[i.MX8MQ EVK] spi_master spi0: I/O Error in DMA RX

[jhpark_vine]

We use ecspi0 bus  as a interface to Wifi Module.

When we send a data file to  i.MX8MQ evk  via Wifi ,  it displays a I/O Error in DMA RX in spi0 device .

but, wifi connection works. 

How can fix this problem?    

Maybe this is related a DMX transfer problem 

Out dts config as follows .
