[Gumstix-users] Robostix blue LED

[ericwade <eri...@us...>]

Hello all - quick question.

I noticed when I ran the `Flash-LED' code on my robostix, only the red and
yellow robostix LEDs lit up. 

Curious about this, I decided to try:

$ i2c-io 0x0b setdir g.3 out
$ i2c-io 0x0b set g.3 0

And I get no response (the middle LED remains off) - meanwhile, 

$ i2c-io 0x0b setdir b.4 out
$ i2c-io 0x0b set b.4 0

lights the yellow LED just fine.

Do I just have a busted blue LED, or could I be overlooking something more
obvious?
