I have been trying to setup the notduino board with the CW_lite capture board but I keep running into issues
Here is the code:
%run “…/…/…/jupyter/Setup_Scripts/Setup_Notduino.ipynb”
import chipwhisperer as cw
avr = scope.scopetype.dev.avr
avr.find() # [Errno 110] Operation timed out
print(avr.readSignature())
print(f"{avr.readFuse('low')}-{avr.readFuse('high')}-{avr.readFuse('extended')}")
Here is the error output:
WARNING:ChipWhisperer NAEUSB:Your firmware is outdated - latest is 0.30. Suggested to update firmware, as you may experience errors
See https://chipwhisperer.readthedocs.io/en/latest/api.html#firmware-update

I tried the code recommended in Troubleshooting:
import chipwhisperer as cw
scope = cw.scope()
scope.default_setup()
scope.io.tio1 = "serial_tx"
scope.io.tio2 = "serial_rx"
prog = cw.programmers.AVRProgrammer(slow_clock=True)
prog.scope = scope
prog.open()
prog.find()
prog.writeFuse("low", 0b11100000)
However, I end up with the same error message.
Thanks.
