Hi Support,

 

GitHub - boundarydevices/linux-imx6 at boundary-imx_4.1.15_2.0.0_ga 

 

We have already used spi-imx.c patch in attach github, however, this issue still happen when traffic are passing throughput SPI interface. Do you have any idea what we encountered ? Thanks a lot !

 

It looks like error in PIO not DMA...

 

nrc-cspi spi2.0: I/O Error in PIO
spi_master spi2: failed to transfer one message from queue

 

Regards,

Steven Yu
