SPI works 8-bits data frame ,it is normal.But I set up 9-bits data frame,ioctl call fail in user space.

How can LS1043ARDB board SPI driver(in kernel status) support 9-bits data send frame.

Which file should I modify?

I need help.

Find the /LSDK_1712/flexbuild/packages/linux/linux/drivers/spi/spi-fsl-dspi.c file.


Have a great day,
