Hi,
When I run the
trace_test = cap_pass_trace("h\n")
#Basic sanity check
assert(len(trace_test) == 3000)
print("✔️ OK to continue!")
cell in the SOLN_Lab 2_1B - Power Analysis for Password Bypass notebook, I get the following error:
AttributeError Traceback (most recent call last)

I’m using the VM in VirtualBox on a windows 10 host, with the ChipWhisperer CW1200 scope and STM32F3 target on the CW308 UFO board. Both of those are set correctly in the notebook as well, as far as I know (shown below)
SCOPETYPE = 'OPENADC'
PLATFORM = 'CW308_STM32F3'
VERSION = 'HARDWARE'
SS_VER = 'SS_VER_1_1'
How do I fix this error?
