Hi, I am trying to access leds from command line (through the terminal), but I am getting "Permission Denied" error and am struck on similar issues.Can you please help me to understand what's wrong.
Environment: a. OMAP 4430 Panda board b. Linux 2.6.36 and Android GB 2.3.3 c. I have integrated the leds and it is visible to me as "/sys/class/ leds/green/" & "/sys/class/leds/keyboard-backlight". When I perform, echo 1 > /sys/class/leds/green/brightness or echo 1 > /sys/class/leds/keyboard-backlight/brightness kernel tells me "Permission Denied". I use the regular init.rc file as given in the OMAPPedia website, with the changes done by commenting the line "#mount rootfs rootfs / rw remount" etc. Similar to this, I am executing the "yavta" tool (https:// www.gitorious.org/omap4-v4l2-camera/yavta) and that too is not executing the command, kernel reports me that no such file or folder is present. The tool is copied in the same folder and I run it as yavta -h What could be reasons? Please help me out. Thanks, ARVR. -- unsubscribe: android-kernel+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-kernel
