to BeagleBoard
Hello,
I am currently using a Beaglebone Black with these distribution :
Distributor ID: Debian
Description: Debian GNU/Linux 8.7 (jessie)
Release: 8.7
Codename: jessie
I tried to modify a dtbo file in /lib/firmware in order to disable all the buttons on the LCD7 cape.
Modification did not change anything so I decided to clean the whole folder to see if it changes anything. And surprise ! My LCD is booting up perfectly and everything is working.
Here is my dmesg with nothing in /lib/firmware :

I am currently using a Beaglebone Black with these distribution :
Distributor ID: Debian
Description: Debian GNU/Linux 8.7 (jessie)
Release: 8.7
Codename: jessie
I tried to modify a dtbo file in /lib/firmware in order to disable all the buttons on the LCD7 cape.
Modification did not change anything so I decided to clean the whole folder to see if it changes anything. And surprise ! My LCD is booting up perfectly and everything is working.
Here is my dmesg with nothing in /lib/firmware :
