Hi,
I am working with IMX8M Mini EVK and yocto project build details:
Build Configuration:
BB_VERSION = "1.38.0"
BUILD_SYS = "x86_64-linux"
NATIVELSBSTRING = "ubuntu-16.04"
TARGET_SYS = "aarch64-poky-linux"
MACHINE = "imx8mmevk"
DISTRO = "fsl-imx-xwayland"
DISTRO_VERSION = "4.14-sumo"
TUNE_FEATURES = "aarch64"
TARGET_FPU = ""
I made the dts changes and menuconfig as sugegsted in the thread : test code for checking ECSPI2 on iMX8M Mini EVK
I want to test the hw loopback : Can I short In the EXP_CN J1003 Pin 19 and Pin 21
and try running the testcode of SPI using mxc_spi_test1.out.
For testing hw loopback, apart from connecting the J1003 pin 19 and pin 21 together, any other hw care needs to take.
Regards,
Sreedhar

Hi Sreedhar
you are right, for loopback connecting J1003 pin 19 and pin 21 together
will be sufficient. No additional connections are needed.
