Hi @ah4711 ,
I noticed a conflict in assigning the pins to the corresponding functions.
[ 5.829428] imx6q-pinctrl 20e0000.iomuxc: pin MX6Q_PAD_NANDF_D4 already requested by 20e0000.iomuxc; cannot claim for spi0.0
[ 5.840838] imx6q-pinctrl 20e0000.iomuxc: pin-195 (spi0.0) status -22
[ 5.847385] imx6q-pinctrl 20e0000.iomuxc: could not request pin 195 (MX6Q_PAD_NANDF_D4) from group gpio2io04grp on device 20e0000.iomuxc
[ 5.859811] mcp251x spi0.0: Error applying setting, reverse things back
[ 5.866597] mcp251x: probe of spi0.0 failed with error -22
Are you planning to use the SPI interface in your application? If not, then you might consider disabling the Interface to prevent the conflict.
Best Regards
