13:14 TomyWork hi
13:16 TomyWork I'm on "Linux linux 3.14.60-fslc-imx6-sr #1 SMP Mon Aug 22 22:06:26 UTC 2016 armv7l GNU/Linux", lsmod lists the modules xt_connmark,rpcsec_gss_krb5,cpufreq_stats,bnep,iptable_nat,bluetooth,6lowpan_iphc,nf_conntrack_ipv4,nf_defrag_ipv4,nf_nat_ipv4,nf_nat,nf_conntrack,iptable_mangle,joydev,brcmfmac,nfsd,brcmutil,cfg80211,rfkill,ir_mce_kbd_decoder,ir_lirc_codec,lirc_dev,ir_sony_decoder,ir_nec_decoder,ir_sanyo_decoder,ir_jvc_decoder,ir_rc6_decoder,ir_rc5_decoder

13:16 TomyWork I'm trying to access the red front led
13:17 TomyWork acording to various forum posts it should be under /sys/devices/soc0/pwmleds.23/leds/imx6:red:front/brightness, however there is no pwmleds.23, only pwmleds.27, which doesn't contain "leds"
13:18 TomyWork the short name, /sys/class/leds/imx6:red:front/brightness, doesn't exist either
13:19 TomyWork i read that the feature was added in the 3.10 kernel. was it removed with 3.14?
13:20 TomyWork http://forum.solid-run.com/linux-kernel-and-bootloaders-on-cubox-i-and-hummin-f10/introducing-kernel-3-14-x-t1525-s100.html oh here's something to try
13:20 vpeter thuis doesn't work to turn off? echo 0 > /sys/class/leds/imx6:red:front/brightness
13:33 TomyWork -bash: /sys/class/leds/imx6:red:front/brightness: No such file or directory
13:34 TomyWork root@linux:~# cat /boot/config-$(uname -r) | grep CONFIG_LEDS_PWM
13:34 TomyWork CONFIG_LEDS_PWM=y
13:35 TomyWork i just put that there. before, it said somethign like "# CONFIG_LEDS_PWM is not set"
13:35 TomyWork rebooted, and the device still isnt visible
13:37 vpeter No device in /sys/class/leds/ ?
14:14 TomyWork just mmc0/1
14:14 TomyWork root@linux:~# ls /sys/class/leds/
14:14 TomyWork mmc0:: mmc1::
