Confusion in “1 - Connecting to Hardware”

1

Hi, I’m new to hardware and just getting started with the Jupyter notebooks.
I’m using Chipwhisperer Lite 2 part version with the XMEGA target.
The following code runs successfully only when I disconnect SMA cables.
Otherwise ‘OSError: XMEGA Command 20 failed: err=1, timeout=1’ occurs.
Is this the right situation?

cw.program_target(scope, cw.programmers.XMEGAProgrammer, “../firmware/mcu/simpleserial-base/simpleserial-base-CWLITEXMEGA.hex”)

Sounds like a bad SMA cable. Email support@newae.com and we will arrange for a replacement.

In the meantime, hopefully one of your cables is good, in which case you can leave the glitch port unconnected (it’s only required for the voltage glitch notebooks).
