I am using the HDMI output connected to a HDMI-VGA converter that is connected to a 15" VGA LCD monitor.
The module had Toradex Linux BSP 2.7 and display was correctly working upon boot(LXDE at 1024x768)
To install WinCE, I booted Into recovery by shorting appropriate points and ran the recovery-windows.bat. from Toradex easy installer to install Win CE 7(latest v1.2) over Ethernet. On the last screen I confirmed the “Image Installed” dialog and rebooted.
Upon reboot, i cannot see anything on screen.
I have used the debug UART to see the following boot messages, they are as follows:
Toradex Bootloader 1.2 for iMX6 Built Jul 19 2017
Splash screen is enabled.
SPL enabled version.
Using 16MB of IPU memory and 80MB of GPU memory.
Board: Apalis iMX6 Quad 1GB
CPU is running at 984MHz.
Using eMMC boot partition (size: 4096 sectors).
Initializing L2 Cache.
Press [SPACE] to enter Bootloader Menu
Initiating image launch in 0 seconds.
System ready!
Preparing for download...
Loading compressed image...
Reading image from sector 40962.
Extracting 43447016 bytes from compressed image of 23848229 bytes
.........................................
Done.
Launching image at 10200000.
It is stuck at that point and I am unable to see an output on the monitor.
From this I can tell that WinCE7 was installed into the NAND and also that the boot-loader is working fine.
I have also changed the resolution to 800x600 and 1024x768 in the boot-loader:

The display still shows nothing.
Please provide some suggestions to get the display working.
Thanks.
