nrc-cspi spi2.0: I/O Error in PIO

[stevenyu]

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

Hi Steven

issues for boundary devices software can be posted on its forum:

Wiki - Boundary Devices 

alternatively one can try with nxp linux releases from source.codeaurora.org/external/imx/linux-imx repository

linux-imx - i.MX Linux kernel 

Linux documentation

i.MX Software | NXP 

Best regards
igor
