Hi Robert, If I plugged the HDMI cable while I started the board with the LCD cape connected the desktop is displayed on the HDMI output On the LCD I have juste the backlight on but the touch panel is working.
I thought the HDMI should not work with my config ? It looks like the file uEnv.txt is ignored linux:~ # cat /boot/uEnv.txt dtb=am335x-boneblack-emmc-overlay.dtb bone_capemgr.enable_partno=BB-BONE-LCD7-01:00A3 2015-08-27 19:43 GMT+02:00 matthieu claire
