Here are information how to dump STM32F1: https://blog.zapb.de/stm32f1-exceptional-failure/ |

The paper I linked found success in using power glitching to bypass the bootloader check. Power glitching is non-invasive, right? |

Hi! Someone have found a way to fix the attenuation network impedance for low ranges (less than 500mv)? I see that during attenuation there is active the 49.9ohm resistor after the opa, then the network of 100-510-100 resistors, giving 2 voltage dividers, one 49.9/100 and the other one 510/100. I have an fy6900 and have the same problem (plus a pcb design error so that the 2 100ohm output resistors after the ths are not in parallel, but this is another story :palm:) Thanks! |

I found this paper that extracted firmware from an STM32F1 series MCU 'easily': https://tches.iacr.org/index.php/TCHES/article/download/7390/6562/ Page 9/10 (207/208) Sounds like a fun project. Edit: And by an interesting coincidence, this paper specifies a FeelTech unit for generating their attack glitches. --- End quote --- |
