Wow,
So I was just here typing this problem up when I went back to try again and it worked so I deleted the post. As soon as I did the problem came back.
I did run the ChipWhisperer Setup Test.ipynb and it worked just fine.
I copied the Hardware code to the MAIN.
I didnt copy the creating a director but I did run it
I copied
SCOPETYPE = 'CWNANO'
PLATFORM = 'CWNANO'
Building the firmware
Then for connecitng to hardware I split it into three sections. it errors on section 2 or hangs on section 1. Like I said I reboot the VM and came back it hung the first time and then I reset the kernel and replugged the usb in and it work. Now it doesnt work at all. just fir SnG I restarted the kernel again and unplugged the USB and plugged it back in and it hangs on Section 1. I have 27 CWNANOs I can try others but I get the same for both of the two I have tried already.
section 1:
import chipwhisperer as cw
try:
if not scope.connectStatus:
scope.con()
except NameError:
scope = cw.scope()
Section 2:
try:
target = cw.target(scope)
except IOError:
print("INFO: Caught exception on reconnecting to target - attempting to reconnect to scope first.")
print("INFO: This is a work-around when USB has died without Python knowing. Ignore errors above this line.")
scope = cw.scope()
target = cw.target(scope)
print("INFO: Found ChipWhispererš")
The error reads like the USB is hung: If it is do I need to reboot the VM between every retest? That would be painful
