printf while using UART in DMA mode

Hi,

silly question

i am playing with a ADZS-BF592-EZLITE board. I imported CharECHO_UART example but, after activating DMA mode with:

eResult = adi_uart_EnableDMAMode(hDevice, true);

the first printf method generates this error:

A non-recoverable error or exception has occurred.
Description: An illegal data memory access has occurred.
General Type: RunTimeError
Specific Type: DCPLBProtectionViolation
Error PC: 0xffa01440

This error does not happens if i do not use DMA mode.

It looks like printf is writing something into memory instead of printing on console
