MC_FOC_DURATION

Dear all,
i'm building an application using STM32F303 and FOC Library 4.1.
We're using a custom board with three shunt topology.

PWD is 16kHZ and the motor runs up to 26k rpm. I use hall sensors for the statup phase and the switch to sensorless mode. Everything worked like a charm until i atted some functions using DMA (one is used to write on an SD Card and the other is used to draw a bitmap stored in flash on a LCD controlled via FSMC).
When thes functions are called the MCI_GetSTMState returna and error state and MCI_GetOccurredFaults returns MC_FOC_DURATION.
Does anybody have an idea of what can be the cause of this issue?
