Hello,
I just received my ChipWhisperer-Lite and the target board: CW305. I am using Windows 10 and I installed ChipWhisperer 5.5 directly (no VM). The USB driver of CW305 was automatically installed. However, I have installed the USB driver for ChipWhisperer-Lite (through device manager). For FPGA is XC7A100T: the M0M1M2 switch is “111”, the led light situation is following: on cw305, the led8(green) is on, the led1(red) is flashing, and the led FPGA_DONE-ON=Unprog(red) is on;
For CW-lite: blue (continuous blinking blue light) and others are off.
I am having great difficulty trying to program the CW305 target board. The scope = cw.scope() command is not working. Did I miss some installation/operation steps so it doesn’t work?
I believe this based upon running the following commands:
import chipwhisperer as cw
scope = cw.scope()
giving the error: chipwhisperer5_64\git\home\portable\chipwhisperer\software\chipwhisperer\hardware\naeusb\naeusb.py", line 354, in open raise OSError(“Failed to find USB device with S/N %s\n. Found S/N’s:\n” + snlist)
