Hello,

I recieve an error I did not see in previous run "VPSS_GRPX : please open fb0 node first.".

Does anyone know what's the reason for such error message from vpss/fbdev drivers ?

root@dm814x:/opt/dvr_rdk/ti814x# echo 0 > /sys/devices/platform/vpss/display0/enabled
root@dm814x:/opt/dvr_rdk/ti814x# echo 0 > /sys/devices/platform/vpss/display1/enabled
root@dm814x:/opt/dvr_rdk/ti814x# echo 0 > /sys/devices/platform/vpss/graphics0/enabled
VPSS_GRPX : please open fb0 node first.
-sh: echo: write error: Invalid argument
root@dm814x:/opt/dvr_rdk/ti814x# fbset -fb /dev/fb0
VPSS_FVID2: create handle is NULL
ti81xxfb ti81xxfb: fvid2 create failed.
open /dev/fb0: Invalid argument
root@dm814x:/opt/dvr_rdk/ti814x#

    For me is seems already disabled you could try:

    echo 1 > /sys/devices/platform/vpss/display0/enabled

    echo 1 > /sys/devices/platform/vpss/graphics0/enabled
