ECSPI enabling in iMX6ULL

[mathew_k_t]

Hi,I'm using iMX6ULL evk, and currently trying to enable ecspi but spidev is not foundin /dev. I have made changes in dts file and defconfig. Also enabled spi device driver in menuconfig. Please let me know what wrong in these changes.Do i need to change/add something.

Output of dmesg|grep spi ?

If there is nothing wrong in your dts, should see something like

root@wandboard-custom:~# dmesg|grep spi

spi_imx 2008000.ecspi: probed

Hello,

  I think it makes sense to configure SPI slave mode support in Linux (SPIDEV).
By default it is not supported, so,  I suggest to use the following sequence for SPIDEV :

$ bitbake linux-imx -c menuconfig

# select DEVICE DRIVERS -> SPI Support -> User mode SPI device driver support

$ bitbake linux-imx
$ bitbake core-image-minimal  

  The recent command is used to deploy compiled files to file system.

Have a great day,
Yuri
