Can't flash an STM32F3 chipwhisperer board

Sousou · August 12, 2022, 7:21pm

Hello,
I have a Chipwhisperer Lite, and I have two different boards the F4 and the F3. I pulled the last cw version from the Github repository, and installed it.
Now I tried to flash the F3 board, using a simple example of the tutorial the simpleserial-base.

When I execute this line:

cw.program_target(scope, cw.programmers.STM32FProgrammer, "../hardware/victims/firmware/simpleserial-base/simpleserial-base-CW308_STM32F3.hex", baud=9600)

I have the following error:

Detected known STMF32: STM32F302xB(C)/303xB(C)

I tried to change the baudrate, it did not help.
Any suggestions please?

Best,

Hi,

Is this a new issue, or has programming the F3 never worked?
Does the F4 still work, or do you get errors when programming that as well?
Which baud rates have you tried?

Alex

Sousou · August 15, 2022, 3:03pm

Hi Alex,
The F3 has never worked for me, I even tried different f3 boards.
F4, and XMEGA both work.
I tried different baudrate starting from 9600. My chipwhisperer version is 5.6

Best,

Alex_Dewar · August 15, 2022, 3:39pm

Which higher baud rates have you tried? I’ve found that baud rates that are too slow also don’t work.

Another method you could try is the new JTAG/SWD programming support: Debugging with ChipWhisperer — ChipWhisperer 5.6.1 documentation

Alex

Sousou · August 15, 2022, 4:46pm

The maximum I used is 38400

Alex_Dewar · August 15, 2022, 6:48pm

Can you try the default of 115200 as well? Also, can you try running cw.target_logger.setLevel(cw.logging.DEBUG) before programming and sending me the output?

Try modifying the timeout on line 487 of chipwhisperer/software/chipwhisperer/hardware/naeusb/programmer_stm32fserial.py to be 1000000 instead of 30000

Alex

Sousou · August 17, 2022, 2:28pm

I still get the same issue

Alex_Dewar · August 18, 2022, 6:26pm

I’m not too sure then, since everything should basically be the same between the F3 and F4. Maybe try shorting the SHUNTH and SHUNTL pins just to make sure the voltage isn’t dropping too low on the F3.

Were you able to solve this error please?
