For example, to show "boot", this snippet can be added (gpio pins and letter codes should be adjusted for different STB/LCD models): FD650_MODE_WRCMD='0 1 0 0 1 0 0 0' DISPON='0 0 0 0 0 0 0 1' FD655_BASE_ADDR='0 1 1 0 0 1 1 0' Z='0 0 0 0 0 0 0 0' B='0 1 1 0 0 1 1 1' O='0 1 1 0 0 0 1 1' T='0 1 0 0 0 1 1 1' setenv d0 gpio clear C22 setenv d1 gpio set C22 setenv LC gpio clear C19 setenv HC gpio set C19 setenv send 'run d0 LC; for b in $cmd; do run d$b HC LC; done; run HC d1' cmd="$FD650_MODE_WRCMD 1 $DISPON 1" run send cmd="$FD655_BASE_ADDR 1 $Z 1 $B 1 $O 1 $O 1 $T 1" run send How Has This Been Tested?
