After updating the Chip Whisperer firmware, I’m still not able to run the basic chipwhisperer commands. I am currently using the CW1200.
import chipwhisperer as cw
scope = cw.scope()
scope.upgrade_firmware()
Here’s what I have done
Hi,
You’ll have to use the older firmware update method: API — ChipWhisperer 5.6.1 documentation
That update method will be available in the next ChipWhisperer release.
EDIT: You might want to run through chipwhisperer-jupyter/ChipWhisperer Updating.ipynb at master · newaetech/chipwhisperer-jupyter · GitHub and grab the latest commits, as there’s been a lot of changes since the last release. If you do that, you’ll be able to use the scope.upgrade_firmware() method.

scope function which is what is triggering the error from the post above.Are there any work arounds to this. I’ve manually updated to ChipWhisperer 5.5.2 but the firmware issue still persists. I went through the updated commits you suggested chipwhisperer-jupyter/ChipWhisperer Updating.ipynb at master · newaetech/chipwhisperer-jupyter · GitHub but I am unable to call the scope.upgrade_firmware() method due to the issue mentioned above.
That cw.scope() call from your first post did work. You can see in the error message that scope.upgrade_firmware() is what failed, not the cw.scope() call. What’s the full stack trace of the second error you got?
Alex
@Alex_Dewar thanks I don’t know what is wrong with the installation build. Here is my stack trace, I tried troubleshooting the errors but still wasn’t able to get anything. Let me know if a solution comes to mind.

Huh, I don’t think I’ve seen that error before - maybe something’s wrong with libusb? Try doing
%%bash
pip uninstall libusb1
pip install libusb1
In jupyter

Greetings,
I have the identical problem. After looking at this page, I tried @Alex_Dewar’s solution by using libusb codes. After that, I got these messages-please see photos attached. Please help me out in this regard.
Thank you,
Whoops, sorry, forgot pip asks for confirmation. Try doing pip uninstall -y libusb1 and pip install -y libusb1.

Hi @Alex_Dewar ,
After trying your idea, a connection problem occurred. Therefore, I ran Zadig.exe and successfully installed the usb driver. After that, the device manager showed the virtual box usb, which is my cw1200, in the Universal Serial Bus Devices part. However, I still get a connection error and cannot eliminate the screen on the capture tool that @fuzzingdolphin uploaded here. Please help me in this regard. Note that I installed the Blackhat 2021, which is chipwhisperer 5.6.0. Thanks in advance.
