Hello, i've just bought some LVDS 7" for Quad (which is my board), i've followed the istructions for setting them up, but nothing shows up on the screen. So, first of all I've established the connection between my pc and the board with putty (Windows), then I physically connect the LVDS, I insert the micro sd with android flashed inside (everything works if i try with the HDMI so i think it isn't an android problem), I plug the current (original UDOO power supply) and finally I stop the normal boot procedure from putty console. Here what the console says: __________________________________________________ CPU: Freescale i.MX6Q rev1.2 at 792 MHz CPU: Temperature 40 C Reset cause: POR Board: UDOO Quad Watchdog enabled DRAM: 1 GiB MMC: FSL_SDHC: 0 *** Warning - bad CRC, using default environment No panel detected: default to HDMI Display: HDMI (1280x720) In: serial Out: serial Err: serial check_and_clean: reg 0, flag_set 0 Fastboot: Normal flash target is MMC:0 Net: using phy at 6 FEC [PRIME] Normal Boot Hit any key to stop autoboot: 0 => ________________________________ I noticed that in the video tutorial from UDOO the screen has a white light in the moment he plugs the power, mine doesn't do anything. After that I've set the output to the LVDS following the commands provided by Udoo in the LVDS setup page I write saveenv, and then boot. From the putty console I can see that the device can't find the LVDS and if I manually reboot from the button the watchdog restart continuosly the board. I have to flash again the SD to reset the settings and then it starts to work again with the HDMI as it normally does.
Udoobuntu or Android? Which version? Edit: I read Android. What version? Personally I cannot help but perhaps others with Android can give you tips
Android 6.0.1 marshmallow, for Udoo Quad, the one available at this link. It worked with the HDMI computer screen
Hi there @Lorenzo.MdpTech, you have to follow instructions contained here: http://www.udoo.org/docs/Cookbook_Android/UDOO_Android_Settings.html It works with HDMI by default because HDMI is enabled by default, you have to enable LVDS in the Android settings as described in the link I posted above, not by modifying the uboot.
It works, i wasted a lot of time trying to set the output throught serial and the answer was so easy Thanks a lot!
