# This class allows to output in deploy folder, along with the built image, the
|
|
# 'flashlayout_${PN}' sub-folder, populated with the flashlayout files to use
|
|
# with our STM32MP programmer tool to load the binaries in target device and
|
|
# partitions.
|
|
#
|
|
# There are two configurations:
|
|
# * static:
|
|
# The user provides the flashlayout files to export with the built image.
|
|
# * dynamic:
|
|
# The user configures the different variables to generate the expected
|
|
# flashlayout files.
|
|
#
|
|
# --------------------
|
|
# Static configuration
|
|
# --------------------
|
|
# Set ENABLE_FLASHLAYOUT_DEFAULT to '1'.
|
|
# Configure FLASHLAYOUT_DEFAULT_SRC with the static flashlayout file locations.
|
|
#
|
|
# Configuration example (machine file or local.conf):
|
|
# ENABLE_FLASHLAYOUT_DEFAULT = "1"
|
|
# FLASHLAYOUT_DEFAULT_SRC = "files/flashlayouts/FlashLayout_sdcard_stm32mp157c-ev1_sample.tsv"
|

#
|

# Dynamic configuration
|

# ---------------------

|
|
# In order to automatically generate flashlayout files as well formated TSV file
|
|
# there are some variables to configure.
|
|
#
|
|
# Naming:
|
|
# <FLASHLAYOUT_BASENAME>[_<FLASHLAYOUT_CONFIG_LABEL>][_<FLASHLAYOUT_TYPE_LABEL>-FLASHLAYOUT_BOOTSCHEME_LABEL].<FLASHLAYOUT_SUFFIX>
|
|
#
|
|
# FLASHLAYOUT_BASENAME
|
|
# Default to 'FlashLayout'

|
# FLASHLAYOUT_CONFIG_LABEL

# Set from FLASHLAYOUT_CONFIG_LABELS list (without any '_' in config labels)
|
|
# FLASHLAYOUT_TYPE_LABEL
|
|
# Set from FLASHLAYOUT_TYPE_LABELS list
|
|
# FLASHLAYOUT_BOOTSCHEME_LABEL
|
|
# Set from FLASHLAYOUT_BOOTSCHEME_LABELS list (without any '_' in bootscheme labels)
|
|
# Note that both are appended only when FLASHLAYOUT_TYPE_LABELS and FLASHLAYOUT_BOOTSCHEME_LABELS contain more than two labels.
|
|
# FLASHLAYOUT_SUFFIX
|
|
# Default to 'tsv'

# Opt Id Name Type IP Offset Binary

|
# Specific configuration:
|
|
# FLASHLAYOUT_PARTITION_SIZE
|
|
# If configured, it allows to compute the next offset to apply in
|
|
# flashlayout file for the following partition.
|
|
# Note that according to the device in use for the partition a specific
|
|
# alignment size can be specified through DEVICE_ALIGNMENT_SIZE_<device>
|

# var where <device> is the current FLASHLAYOUT_PARTITION_DEVICE
