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...
