Some questions about ERROR_SPI_COM_FAIL during two motor working!

Hi, I am a fan of Odrive. During those days, I downloaded Odrive Code- RazorsEdge. When using code for two motors with AS5047P together, I found that those motors can’t work together. The error information is ERROR_SPI_COM_FAIL. But when using one motor, the system worked well. So how can I solve this problem?
Thanks a lot.
