rtc and leds: more info
Hi all, I am still trying to make working hd leds and rtc
following your suggestion, now I am able to do this:
after booting the storage, I have:
storage01:~# lsmod
Module Size Used by
dm_snapshot 15712 0
dm_mirror 24960 0
dm_mod 51876 2 dm_snapshot,dm_mirror
leds_gpio 3072 0
led_class 3428 1 leds_gpio
doing a modprobe i2c-iop3xx I get the following output:
rtc-rs5c372 0-0032: rs5c372a found, 24hr, driver version 0.5
rtc-rs5c372 0-0032: rtc core: registered rtc-rs5c372 as rtc0
storage01:~# sysfs: duplicate filename 'rtc-rs5c372' can not be created

and echoing 1 to respective hd / amber works (led becomes amber)
What am I asking more ?
1st: autoload of i2c-iop3xx, in order to have rtc working at boot time: how to do ?
2nd: Ok, I make the disk's led amber or green but.. I would like to see them flashing.
If I echo 1 to hd1:green/brightness, The led stay off. Am I still missing anything
or the hw is not capable of doing it ?
Thanks,
ANdrea
