hello,
I recently followed chipwhisperer jupyter notebook tutorials,but I faced a problem in 1 - Connecting to Hardware.
I tried to upload a firmware to target, but failed.
Here is the error messages.

OSError: timeout
I used ChipWhisperer Husky, ChipWhisperer CW313, SAM4S Target Board.
How do I solve it?
