Echo a value to the bind file that represents the framebuffer console
driver. So assuming vtcon1 represents fbcon, then::
- echo 1 > sys/class/vtconsole/vtcon1/bind - attach framebuffer console to
+ echo 1 > /sys/class/vtconsole/vtcon1/bind - attach framebuffer console to
console layer
- echo 0 > sys/class/vtconsole/vtcon1/bind - detach framebuffer console from
+ echo 0 > /sys/class/vtconsole/vtcon1/bind - detach framebuffer console from
console layer
If fbcon is detached from the console layer, your boot console driver (which is
CONTROL REGISTER(0x09).Flash mode is activated by the ENABLE REGISTER(0x0A),
or by pulling the STROBE pin HIGH.
-LM3556 Flash can be controlled through sys/class/leds/flash/brightness file
+LM3556 Flash can be controlled through /sys/class/leds/flash/brightness file
* if STROBE pin is enabled, below example control brightness only, and
ON / OFF will be controlled by STROBE pin.
OFF::
- #echo 0 > sys/class/leds/flash/brightness
+ #echo 0 > /sys/class/leds/flash/brightness
93.75 mA::
- #echo 1 > sys/class/leds/flash/brightness
+ #echo 1 > /sys/class/leds/flash/brightness
...
1500 mA::
- #echo 16 > sys/class/leds/flash/brightness

Torch Mode
^^^^^^^^^^
REGISTER(0x09).Torch Mode is activated by the ENABLE REGISTER(0x0A) or by the
hardware TORCH input.
-LM3556 torch can be controlled through sys/class/leds/torch/brightness file.
+LM3556 torch can be controlled through /sys/class/leds/torch/brightness file.
* if TORCH pin is enabled, below example control brightness only,
and ON / OFF will be controlled by TORCH pin.
OFF::
- #echo 0 > sys/class/leds/torch/brightness
+ #echo 0 > /sys/class/leds/torch/brightness
46.88 mA::
- #echo 1 > sys/class/leds/torch/brightness

Indicator Mode
^^^^^^^^^^^^^^
-Indicator pattern can be set through sys/class/leds/indicator/pattern file,
+Indicator pattern can be set through /sys/class/leds/indicator/pattern file,
and 4 patterns are pre-defined in indicator_pattern array.
According to N-lank, Pulse time and N Period values, different pattern wiill
pattern 0::
- #echo 0 > sys/class/leds/indicator/pattern
+ #echo 0 > /sys/class/leds/indicator/pattern
...
pattern 3::
- #echo 3 > sys/class/leds/indicator/pattern
+ #echo 3 > /sys/class/leds/indicator/pattern
Indicator brightness can be controlled through
sys/class/leds/indicator/brightness file.
OFF::
- #echo 0 > sys/class/leds/indicator/brightness
+ #echo 0 > /sys/class/leds/indicator/brightness
5.86 mA::
- #echo 1 > sys/class/leds/indicator/brightness
+ #echo 1 > /sys/class/leds/indicator/brightness
...
46.875mA::
- #echo 8 > sys/class/leds/indicator/brightness
