I am testing the ATMega 32U2 on frank-v2
Currently I see what looks like good voltage levels on all the rails, but
is neither the ICSP nor USB seems to connect to the device. I think the
running ok, but I need to bring my oscilloscope in to verify this.
As such, anyone with experience give me advice on debugging this.
- Should the ICSP work if the crystal is not running
- Do the devices come with a USB downloader by default
If they do not, what is the best download tool to put on them to avoid
repeatedly ICSP them?
