Problem in CW305_ECC

Hi everyone, I have already done ChipWhisperer Firmware Upgrade before I do this section(CW305_ECC), but when I follow the steps in CW305_ECC, some USBError happened


Does anyone know how to solve this error? Please help me.Thank you~

That’s strange, we should use the libusb1 backend on new firmware. Can you find both your capture and target boards in device manager and post the full error message?

Alex

This is the full error message and my device manager

Hi,

Can you uninstall the drivers for both the CW305 and the ChipWhisperer Lite in device manager? It looks like the devices are still using the old drivers. Instructions for that are here: https://docs.microsoft.com/en-us/windows-hardware/drivers/install/using-device-manager-to-uninstall-devices-and-driver-packages

Alex

Hi,
I tried to uninstall the drivers for both the CW305 and the ChipWhisperer Lite in device manager, and I plugged in again to rerun CW305_ECC, but still got some error.

And the device CW305 and the ChipWhisperer Lite in device manager will be below universal serial bus.Is it correct?

Yup, they’ve got the right driver now.

It seems like there’s been a few unintended changes with the newest FPGA bitstream. Can you try downloading https://github.com/newaetech/chipwhisperer/blob/9c8b5560fb6a954d24ee97dc4eb3091ff0a46484/software/chipwhisperer/hardware/firmware/cwlite.py and replacing chipwhisperer/software/hardware/firmware/cwlite.py in your ChipWhisperer installation?

The bitstream is programmed on startup+connect, so if you unplug+replug and reconnect, the new bitstream will be reloaded.

Alex

Hi Alex,
Do I need to reinstall driver(ex:cwlite_usbdriver and cw305_usbdriver) for my cwlite and cw305 board?

Oscar

I tried to download and replaced cwlite.py in your ChipWhisperer installation, and directly use ChipWhisperer Firmware Upgrade.ipynb to upgrade, and ten I go to execute CW305_ECC in Jupyter notebook,but when I run this one, it will get some error:

Do I need to reinstall driver(ex:cwlite_usbdriver and cw305_usbdriver) for my cwlite and cw305 board?

You shouldn’t use the ChipWhisperer firmware upgrade. You only want to reload the FPGA, which is done automatically when you connect.

If you installed old firmware, you need to download the original cwlite.py and repeat the original firmware upgrade again. Try disconnecting and reconnecting the power supply on your CW305, then connecting again.

Alex

How about reinstall driver(ex:cwlite_usbdriver and cw305_usbdriver) for my cwlite and cw305 board through device manager?

If they appear as universal serial bus devices, there’s no need to reinstall the driver.

After I tried it, it works.Thank you for your help,Alex.

Oscar

Thank’s for checking and letting me know. We’ve found another issue with that FPGA release recently, so it’s good to know there’s additional problems besides just the one we found.
