Dear community,

https://community.nxp.com/t5/i-MX-Processors/Chip-Select-Toggling-Between-Bytes/m-p/1579621

Just I have faced this issue in CM4.

The best solution is handling GPIO individually also CM4 after all?

Best regards,

this solution is for A core, if you need use this for M core, you need disable in the dts file firstly

I wanted to know a way how to fix the issue SS can't stay low during transmitting.
I think I can't clear it completely.
So the best solution is separating and controlling individually SS as a GPIO.

what processor do you use? imx6q or imx8qm?
