I've got 2 UDOO DualLite machines hooked up to UMSH-8596MD-2T0 displays. Here are the steps I follow: 1. dd udoo_dual_ubuntu1204_v2.0.img to sd card and plug into board 2. plug in LVDS, usb console, and power 3. stop U-Boot and issue following commands: -setenv mmcargs setenv bootargs console=${console},${baudrate} root=${mmcroot} ${hdmi_patch} fbmem=24M video=mxcfb0:dev=ldb,LDB-WVGA,if=RGB666,bpp=32 -saveenv -reset Boots fine and I can log into Ubuntu, but no display on either touchscreen. Am I missing something? Console Output: http://pastebin.com/5x02Rruh (U-Boot 2013.10-rc3-svn109 (Nov 28 2013 - 11:40:20))
That specific env is for our LVDS only. Try to insert your LVDS resolution instead of "LDB-WVGA" es: 800x600M@60
Re: LVDS with imx6dl and UMSH-8596MD-20T My apologies, I miss-typed the name of the panel. It is UMSH-8596MD-20T which we purchase from your site. When I power it up, the backlight flashes very quickly on and then off; barely noticeable. Has the 7" display on your site been tested with the DualLite? Most of the examples that I can find online are using the Quad, though I can't imagine why that would make any difference. Grazie del tuo aiuto. Ciao, Stephano
I started digging into the init function in the board file and it looks like the "MX6DL/Solo only supports single IPU". It's possible that the env settings may need to be changed to reflect this setup. I'll keep digging and let you know what I find. Cheers, Stephano
It turns out that the UDOO board was delivered to my desk (by a coworker) with a 5V power supply. After digging through the code and coming up with nothing, I looked at the power supply on your site and found the issue. This morning I tried with a 12V power supply and everything works fine. Sorry for the false alarm. At least you know that if anyone else runs into an issue where the board works fine but the backlight doesn't fire up on the LVDS display, it could be their power supply. Cheers, Stephano
