Using ECSPI2 as Slave on IMX8M Mini running Yocto Thud

[dave_nugent]

Hi,

I am working with the IMX8M MIni EVK running Yocto Thud and have been looking into using ECSPI2. I have been able to enable it in the DTS file and use it as a master device. However I have not been able to use it in slave mode. Do you know if it's possible?

Build Configuration:
BB_VERSION           = "1.40.0"
BUILD_SYS            = "x86_64-linux"
NATIVELSBSTRING      = "ubuntu-18.04"
TARGET_SYS           = "aarch64-poky-linux"
MACHINE              = "imx8mmevk"
DISTRO               = "fsl-imx-wayland"
DISTRO_VERSION       = "4.19-thud"
TUNE_FEATURES        = "aarch64"

imx-4.14.98-2.0.0_ga.xml

Thanks!

Dave
