Problems with LED pattern and keyboard light

Hi guys

I have problem with LED patterns and keyboard light. They don't work and when I try to LED Patterns program and do LED test there is error msg: "Exit status: 65280 faild to set red led current"

Anybody knows what is wrong??

This is the LED pattern editor failing to open /sys/class/leds/lp5523:r/led_current for writing. Could you open the terminal and check if it exist?

Code:

~ $ ls /sys/class/leds/lp5523:r

brightness   led_current  subsystem    uevent

device       power        trigger

Is the LED driver loaded (does the led_class and leds_lp5523 kernel modules appear in lsmod output)?

Code:

~ $ lsmod | grep leds_lp5523

leds_lp5523           9792  0

led_class             2948  2 leds_lp5523,leds_twl4030_vibra

no such file or directory

"twl4030:vibrator" is the only folder i have in /sys/class/leds

Re: Problems with LED pattern and keyboard light

Same results here too

the LED drivers is loaded but there is no such files in the /sys/class/leds only twl4030:vibrator

:(

If these files were deleted any way to get it back?

Can you check what appears in the dmesg output when you remove and reinsert the kernel module (needs rootsh installed)?

Code:

~ $ sudo gainroot

/home/user # rmmod leds_lp5523

/home/user # modprobe leds_lp5523

/home/user # dmesg

...

lp5523 2-0032: LP5523 Programmable led chip found

Re: Problems with LED pattern and keyboard light

Ok done all that but strangely there is no line with 'lp' in it.

Re: Problems with LED pattern and keyboard light
