Hi everybody!
I bought a DLP2000EVM from Ti, and installed with Debian Jessie 8.9 without problems, but when I put version 9.3 i cannot get to work.
Here are some outputs:

I saw in Quick Start guide for DLP2000EVM that the version 8.9 was the only version stable with DLP, this information still true or outdated?
If someone have a clue i really appreciate.
Make sure you have "BOTH" 5V dc jacks plugged in:
Then let's check the output of this script:
sudo /opt/scripts/tools/version.sh
Regards,
I have already both 5c jacks plugged in, the splash screen is ok.

It’s strange because other scripts change the DLP screen (like Splash.py) normally, when i run Mplayer.py i get:
root@beaglebone:/opt/scripts/device/bone/capes/DLPDLCR2000# DISPLAY=:0; export DISPLAY=:0 ; python MplayerTest.py
set slave address: 27
Make sure the display port is set. For example export DISPLAY=:0

^ this old bootloader is getting in the way, so U-Boot Overlays is not
working.. (This cape requires U-Boot Overlays)
i think 2015.10 was the era we used a fat partition in the eMMC.. So
mount it and remove the "MLO" file..
Regards,
Thanks! I didnt find MLO file, but I zeroed the beginning of eMMC with dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=100, and now it boot from sd card!
