Hello, I am currently trying to build an OS, which should run on a raspberry pi 4. In order to do so I have created a configuration file, which also determines the MENDER_UBOOT_STORAGE_INTERFACE to be the integrated ssd on my raspberry pi. After building the image and flashing the ssd of the raspberrypi the output I get is: “Failed to open device ‘nvme’”. So my question is, is there an option for specifiying a ssd boot with uboot and do I have to consider any additional parameters for the configuration file? My configuration file currently looks like this:
#
# This file is your local configuration file and is where all local user settings
# are placed.
# Mender Update
# The name of the disk image and Artifact that will be built.
# This is what the device will report that it is running, and different updates must have different names
# because Mender will skip installation of an Artifact if it is already installed.

MENDER_UBOOT_STORAGE_INTERFACE = "nvme"

# Allows bitbake to execute multiple tasks at once.
# For a quadcore, BB_NUMBER_THREADS = "4", PARALLEL_MAKE = "-j 4" would
# be appropriate.
# Also, make can be passed flags so it run parallel threads e.g.:
BB_NUMBER_THREADS ?= "${@oe.utils.cpu_count() * 2}"
PARALLEL_MAKE ?= "-j ${@oe.utils.cpu_count() * 2}"

#
# Package Management configuration
#
# This variable lists which packaging formats to enable. Multiple package backends
# can be enabled at once and the first item listed in the variable will be used
# to generate the root filesystems.
# Options are:
# - 'package_deb' for debian style deb files
# - 'package_ipk' for ipk files are used by opkg (a debian style embedded package manager)
# - 'package_rpm' for rpm style packages
# E.g.: PACKAGE_CLASSES ?= "package_rpm package_deb package_ipk"
# We default to rpm:
PACKAGE_CLASSES ?= "package_rpm"
#
# Extra image configuration defaults
#
# The EXTRA_IMAGE_FEATURES variable allows extra packages to be added to the generated
# images. Some of these options are added to certain image types automatically. The
# variable can contain the following options:
# "dbg-pkgs" - add -dbg packages for all installed packages
# (adds symbol information for debugging/profiling)
# "src-pkgs" - add -src packages for all installed packages
# (adds source code for debugging)
# "dev-pkgs" - add -dev packages for all installed packages
# (useful if you want to develop against libs in the image)
# "ptest-pkgs" - add -ptest packages for all ptest-enabled packages
# (useful if you want to run the package test suites)
# "tools-sdk" - add development tools (gcc, make, pkgconfig etc.)
# "tools-debug" - add debugging tools (gdb, strace)
# "eclipse-debug" - add Eclipse remote debugging support
# "tools-profile" - add profiling tools (oprofile, lttng, valgrind)
# "tools-testapps" - add useful testing tools (ts_print, aplay, arecord etc.)
# "debug-tweaks" - make an image suitable for development
# e.g. ssh root access has a blank password
# There are other application targets that can be used here too, see
# meta/classes/image.bbclass and meta/classes/core-image.bbclass for more details.
# We default to enabling the debugging tweaks.
EXTRA_IMAGE_FEATURES ?= "debug-tweaks"
#
# Additional image features
#
# The following is a list of additional classes to use when building images which
# enable extra features. Some available options which can be included in this variable
# are:
# - 'buildstats' collect build statistics
# - 'image-mklibs' to reduce shared library files size for an image
# - 'image-prelink' in order to prelink the filesystem image
# NOTE: if listing mklibs & prelink both, then make sure mklibs is before prelink
# NOTE: mklibs also needs to be explicitly enabled for a given image, see local.conf.extended
USER_CLASSES ?= "buildstats image-mklibs image-prelink"
#
# Interactive shell configuration
#
# Under certain circumstances the system may need input from you and to do this it
# can launch an interactive shell. It needs to do this since the build is
# multithreaded and needs to be able to handle the case where more than one parallel
# process may require the user's attention. The default is iterate over the available
# terminal types to find one that works.
#
# Examples of the occasions this may happen are when resolving patches which cannot
# be applied, to use the devshell or the kernel menuconfig
#
# Supported values are auto, gnome, xfce, rxvt, screen, konsole (KDE 3.x only), none
# Note: currently, Konsole support only works for KDE 3.x due to the way
# newer Konsole versions behave
#OE_TERMINAL = "auto"
# By default disable interactive patch resolution (tasks will just fail instead):

#
# Disk Space Monitoring during the build
#
# Monitor the disk space during the build. If there is less that 1GB of space or less
# than 100K inodes in any key build location (TMPDIR, DL_DIR, SSTATE_DIR), gracefully
# shutdown the build. If there is less that 100MB or 1K inodes, perform a hard abort
# of the build. The reason for this is that running completely out of space can corrupt
# files and damages the build in ways which may not be easily recoverable.
# It's necesary to monitor /tmp, if there is no space left the build will fail
# with very exotic errors.
