Hello,
I have a trouble connecting my CW305 via python.
I installed “Chipwhisperer.v5.5.0.Setup.64-bit.exe” directly for my windows computer.
When running below code it showed that USB Device no found.
But device manager has recognized CW305!
Did I miss some installation/operation steps so it doesn’t work?
from chipwhisperer.capture.targets.CW305 import CW305

bitstream_file = r"D:\APP\ChipWhisperer5_64\git\home\portable\chipwhisperer\hardware\victims\cw305_artixtarget\fpga\vivado_examples" \
r"\aes128_verilog\aes128_verilog.runs\impl_35t\cw305_top.bit"
scope = cw.scope()
self.scope = scope
target = cw.target(scope, fpga_id='35t',bsfile=bitstream_file, force=False)
self.target = target
OSError Traceback (most recent call last)
