Beginner problem in tutorial B1

Embedded Security

I’m using CWLite two parts on VM with Lubuntu.
While programming the STM32F3, im unable to detect the device and send me the following error:

Failed to detect chip. Check following:

  1. Connections and device power.
  2. Device has valid clock (or remove clock entirely for internal osc).
  3. On Rev -02 CW308T-STM32Fx boards, BOOT0 is routed to PDIC.

I also tryied tutorial B2 and the same error occurs, if anyone can help me i would appreciate it.

Can you check the power and clock on the target board?

Sorry for the late reply, everything is well connected and I’m not sure how to check the clock on the target board. If you can guide me a little I will be very grateful.

If you have a logic analyzer or oscilloscope, check HS2 for the clock (available on the unpopulated 10-pin header next to the 20-pin connector).

Other things to check:

  • are you sure your USB cable is good?
  • reduce baud rate as explained in this post
  • is your VM USB controller set to USB 3.0?
  • can you try running natively, instead of VM?

Also I’m assuming that Setup_Generic.ipynb is running cleanly without any errors?

I checked the clock in HS2 and thats what the oscilloscope shows:

I have no idea if thats good or not, but the problem is still there. Also i checked the usb and is good. Im going to check the other points now.

Hello, i run chw in linux and i can capture traces (good ones, not like before that i only saw noise) and i can analyze it and recover a key. But i still cant detect the stm32f3 and it send me this error:

I dont really understand what is the task of stm32f3, why the attack is working if the software couldn’t detect it?
If u can help me with this will be great! if not, thanks always!
