Trouble using DLPDLCR2000EVM in BBBlack with Debian Jessie 9.3

[Daniel Grabert]

 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Start guide for DLP2000EVM that the version 8.9 was the only version stable with DLP, this information still true or outdated?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

 I have already both 5c jacks plugged in, the splash screen is ok.

END

   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..

[Daniel Grabert]

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!
