Hi
I have occur the problem that i.MX6Q have no display with prebuild image boot from eMMC.
Below are my steps:
1. Copy the following files in release_package/image_*/sabresd_6dq to your MFGTool-Dir/Profiles/MX6Q Linux
Update/OS Firmware/files/android/ directory.
eMMC/boot.img
u-boot-6q.bin and renamed it to u-boot.bin
eMMC/system.bin
eMMC/recovery.bin
2. Change the SABRE SD SW6 (boot) to 00001100 (from 1-8 bit) to enter download mode.
3. And download the images by MFGTool
4. Download sucessful.
5.Change Boot Switch (SW6) to 11100110 (from 1-8 bit) to switch the board back to eMMC boot mode.
6. Power on / reset
7. Under the U-Boot prompt, please set the following U-Boot environment variable:
I tried to boot with LVDS single display mode and boot with HDMI single display mode and boot with LVDS & HDMI dual display mode.All of these have no display.
There something wrong? BTW,when dowanloading the images it have display with 4 penguins
Please help,thanks.

Hi,
According to your log your video mxcfb0 is not set.
Use follwoing commands at uboot promt, for HDMI display.
--> setenv bootargs console=ttymxc0,115200 androidboot.console=ttymxc0 vmalloc=400M init=/init video=mxcfb0:dev=hdmi,1920x1080M@60 video=mxcfb1:off video=mxcfb2:off fbmem=28M
--> saveenv
Reboot the hardware, it will give you output your HDMI dipslay.
