Interfacing (DSI, CSI, I2C, etc.) • Enable SPI 3WIRE Mode on Raspberry 5

Dear all,

I am trying to set the primary SPI interface using spidev_test[1] but I got an error in dmesg: spidev spi0.0: setup: unsupported mode bits 10
The error message comes from the spi.c#L3656 in following link.
https://elixir.bootlin.com/linux/v6.1/s ... pi.c#L3656

Does anyone know how to enable 3WIRE mode on Raspberry 5 and give me some hints? Thank you.
