​Hi @RDa F.1​ welcome to ST Community.

I think your problem could be related to a bug we found in the previous code version.

You can download the new revision of STSW-ROBOT-1 and check if the problem is solved.

Let me know if it is ok.

Dear Cristina,
thank you for the mail.
Following the user manual:
than we have power up the system *without loading any software*:
at this point the motor _do not show any initialization_.
Up to this point we have not use any software, we have use the eval kit
as-is, as from the user manual.
In the user manual there are not any tips about "load the software
before power on"
So I think that the problem it is inside the firmware of the control board.
Waiting for you kind reply
Best Ragards

​Hi @RDa F.1​ the know bug is in the pre-loaded firmware.

The STSW-ROBOT-1 is the firmware example of the EVALKIT-ROBOT-1 evaluation kit.

The main.c code was modified to solve the initialization procedure.

You can update the firmware using a SWD programmer/debugger supporting the STM32F0 family, like the STLINK-V3 from STMicroelectronics.
