'NoneType' object has no attribute 'wave'


I am trying to do lab (Lab 2_1B - Power Analysis for Password Bypass (Hardware)), but i have the following errors and warning , any body have any idea?

Did you compile the correct firmware and program your target?

yes, as shown in this pic, and i have this error:
AttributeError: ‘NoneType’ object has no attribute ‘wave’,and No trigger

You’ve programmed firmware for the STM32F2, but you have an STM32F3.

it is working probably, thanks a lot
