Hi guys,
having trouble in the sca101 LAB “Connecting to Hardware”.
Keep timing out when trying to capture traces using cwnano.
(I tried using simpleserial2 and playing around with bytes being passed to simpleserial_write)
Is capturing traces a known difficulty with the nano?
I’m on ubuntu20.04 (not inside VM)
thanks for your time in advance
Hi,
I think the issue is with msg = b"0011...". While that has the type bytes, it behaves more like a string in that 00 is 0x3030, not 0x00. I’d recommend using a bytearray object instead.

Hi Alex,
Thanks for the reply.
Yes I tried a byte array (of varying sizes).
But that was also not a solution.
Cheers
Hi,
What bytearray lengths have you tried? The length of the bytearray you pass to simpleserial_write() must be exactly 16 bytes long, otherwise the target will reject the packet.
You may also want to uncomment the code that prints "hello\n" at the beginning of simpleserial-base to verify that serial is working in general. If you run print(target.read()) after programming, you should see "hello" if serial is working.

Awesome thanks Alex!
I’ll give this a go tonight after work
Thanks,
Ben
I updated the firmware (as you kindly helped me resolve) and will try again now to run the hardware setup with an up to date nano.
