Question about spi

Good day!
i have simple problem
i use colibri imx6.
when i use linux 5.7 or torizon core 5 spi work quite good.
but when i use linux 6.1 or torizon core 6 - spi not work
i guess on 6 kernel spi not working
Can somebody tell me, how to use spi on linux 6.0 and above ?

Hi ,

Thanks for your question.

There seemed to be a change/issue on TorizonCore 6 about SPI.

Can you try the method described there (disabling the CAN controller) and let us know if that made SPI work?

Best Regards

do you mean here ?

Hello ,
Yes, this one and also the ones in the issue description.

Best regards,

Thanks! i tried to use this manual
but it is not working.
SPI work good on 5.9 and lower. But on 6.0 and above SPI not working.

Best regards,

after long fight i got result. it was quite easy. i decided to use M in make menuconfig instead *. after i compiled modules and copy them to rootfs. After i use this:

echo spi3.0 > /sys/bus/spi/drivers/mcp251x/unbind

echo spidev > /sys/bus/spi/devices/spi3.0/driver_override

echo spi3.0 > /sys/bus/spi/drivers/spidev/bind

and Spi work nice
