Re: No Boot-Up (after spikes)

Hello Ted,

Sorry about the mishap, but it has happened to quite a few of us before.

I would try the Raduino off the main board but connected to a PC for supply via USB.

If it is gets stuck at firmware version I would suspect either a defective si5351 clock generator or an issue with the i2c bus (A4/A5 from memory). Check for shorts, and if you have a scope check that you get a 3.3v swing on the two i2c signal wires.

73, John
