BluePill: Timeout: No data received from target

[eychei]

@hello,

I am trying to get this to work on a standard bluepill board without success.
Getting "Timeout: No data received from target" Error

What I tried so far:
-Using the precompiled firmware files
-Compiling attack and also target firmware
-Changing pcs and operation system: Windows WSL (Ubuntu), Virtualbox (Kali), Clean Linux PC (Ubuntu)
-Changed attack.c sleep.ms(15) to 30ms
-Changed Bluepill boards
-Changed PiPico W with PiPico
-Tried with unlocked stm32 firmware
-Tried every uart combination
-Tried with shorter cables and connecting directly to the bluepill without a breadboard

Nothing of the above helped, always the same error.

What I have noticed is that the GP25 LED is not powered or blinking in any state of the process.
Hope someone can help me out in finding the root of this issue.

Thanks

I have the same timeout problem, I couldn't solve it.

Im having the same issue, I used openocd to dump the sram after it was written and they are the same. Im on windows 10 and i kept getting an error where openocd was getting a messed up path so i changed line 295, and I put the .bins in the same folder as the python script.

["init", 'load_image "' + "target_usart1.bin" + '" ' + str(hex(SRAM_START)), "exit"],

Not really sure what else to try.

A similar situation, I tried on several stm32F1 chips, tried to cool the attacked board with alcohol cooled to -20 degrees. Getting "Timeout: No data received from target" Error. The supply voltage is supplied via a transistor switch, the pulse duration on the Vdd < 3 mcs, there are no capacitors.

Wow, alcohol cooling from the freezer, it still worked for the third time!
