HDMI error on boot

Hello everyone. I need some help. I have a T20 with WCE7. I need to display the desktop win on HDMI output, it does not have to be DualDisplay.
I’ve already followed this tutorial http://developer.toradex.com/knowledge-base/display-driver-registry-settings

The problem is that when I connect the card, if the HDMI cable is connected to it, the T20 card is frozen for a long time on the boot screen, showing the following msg:

“No external RTC found”
“ERROR: I2c Transection Timeout”

After getting into Windows it gets extremely slow.

I’ve read a lot of stuff on the Toradex website, but to no avail.

Does anyone know what happens?

Hello @alvaroy2k,

Did you already try to get the latest 2.0 final image? Probably see the issue 16911 which was fixed in 2.0beta4. Please let us know if upgrading to 2.0 final helps or not.

The latest image you get from here. Also get the latest Update Tool to flash the images to the device.

Hello, Samuel.
Thanks for your response. Both problems have been solved. The solution was to upgrade to version 2.0. My last version was 1.4.
