RE: LCD Cape for the BBB/BBG

Hello,

I am using a BBG to display an OS on my Debian Distro. I received help once or twice before on another service but I thought I would come here to see if anyone knew of my issue.

Here is the cape:

Here is my version.sh file. Sorry for the long winded approach.

P.S. If anyone can figure out what is incorrect, please let me know. I am on 4.19.94-ti-r35 and Debian Image 2018-10-07.

Hello Again,

Please forget what I was saying.

Seth

P.S. If that version.sh script helps anyone, good. Outside of that idea, hack!

@silver2row, little confused, does it work?

If it doesn’t, do you have usb power plugged into both the beaglebone green and the seeed lcd?

Regards,

Hello @RobertCNelson,

It works.

Seth

P.S. I am sorry to issue this statement after I started to mess w/ it more. I figured out my concern. It worked all along. I just did not remember exactly what happened last time I tried to make it work.
