OK, there it is, hidden under my ellipsis, thanks. Here are a few thoughts: [1] is the general docs which I'm sure you've read [2] Describes the process for a real board (with RSA, but the idea is similar) [3] Is a test for ECDSA so you should be able to follow along with the steps there to get something working If you have problems, then a console trace is often useful.
