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.
Tks!
Find the /LSDK_1712/flexbuild/packages/linux/linux/drivers/spi/spi-fsl-dspi.c file.
Have a great day,
Pavel Chubakov
