The little things

It is the little things that make me happy sometimes, like Koen adding support for the Linux LED driver.

Several triggers are possible, such as accessing the NAND, MMC/SD, or just a regular heartbeat, as Koen has demonstrated. To list off the possible triggers for the LED driver:

root@beagleboard:~# cat /sys/class/leds/beagleboard\:\:led0/trigger
none nand-disk [mmc0] heartbeat timer

The above shows the MMC/SD access trigger enabled. Koen selected that by issuing the following command:
root@beagleboard:/sys/class/leds/beagleboard::led0# echo mmc0 > trigger
Get started adding your own drivers today by starting with the existing code and the kernel git tree. See (Thanks Dirk!) for references. The patch was discussed on the IRC channel here:

Meanwhile, Sakoman and Khasim are continuing to to push ahead with the full NAND flash support. All these "little" activities really make me happy. :)
