Hi,

It looks like you flashed your ChipWhisperer with the Lite firmware instead of the Pro firmware. To fix this, you’ll need to open the unit and short the ERASE jumper, as described in this post: Failed to Update Firmware of CW1200, ChipWhisperer-Pro. If you need additional instructions here, let us know and we’d be happy to help.

Once you have the firmware erased, replace hardware_type='cwlite' with hardware_type='cw1200', as described at https://chipwhisperer.readthedocs.io/en/latest/api.html#firmware-update and repeat the firmware update.
