Manuel, It sounds like your LCD7 Cape may have issue with the signal integrity when booting with BBB: http://elinux.org/CircuitCo:BeagleBone_LCD7#Known_Issues
Have you tried booting up your LCD7 + BBB setup from a bootable SD card? The process of creating this type of SD is similar; however, instead of flashing the eMMC on BBB, it will allow you to boot directly from the BBB's micro SD card slot: http://elinux.org/Beagleboard:Updating_The_Software#Image_For_Booting_From_microSD ~Hieu On Sat, Feb 1, 2014 at 12:28 PM, DoctorP <[email protected]> wrote: > Hi, > i'm the newest newbie of all, and I'm having a problem that I can't fix.
