Yes, and it is my guess that the led driver module you speak of is compiled into the kernel. Hence will not show up using lsmod. Sometimes there is a kernel config file on the system you can grep to see if a certain module has been statically compiled in. But I'm not sure if that exists on that

This does beg one last question - as I am using expansion connector pins to provide chip selects for numerous peripherals, what is the default state of the AM335X pins at powerup, until the boot configuration is loaded? I've slogged through the TRM as best I could, but want to make sure we're

Re: [beagleboard] BBB P8/P9 GPIO pin availability

Well, by definition, the boot programming pins are going to have the pull-ups / pull-downs, so you know what they are going to be doing, until over-ridden. Most processors start up with the programmable pins as inputs, then move to the configured state. Anything else can be dangerous to the pins.
