evalL6474PD not working

 i bought two different ST motor eval boards connected to the STEVAL-PCC009V2; eval6470PD and eval6474PD. the eval6470PD works fine but i want to use the eval6474PD for technical reasons ( current vs volt control). the eval6474PD does not work. I requested a second replacement and it also does not work using the STSPIN windows control. Signal look ok but not motor movement
