I can't remember what firmware I last wrote to this 32L, but you said that time that it was too big and the controller needed to be reflashed
I didn't have time to do it that time, but now I'm ready.

When I turn it on, the red LED lights up and the yellow one on the network connector barely lights up, it doesn't show any other signs of life.
