​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.

can we substitute the eval kit with a bug-free one,
to do some evaluations on potential applications we cannot reprogram the system.
we have bought the eval kit as free of bug
thank you

Hi,

I can suggest a workaround to solve this FW issue of initialization procedure.

Try to power-up the board and after RESET the device.

Please let me know if you are able to use the kit for your evaluations.

Cristiana,

I am having the same issue.

The red LED blinks meaning the system gets into fault mode as in line 135 of code: if (MC_GetOccurredFaultsMotor1() != 0)

Thank you in advance

EDIT: Problem Solved. I was having issues with the power supply. Once I fixed it and provided the motor with at least 30V power was asserted and the system ran well.
