a working Android solution. Meanwhile other TV's and monitors I connected with this same board worked correctly on both Android and Linux so it seemed to be a rare case.

                                         

                                        Out of the box I have the same green background as in the videos, but when connected via the HDMI->DVI cable it's in phone mode so it doesn't look quite the same since at full resolution it'll be in tablet mode.

                                         

                                        Mark: I noticed in the Linux sound settings there's a page to configure what the default sound output is which I would assume works. For Android, it seems the solution is to get a special cable or box that extracts the audio from the HDMI signal, but there's not a way to do it as far as I could Google inside Android itself.
