Corrupted data on Serial number, product id with STM32CubeProgrammer

Rafa096 · ‎2025-07-03

Hi, after doing a full chip erase over a device with a STM32F103, it's impossible to download a new version over DFU with the STM32CubeProgrammer. After I press connect it shows up corrupted data on the Manuf. ID, Product ID and Serial Number parametres, and when I tried to download the firmware it threw an error.

The program crash if I press to many times the USB refresh button and If I press programming a few times. We change a few things related to memory on the device and I guess we messed up with something but I don't know how to recover the MCU after this.

Regards

Rafa

Are you sure that your "STM32F103" is genuine ?

Connect via SWD (eg, using ST-Link) and do a full chip erase?

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.

I hope it is:grinning_face_with_sweat:. We've been working with this chip for a long time and this is the first time that this happens.

Done this over JTAG using the ARM ULINK plus debugger on Keil and got the same results, actually the first screenshot was taken after doing this process...

Thanks for your response
