PROCESSOR-SDK-AM64X: PROCESSOR-SDK-AM64X

Hi,

I have generated an image (core-image-minimal) and successfully enabled UART and I2C and it is working properly on hardware,

But for systemD when I updated conf/local.conf by adding 

DISTRO_FEATURES:append = " systemd virtualization"
VIRTUAL-RUNTIME_init_manager = "sudo systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
VIRTUAL-RUNTIME_initscript = "systemd-compat-units"

and flash the image on board then while booting board is entering in emergency mood and gives the error of UBOOT partition . 

also the CP437 is already enabled in kernel. It seems like kernel is not up properly.

also for SPI I have updated conf/local.conf by adding below line, also SPI is already enabled in kernel

IMAGE_INSTALL:append = " kernel-image kernel-devicetree"

but inside the hardware SPI is not activated .

Is there anything else which I can do to start SPI and systemD on sitara processor hardware ?

layers I have added in conf/bblayers.conf

    This looks like a non processor-sdk-am64 question. Please do further reading on yocto image types and systemd configuration https://docs.yoctoproject.org/ref-manual/images.html 

    Question is not clear , on why standard yocto distro features are tried to be modified for SPI / kernel features.  core-image-minimal as the definition says , is for minimal yocto package. docs.yoctoproject.org should clarify more details on distro package and features options.

    For the kernel question, before we dig deeper, please clarify .

    1. Processor-sdk version used (This will give yocto , kernel, uboot details)

    2. For kernel modification you can modify necessary kernel changes and rebuild only kernel bitbake recipe after setting up environment.
